@@MrFitzfn if it’s never been done before, drain it and measure how much you remove. Then replace with that much. You can also find specs on the Google or pay $20 for access to alldata’s website 👍

@sstressfl thank you I will let you know how it goes , I just got a service transmission light that recently came on

When you say shutter and shifts are you referring to when it feels like it lags during 2nd gear? I have a 2016 cadallic ATS, and just found out I need to replace the transmission fluids and have it drained!!

It did.

@@jeromeshockley9572 how many quarts did you put ? & is there a filter in xts ?

@@priptalsingh3076 I sold my XTS. I had my transmission fluid changed out by a reputable transmission shop. Don't remember how many quarts was put in to the transmission but I was informed by the service tech that the transmission has NO filter that needs to be replaced. The problem went away afterwards. I flip cars as a hobby so this was my last project before the COVID Pandemic hit. I bought the XTS dirt cheap at 121,000 miles. The shuddering issue around the 122,000 mile mark.

Nice! I have always wanted a legit garage with a high ceiling and a REAL lift! For now, I got ramps lol Glad it worked for you.

@@VelleyIndustrial I'm aware! I did a drain, measure and replace what was drained. That plug on the pan is a measuring stick so to speak :)

Good tips! There’s an older service bulletin online where they change the fluid 3x this way to get the tc fluid as much as possible. That was my plan, to do it again soon, but once I took it in to the dealer for a different problem, I asked them to diagnose the shudder. And they did. The previous dealership told me it was not bad enough yet and I didn’t press. Which is why I changed my own fluid. And as you can see, it seriously needed to be done. My car is at a new dealership and they have been magnificently helpful. 👍 ThAnk you for your feedback 🙏

@@sstressfl Like you I have experienced a really bad dealer and a really good dealer - thankfully in that order :) The new dealer has taken care of me fully and really fixed every problem i bring in so i now reasonably trust what they say.

Flushing the tranny cause more damage to your Valve body and solenoids. Best way itS to drop the pan and drain, Change Tranny oil filter , Don’t use DEXRON VI that stuff is junk and what makes your tranny fail! Use Mobil 1 LV ATF HP. Then wait 2 weeks and do the same drain and fill and tranny oil filter change and thats how you get all that Old Dexron VI out .

I recently got the valve body replaced and transmission fluid flushed as well for the same reasons. How is yours holding up after they did this?

Thank you 🙏

The ats 6 speed calls for a 35k fluid and filter change. And the volume of shavings and clutch material is not normal when shuddering due to contamination starts at 20k. It’s excessive. My 100k transmission fluid change in my Dodge Grand Caravan looked about the same which was expected at 100k.

@@sstressfl you obviously drive the Cadillac a little bit more spirited than you do the Dodge.

@@markk3652 I drove it like a baby because it kept breaking. I have a whole series of videos. The car lived at the dealership.

Thank you 🙏

Like I said in the video, it might require multiple pan drops to get rid of the shudder. GM says 3x is usually required. A flush is a great way to get it done if you have access to a trusted mechanic. Besides, the 8 speed will need a flush every 30k miles to keep it from shuddering. The 6 speed will usually only require one in its lifetime. But also this was diagnostic for me. It proved that contamination was the root cause of the shudder.

Thats great advice! The dealer ended up flushing it. It's fine now! But shy of a power flush, the valve body could have stuff stuck in it.

You speak truth!! :) I do know why you're saying not to flush, but on a newer transmission like this one that is filled with excessive metal and clutch sludge that causes shuddering, a flush is the actual solution dictated by GM (albeit temporary until it fills up with contaminant again). Doing it manually helps tremendously though. Especially if you do it multiple times like you did. An older transmission that has been neglected can start shifting horribly after a flush... the process strips away sludge that is keeping it functioning. And I agree with you... I think an annual change on this transmission is required for long life. Thanks for your feedback and enjoy the ATS!

Thank you for your kind words 🙏❤️

I agree it looks almost normal, but I’ve changed a lot of trans fluid. This stuff is way too much for a car that started its problems at 20k. Even more than I’ve seen at 100k. That filter was completely saturated with clutch and metal material. With excess mixed in the fluid and laying on the bottom of the pan. So bad that line pressure was impacted to cause shifting issues.

