Master getting your Tacoma into "AT Temp Check Mode" here: kzfaq.info/get/bejne/p9yTmqypvJ-6oXU.html

What a great video tutorial!! I have a 2011 4.0 4x4 I purchased with 80k almost 3 years ago and I've got 104k on it now. I never had any issues with the trans until I took it on a 5hr drive. When I was about an hour from home my overdrive went out. I took it to the dealer to have them check the fluid level and it was 2 quarts low. They topped it off and I have not had anymore problems since.

You’re the man! I mistakenly drained the AT pan instead of the oil. You make great videos!

Your video was a life saver. I accidentally drained my trans pan. Ya don't ask why I made that mistake. Your video gave me all the information I needed to fix my mistake. Oh and my Taco in a TDR Off-Road as well and at 15K miles I only had 2.5qts come out as well. Seems like the underfill or fill to a spec from the factory.

Awesome dude, the most comprehensive tutorial for Tacoma trans fluid change on the internet! I watched endless other videos and none of them covered all of the bases, especially the part of leaving the engine on while pulling the drain plug. They do mention it, but don't show it and leave it kind if ambiguous!

Thanks, I just did this on my '14 Taco. 94 000km on it, i drained 2500 mL of old fluid so very close to your 2 1/2 quarts.

so factory never added the correct amount since you had no signs of leaks... this tells me there is some leeway if you are a little under filled the trans still shifts correctly and may or may not last as long as a trans filled to proper levels.... they really should start putting trans dip sticks back on ...no dip stick is bs imo...try checking this level on side of the road if your tras is acting up...thats almost impossible...thanks for sharing

Was following your video (excellent shifting sequence in the other video btw) and went a little out of sequence, didn’t try the hex bolt before draining and now have a bricked tacoma lol. To the dealer we go tomorrow; replacing the 5 mm with the standard 14 mm is a great idea though

Tip for anyone doing this. Clean the 5mm hex out then take the back of your ratchet or hammer and tap the bit all the way into the head of the bolt. It won’t strip when it has the proper depth.

Great tutorial! Did the 120K tranny flush and refill on my ‘12 this past weekend. Great suggestion replacing the overflow plug with the 14mm to match the drain plug…Thx!!

Yeah realizing I missed a few maintainence items in my rush to keep skiing so I'm getting back on track, appreciate the instructions hopefully the temp check mode etc goes smoothly and I ordered a replacement drain plug just to have in case.

Another tip to add is that if your doing this in the summer make sure your car hasn’t ran for at least 6 hours. It was 110 here in Arizona and it keep flashing saying it was to hot to check. Came back the next day after work in the afternoon and as soon as I put it in AT CHECK mode it was already to temp because of the outside temperature

awesome video I hope this is the same procedure on the 3rd gen's and a helpful tip that I had learned from vw technician, before trying to loosen hex key bolts and possibly stripping out the head get a tube of valve grind paste (most parts stores carry this). Add a tiny smear inside hex then push hex key into bolt maybe tight but make sure it seats completely the paste will fill in any voids making a better fit and less of a chance of stripping out. also thanks for the tip on the drain plug and overflow being the same.

Very helpful video, especially with the AT Temp Mode linked too! One thing if you live in a hot area (AZ, TX, etc.), My trucks AT Temp light would go straight to blinking when I'd put it in Check Mode. I believe a 97F ambient temp prevented the trucks fluid from cooling down sufficiently. Had to wait till the next am to finish the job, which did the trick!

Just a Pro tip If you have a scan tool that monitors Trans fluid temp the temperature range is 97°f-115°f. I confirmed this with my scanguage2. When the “A/T check oil” light came on I turned off the truck and plugged in my scanguage2 and it was at 97°f. When I left the truck to idle until the “A/T check oil” light starting flashing due to being to hot, I turned off my truck and plugged in my scanguage2 and it read 114°f. Toyota manual specifically states to check the Trans fluid temp in the 97°-115°f range and I was honestly surprised to see that the temperature matched so precisely with my scanguage2 and on the Tacoma’s on board “A/T check oil” sensor. Hope this helps someone who reads this. Then You don’t have to bother with jumping the OBD2 port and putting the truck into “A/T check mode”.