@@sstressfl 6 or 8 speed?

6 speed! Similar issues as the 8 speed. But after initial cleanup the 6 speed should be ok. The 8 speed shudder will reoccur and need a flush again and again. Many 8 speed owners find every 30k miles to keep the shudder at bay.

At 100k yes. Not at 20k when the shudder started. The filter was saturated. Low Line pressure. None of this is normal.

I did not! I read that 3 fluid changes are almost equal to a flush. I had planned to do 3... at least try 2, but then my car ended up at the dealership and they took care of it. And thanks for the feedback! :)

Thanks Tom! In my life, it has always been a standard service (at different mileage with different vehicles) to drop the pan and change the filter. A flush was a rare service, usually tied to transmissions that had serious problems/contamination. And I did read that a flush can help clean an old transmission "too well" and cause shifting issues. But with these 6 and 8 speed transmissions from GM, especially well under 100k miles, the flush might be the only fix for the shudder... or a 2x or 3x home-fluid change.

Sorry it didnt seem obvious. Thats how I tightened it in the first wave. The round about was to make sure I didnt miss any.

That's a great idea! Thanks for sharing that tip.

Aftermarket! I read some reviews and bought one that people claimed worked very well. My trans feels great right now... I suspect the rear end is now an issue.

It’ll make a big difference. You might need to do it again later to get closer to perfect.

@@sstressfl Thanks Michael! I am going to get it flushed before I put the new transmission oil. Thats what the dealer also suggested.

@@jibranqureshi2027 I have same problem with ATS 2015. Did the trans.oil & filter change solve the problem?

@@DoctrZhivago Yes it did! I would say about 90% of the shuddering is gone. Do get it flushed a couple of times at least (I did the flushing process with a cheaper gear oil).

I have been so tempted but when I consider I have to change the filter anyway.... BUT, it has GOT to be so much cleaner than a pan drop!! Good for you, John!!

I have some plans to put the car into the air sometime this season. I’ll try to focus on that 👍

Uhhhg.... not good to hear. Any chance you can bring it back again until it’s right? My car is in the dealership right now for rear end noise. Will let you know what comes of that in the next video. Hope you get yours fixed proper.

@@sstressfl Don't get me wrong, the dealership has been great. But they are only allowed to do what GM authorizes. The cars has been great overall, enjoy driving it every day. But when it comes to noises in the rear suspension, won't touch it. Shuttering, just change the fluid and re-program computer. When I complained that it doesn't shift and drive the same, you get excuses that it's in your head. Now I've got the noise coming from the front driver side suspension. Only happens over 60 miles per hour and certain road conditions make it worse. Hopefully it's just an unbalanced tire or something simple. Love the car, hate the lack of support from GM. Enjoy your videos, subscribing now.

@@djmatropolis1 I truly cheer for Cadillac... I want them to build world class cars, and in my opinion the ATS reached a whole new level of "wow!" Its a shame some of the sourced parts are not up to the challenge. My best to you and your Caddy. And thank you so much for the sub my friend!

You think so? I've never seen that much material and especially not in a car with 40,000 miles. It's excessive. Steel. Aluminum. And clutch material. I've gone 100,000 miles in cars and not seen that kind of corruption. I'm about to change the transmission fluid in my 2015 Grand Caravan with 100k on the odometer. It'll be interesting to compare.

Nice vids by the way. I grew up at the track :)

@@zacharyball8009 i guess I misunderstood. I agree it looks very contaminated. And by normal you mean normal for this specific transmission then yes.... at 40k miles this 6 speed looks like other transmissions do at 100+k miles. I just dropped the pan on my 2015 Dodge Grand Caravan at 100k and it looked similar if not healthier. And the van’s transmission is smooth as silk and has never shuddered. And the Dodge has a recommended fluid change at 120,000 miles or 60,000 with heavy towing. The 6l45 is indeed a very weak and/or poorly designed/low quality transmission.

waleed alblooshi I believe this applies to your transmission and recommends a new fluid flush: gmauthority.com/blog/2019/08/tsb-seems-to-fix-8-speed-automatic-gm-transmission-problems/comment-page-3/

I put a link in the video description below... but this is it! amzn.to/3oeYpLP

A I it has been 90% better! It’s a must do. Also look for anything that could be out of tune on your car or dragging brakes or wheel alignment. In my experience so far all of that can add to shudder.

Should be the same :) Hopefully you see excellent results.

No not at all. The new Mobile HP fluid was designed with a little extra friction modifer to help with the probems in the 8 speed. Its Dexron 6 with a boost :) But many people use the regular GM fluid (AC Delco) with no problems. The important thing is to change it and get a new filter in their. If you have a serious shudder, multiple fluid changes (3) might be needed or a professional flush. Hope that helps!

@@sstressfl thank you . 🙏🏽

You have a 2016! That's the 8 speed transmission that is covered under the lawsuit. If you are still under warranty, they should do the fluid flush on your transmission per GMs instructions free of charge. Give them a call :)

Thank you Michael for your advises, I appreciate your comments...I'm going to see GM'S dealer this tusday.

@@ramonpulido4718 I am curious to hear about your experiences! My best to you 🙏

Yes I have heard that many times. An older high-mileage transmission can develop a bunch of tarnish and gunk inside which actually helps it keep working. Once you put fresh fluid in the trans, it "washes" the transmission and cleans some of the built up varnish and breaks up the gunk which can make the tired old transmission start to slip. However if I was faced with a shudder, I'd change the fluid and filter in a heart beat. I can't stand the shudder. But that's just me. To me its worth the risk. Plus the new trans fluid is synthetic. It doesn't gunk up like the old stuff. It's not my car. But if it was, I would risk it and chase after the fix and start with a fluid and filter change. Just be aware, that you might need to do it 2 or 3 times total to rid your car of all the old fluid. If it doesnt work and it starts to slip real bad, you'll need repairs or a new/used trans. You have to make that judgement call. But again, to me, I'd gamble on the fluid. And spend the money on the repair if I had to.

@@sstressfl good video and advice. I just bought my 2017 ATS and at 60k miles it had the shudder. Didn’t really notice it till after I left the dealership but I just got the transmission and filter change done earlier this evening. So far the shudder seems to be a little less but maybe it just needs time to circulate. We’ll see but good suggestion on the shudder regardless

@@xCaRnRAGEx Hey that's great! It should feel better with a pan drop change but that torque converter holds about 50% of the fluid so multiple fluid changes/filters are usually required to get it close to perfect. Hope yours gets better! If not, try it again. Hard to get all of the steel out. Did you get a chance to see the old fluid? The old filter? Did it look like mine?

AL I haven’t thought that far in advance lol Also I haven’t brake fluid flushed nor planned on it. I put new rear calipers in and added a lot of new fluid. That helps a bit. My next project will be rear differential fluid hopefully soon before the snow arrives!

Michael Byrne great! excited for that video

Changed it every 35k - 50k if u like peace of mind. Same with ur diff fluid.

Thank you! I did not. However, once I changed the fluid in the transfer case and added an ounce of friction modifier I restored a lost 2 mpg 👍

That oil was really black😅 And you made half a change, but it gives you about 50 k miles to drive.

Eight Mind ha!! Thank you for your very kind words 🙏😁 I appreciate it 🤗

@@sstressfl I found my wife on myspace 13+ years ago....YOU just NEVER know Michael. LOL. Keep the great content coming and GOD bless.

God bless you too!! And thank you for your comments & feedback :)

lol

Does not need to be hot! Do not go thru the gears. Drop the pan and change the oil. I read that others used 6 qts when they replaced their trans oil and so I measured to make sure that 6 qts was correct. I drained 6 qts and it’s as others have said. I added 6 qts. There is a process to replace all of the fluid but it requires much more fluid and the ability to pump it thru the trans while it is running. The best at home job I can do is to put in a new filter, new fluid. It will make a huge difference. Perfect? No. But you can try to change it again in the future and the new filter should have caught much of the remaining contaminants. The option is to pay the dealership to flush it for you. I hope that helps! Let me know how it goes for you!

Thaks for sharing your concern. I did a criss cross pattern to bring the pan down. I went around the block to make sure I didnt miss one. Sorry if you feel I didnt make that clear enough. Also the manual says 6.64 ft-lb (9nm) total torque.