Excellent video. You have saved me a lot of money. Thanks

Don't be afraid to drop the pan and change the filter too! With the filter I got ~5.25 quarts out. Filled with just over 5.5 quarts as my transmission was also low from the factory.

I am so glad you did this video , others I have watched seemed a little unsure about what they were doing

I love these kinds of DIY videos. I can't wait to see the next ones!

Thanks again for this tutorial and your time…very informative and makes me feel a bit comfortable doing it and my boys as well who likes working and tinkering car stuff. Especially when we got ourselves our second and a bigger 🌮 this time🤣😂

Hey Brian, great video. Nice tip about ordering the replacement overflow plug. I appreciate your transparency from beginning to end. It reminds me of some things I have encountered doing regular maintenance.

I’ve been waiting for you to do this, my Tacoma 14 only have 50,000 mileage, I bought it brand new. Thanks for this video.

Have an 07' 5 speed, but enjoy all your videos. 👍👍

Thanks for this tutorial! My 2015 is just over 60K so I need to do this. I will order the replacement bolt for the check/fill, great tip.

I've found that tapping bolts with a hammer helps to break them free/loosen them prior to using a ratched or hex.

I have the Toyota trans fluid ready and I've been waiting for you to put this video up. It's that damn temp check mode that has kept from doing it.

For Africa and Asia, the procedure is the same for the Fortuner and Hilux 4.0v6. The only thing is that the Furtuner does not have the A/T Temp mode (no such lamp on the display cluster), so I drain, fill with 4 litres, and open the overflow after at least 20 minutes of idling.

Great video. And thanks for linking all of the tools and products that you used in the video.

Great tip on replacing drain bolt & on refilling while truck is running- not found on other sites, please make a video on changing drain pan, would appreciate it!

Lol I have the same shirt. Born to ROAM! 😄

the drain plug. has a magnet on it to catch metallic chips so there is some. difference between the two plus other than one a hex bolt and other being a Allen wrench headed bolt

Waiting on the spark plug video. Your truck looks great

Hi, I think I miss the part where you use the clip or wire, (as jump) once you finish to change the oil (is this process a "must do", or can be skipped?), as well, to warm up the transmission in the finish process, should be in "Park" or "Neutral" position? Thanks for your time.

Your the master of repair videos! Great idea on swapping to a better plug, I did the same with the front differential drain plug, as mentioned in your video. Use the drain plug from the sister company Lexus, they have a hex bolt version in their world.

Just did my 06 Tacoma. Dropped pan and replaced filter and gasket. Fluid pretty dark but still some red left. Probably never serviced. I have to say with fresh fluid, this thing definitely drives smooth and the shifting is noticeably improved. I did find a rear output seal leak. Small but that will be my next repair....

Thank you :)

Nice and detailed. As it should be.

All you have to do is check your manual to see how much your initial fill amount is, meaning how much should be in your pan when cold. Mine is 3.2qts .2of a quart is 6ozs. so 3qts6ozs. When I drain mine cold a little more than 3qts. drains out. Then all you have to do is fill the pan with that same amount. I do this every 15,000 miles and fluid stays clean, never any problems on my high mileage 2013 prerunner

Crystal clear and detailed instructions! Keep it up man 👍

the subliminal picture had me cracking up

Nice I need to do this, was waiting for you to do this. Tekton is solid tools!

it is best to drain and fill, drive for a few days and drain and refill again.

I was reluctant to drain the tranny fluid on my 04 tacoma which was dark brown with a ever so slight red tint. I siphoned 2 quarts out through the dipstick spout. I refilled it with toyota dexron lll and now it shifts much smoother. Total cost: $57 vs. Toyota dealer at $349 just to drain & refill.

Im dumber than a rock and drained the transmission pan when i meant to drain the oil pan for an oil change. Just drove 150 miles over the weekend and finally realized that i really f**ked up. She still shifts and drives though, no codes on the dash. Guess I’ll fill ‘er up tomorrow. Thank you for the info!

Nice video but just a note: According to the Car Care Nut ( Master Toyota Mechanic) He states to remove the jumper after the car is in temp ck mode. Then check for proper fluid level. This is done to ensure proper idle speed when checking fluid level.