Historically transmissions that have not been serviced get all worn and gummed up inside. New fluid has a way of cleaning it and washing away the gunk that was keeping things sealed. So sometimes after changing fluid on an old transmission.... it gets worse because the new fluid washes and cleans all the old gunky stuff out. So its a gamble. I usually go ahead and change the fluid and filter. If it makes things better then YAY! If not... then boooo, I'm paying for repairs. But if you want to try the Lucas stuff, feel free. You'll need to remove some fluid to make room for it. But I suspect you probably need a new filter inside that thing. Its gonna be clogged and causing low line pressure. Whatever you decide, if the transmission is giving you grief, you have to do something or it'll eventually leave you stranded somewhere. Praying for a good outcome!!

Thank you! And my jack lifts about 18-19 inches. Its a fullsize 3 ton jack.

@@sstressfl I just did the transmission fluid change. It was a bit intimidating at first, but I got it done and was easy. My fluid was dark red, still in decent shape. But I still changed it anyways including the filter. Again thanks for the video. It really helped a lot!

@@Kevin_13616 Thats great! It really isnt so bad, but def intimidating at first. The more ya do the less mystery and things get easier :) Thanks for the update! Glad the vid helped.

FAWAZ N Mobil 1 Synthetic LV ATF HP fluid👍

Awesome that the shudder is gone! But grinding is not good. Assuming it could have improper fluid level. The transmission is very sensitive to proper level. Were you able to measure the amount of fluid that came out? There is a way to verify the level using the fluid level bolt on the pan. I hope it's just improper level, but I hate that there is noise, it's possible you have some wear damage internally. A buddy of mine is having his 2013 ATS 6 speed auto completely rebuilt right now due to internal damage and his has been maintained by the dealership :( I pray that's not your situation. But start with verifying proper level first! Let me know what you discover!

@@sstressfl turned out the fluid was low ☹️I had assumed that my garage was level and thus, putting the car on 4 jack stands would identical to your case. So I only put in 6 quarts just like you did without actually measuring how much I took out. Turned out the garage has a freaking slope (the level tool confirmed it). I jacked up the front two axles up via the middle jack point (with backup jack stands on the sides) to make sure the car is level and do the transmission fluid level check at 122F (with an IR gun); no fluid came out of the drain hole. It took 1/2 more quart to be at proper fluid level. Apparently, tilting the car to the front caused 1/2 more quart to come out. At the end, the car now shifts smoothly on all gears. Hopefully my stupid mistake didn’t cause too much damage after about 100 miles of driving 😑

@@quangvu4093 Thats awesome news!! I think you'll be ok! WOOHOO! Love to hear a success story :) Have a great day and thanks for sharing!!

​@@sstressflhey man i have a 2014 Cadillac ATS 2.0 AWD, does it take the same fluid as you put in?

@@miguelbTGOD Yes its the latest version of Dexron 6, but with some friction modifiers to aid in shudder problems. I have also heard people used the ACDelco stuff with great results and its a little less expensive - this stuff >> amzn.to/3VBSWeJ

I felt SO safe with the ramps. And it keeps the car nice and level. My best!

You could take it to a dealer and let 'em pump it through ;) Or remove the overflow bolt and pump more fluid into the mix to dilute it yourself - but its driving better than it ever has since I bought it at 17k. Here's how I see it... It's NOT the fluid so much as it is the incredible amount of metal shavings. It needs a new filter asap. It needs the magnet to be cleaned off, it needs the pan to be wiped clean. Just like the magnet, the old filter was completely maxed out. I suspect the shavings in the bottom of the pan get sucked up while driving, press up against the saturated filter, restrict proper fluid flow, then fall back down into the pan when you stop driving. Shuddering, poor shifting, all of it is due to the shavings. Once you have the new filter installed it will grab the remaining metal shavings. You could change it again (as some ATS owners do) and replace the filter again. And the old fluid? Its synthetic! Its capable of many more miles, but it's the corruption of the fluid, not the viscosity of the fluid that needs to be fixed.

@@sstressfl This is exactly it. Your video helped me do my 2014 ATS and I had the exact same findings. TONS of metal shavings in the pan and the old transmission filter was fully gunked up. The old fluid didn't necessarily look bad as you said, it was just full of metal shavings and I would absolutely notice the shudder after highway driving. My ATS has ~55k and would shudder really bad, but just did the 6quart drain/refill with a new filter and it's a complete day and night difference. No shudder at all after long trips/highway driving and the car is much smoother in it's shifting. My next plan is to do the rear-diff drain/refill as I think this would help also. Thanks for your video, much appreciated!

@@maximusdpsimus2278 I'm so glad it helped! What a difference! I noticed Sport mode now shifts sooner and quicker. I plan on doing another fluid and filter change after this winter just to get more of those shavings and to inspect the filter again.

The transmission fluid interval I think is 35k on this car. It sure doesn't hurt to keep it fresh and clean! Especially that filter... once it gets filled with metal and clutch material, it gets blocked and lowers line pressure in the transmission. Its also possible you have a transmission issue (I cant be sure) but my attitude is do what you can do cheap and easy first! And, its hard to diagnose until you have fresh fluid and a clean filter.

Thank you!

lol only because you understand 😂 uhhg how did fluid changes get so scary expensive? The pan drop and filter change should give you a huge improvement. But about 50% of the old fluid is still in the torque converter so I have read that GM recommends 3 pan drops and filter changes (with driving in between) total to clean it out enough for normal operation. That can be annoying but just be ready to do it again if you need to 👍 such gorgeous and enjoyable cars to drive. I pray your transmission is smooth after your first pan drop 🙏 Thanks for sharing!

@@sstressflyeah definitely annoying to have to do it 3x, how long should I wait to do it the 2nd and 3rd? But yes definitely agree, beautiful cars I love everything about my CTS the worst part is just that hard shift into 2nd gear. Makes me wanna get rid of the damn car 😂 I’m going to do my first fluid change this weekend.

@@wolfkixs9022 Well, see if the fluid change helps. If it makes a change then you know that is the issue. Then if its still harsh shifting or starts getting worse again, 1-2k miles later, do it again. Or you can have someone power flush it. Praying you get it resolved 🙏 I can still feel the angst I had while owning that car.

@@sstressfl thanks for the quick replies man! I wanna do the fill myself but I’m debating on just taking it to a shop and having them flush it out completely. I’m on a couple Cadillac pages on Facebook and a GM tech commented saying a flush is required to “fix” the shifting. Cadillac had quoted me $600 for a flush only, but I assume any shop can do the flush right?

@@wolfkixs9022after I changed my fluid it was way better. But not 100% fixed. When I was at the dealer for an unrelated warranty repair I told the tech that the trans was still shuddering. He fixed it. He told me he did nothing. I later found out he wasn’t supposed to fix it under warranty. But another tech told me he did a flush. And there were software updates for the trans. So can any shop do it? No. I have read about shops that mess it up. So wherever you take it make sure they have a solid reputation 💪🙏 But the flush should fix it.

Those 8 speeds definitely need frequent fluid and filter changes to keep from shuddering. And uhhhhg I’ve had so many issues with the rear diff on this car! Sorry you’re dealing with it too. Sounds like the mean green was prett caustic. I use mequiars auto detailer wax to clean screens. It’s very mild and leaves a very clean finish.

I would!! It’s not like a transmission. It’s chunky metal inside with 3 seals keeping the fluid from dripping out. Also make sure the vent on the top of the differential is clear and breathing free. They get plugged easily. If it’s an AWD you can use Amsoil SVG fluid or the GM equivalent. If it’s a RWD use the GM fluid spec’d for that specific differential. 👍

Typically the fix for 6 speed shudder is trans fluid and filter flush. Sometimes (but more rarely) the torque converter needs to be changed. The manufacturer recommends fluid and filter change at 45k miles. After I changed mine it made a huge difference but not 100% perfect. Eventually the dealer used a proper flush to replace 100% of the fluid and that is what finally fixed it. I hope that helps.

If any place shy's away from a flush its because they will refuse responsibility if ur car stops shifting. They will tell you they warned you.. but in reality what they dont tell you.. is a flush could possibly ( break loose material caked inside the transmission ) and it will no longer catch gears.. now what the service advisor should've told u is a drain & fill with a replace of gasket & filter isnt the same thing. Thats what u seen in this video. Drain & fill with new filter and gasket.. idk why places dont explain this too customers. Oh plus dealers usually want proof the atf was changed on time usually before claiming responsibility for destroying ur car.. lmao

Thank you my friend 🙏❤️

Was there any change when you changed the fluid and filter? If no improvement, it could indicate you have another issue. If it was better then change it again. Or take it to a shop a d have them power flush the system. I hope that helps 👍

I started mine as soon as I got it back on the ground. I let it idle for awhile to warm up a little then went for a drive :) It was VASTLY improved!

lol... the face splash is a very real risk! But the reason they do transmissions this way (at least I always thought so) is because you need to replace the filter. And the only way to do that is to drop the pan. Sadly that fluid check bolt won't help you to empty it. I have heard of people adding drain plugs to their pans! But that won't save you for this fluid change. Wear safety glasses! :)

@@sstressfl Yeah, I am still planning on ultimately dropping the pan. I just thought if I put the pump tube in there first, I could get maybe get most of the fluid out before I did.

HUGE improvement. I have found that I still have some after an hour drive, fully warmed up, usually at 70 on the hwy going up hills. But the contamination is the reason why it shudders. It has to be done. A new filter has to be installed. New fluid must displace the old stuff. It makes all the difference.

You have the 6 speed auto just like me. I know some people that have changed their fluid at higher miles and did not have any issues. But you could always call a Cadillac dealer and simply ask if they think it's ok. Or... you can visit cadillacforums.com and post a question. They are quite the group of smart folks that like playing with cars.

The filter came with a new one. The old one looked like new and had no rips or damage so I used it. But it’s there if you care to pull the old one from its perch and tap in the new one.

Amazon is good! Great price too 👍 6 will do it 💯 Gasket is completely reusable. It’s actually meant to be reused. Don’t forget the filter!

Michael Byrne lol yeah I already picked up the filter today from the dealership. I should have just picked up the fluid as well but thought I could find Mobil 1 locally because I wanted to do it tomorrow. Guess I’ll have to order it. Thanks for your help

Just added a link in the description below the video 👍 Thanks for asking! The link might help some others too 🙏

@@sstressfl Thanks so much!

I finally got around to updating it. Thanks!

This was experimental and it proved worthy! But right after this, the car has been in and out of the dealer for warranty work ever since. More than 100+ days and counting :/ I have the transfer case and front diff fluid, and Winter has finally ended but I haven't had the car..... and it's still at the dealer.

@@sstressfl I bought my 2018 ATS a half year ago and I have a sound on the front driver side of the car that sounds like a grimy wheel bearing took it in they said it was a broken wheel hub still makes the noise to this day I feel your pain with the ATS it’s a shame because it seems like the car is built really well but many people online seem to have countless problems with this car

@@AssassinsxNiGHT It is by far the most incredible fun driving car I have ever owned and at the same time.... the worst car I have ever owned. Sorry you're experiencing that noise. It completely ruins what would otherwise be an amazing driving experience.

With a pan drop and filter change, for me, it got 90% better. But some have told me theirs was 100% better afterward. Half the fluid is inside the torque converter so if the contamination is bad, it'll continue to shudder until you change it again and perhaps even a third time before its 100% shudderless. The most efficient method, obviously, is to get a transmission flush by a shop that you trust. If you don't have that... the manual pan drop is the best :) Hope that helps!

@@sstressfl it does! But I watched a few more videos and apparently some people have a shudder when driving. Mine is fine while I’m driving, but when I’m idling I can feel a slight shudder; think that’s the same issue possibly?

Around 35k. Maintenance interval is 45k but it couldn't wait. The shudder and sluggish shifting was getting bad.

My car? It has 50k on it now and yes its running great. It still has a minor vibration under load that the dealer never fixed. But after I changed the fluid in this video it was much better but needed one or two more fluid changes to make it 100%. But before I could do that the engine had problems and I took it to the dealer to be fixed under warranty. While it was there I asked them to look at it and they fixed it. I was told they did a full flush and it worked. I havent had shudder since then.