I know you did this video a while ago and I am going to attempt it now. I have a 2015 Tacoma SR5, 6 cylinder, 48,000 miles. My question is when do you remove the paperclip? Do you remove it after you are done with everything? Do you remove it when the engine is off or when it is running? I am 65 and this technology makes me nervous..... why couldn't Toyota just leave the dipstick in for an easy drain and refill? Thanks for your videos.

Thank you

Thank you good sir. Your tutorial and guidance is much appreciated.

Been waiting for you to do this. Thank you!

thank you very much

Thank you ,you saved me from a $400 tow.

Just came back from the nearest stealership here in MA. Plug switch out, 2 plug bolts, 2 crush washers. $26.59.🤬

I have a manual 3rd gen yet I'm still watching this

Just hit 200k doing this soon! Thanks for the video.

I added my transmission fluid through the radiator transmission line!! Surprise to learn that there is actually a fill plug🤯

I did mine a 19 V6 sport and I did all the checking level thing I found that if I drain the fluid and pump out as much as I can get out of three quart bottles and leave the little bit in the bottle that I can't get the pump to suck up that is exactly the right amount for mine it did anyway so that's great I don't have to do any of that checking junk anymore

Damn bro I have a 3 year old truck with 66k miles on it 😮

When/where did you use paperclip?

Thank you for your information very helpful

15/16" socket should fill the need for 24mm socket.

That's an excellent example of why you remove the fill plug first make sure you can put fluid back in can you imagine if you would have drained first and then realized you don't have the tool to get the fill plug out now not only are you waiting on the part but you don't have your truck anymore

Tekton tools are badass man! Made in America and reasonably priced!

lol @ the "peeing" audio for the fluid drain.....nice touch.

If you are doing off roading, try out Amsoil Signature Series Gear lube for your diffs.

Thanks for the video. So, to be clear, is the purpose of putting the truck into the "AT Temp Check" mode simply to have a way to verify when the transmission and fluid are at normal operating temperature? Thanks

You Did Not Use The Jumper Wire ? You Dont Really Need It ? Thanks ...Great Video ..

Good video!

Hi what happen if i dont jump the obd?

How often should your transmission fluid should be changed out?. Have a 2014 with 56,000 miles have yet to do it thanks!, 🤛🏻

What if the oil to tramssion has never been change it has 55000 miles

At the start of your vid, why do I have to master the trans temp check beforeI start ?

I tow a 4K lbs travel trailer mostly with my 2015 Tacoma and rarely drive it for other uses. How many miles do you recommend doing this service? I already have 35K on it and want to make sure it's in great shape for each road trip going forward. Thanks for the vid.

Great vid! Looking forward to a front diff tutorial, if you are feeling up for it. :-)

Hi accidentally drained trans , got 2.75 quarts out , Can I just add that amount back in ? Without worrying about temp check ?

Would you happen to know what the TEMP is supposed to be just to double check with a temp gun on the pan? Thx very much

Your Tacoma has 10.5 quarts of transmission fluid. You have to do multiple sessions of draining to get it all out. The factory did just fine lol

Thanks for the video! when you check the oil level, do you do parking, drive, reverse?

Thanks for the content! Question when you decided to add more transmission fluid after the first check why did you have to wait for the truck to cool down?

You went shopping at Costco. Have the same shirt.

Good instruction, THANKS ! Question, how do you put it into : "A/T TEMP MODE " ? I have a 2012 Tacoma Pre-runner 4 banger

Nicee video! And great tutorial. Thinking about doing to my 06 DCSB with 160k miles on it not sure if it has been changed you think the mileage is too high for a drain and fill?

I have a few questions. I have 130000 miles on mine so should I just do what you did or is there a filter that needs to be changes along with the gasket inside the pan?

why do you need to loosen or take off the overflow plug first, i just dont understnad if youre draining it all through the drain plug anyway

Question I don't get any of it, after you refill it then drain it out again and not refill it?

Yes indeed a great video, I have learned a lot from your videos. I have a weird problem with my Tacoma. Ever since I had dealer change the trans fluid, when I turn right fast the trans will not shift into next gear until the rev get up to 3,000 rpms. I think they did not fill completely so the sump pick up dries. Your thoughts??? Appreciate comments,. Thanks

So when the temperature is correct anything that comes out from the overflow plug is telling you that those are the excess fluid? When you first open the overflow plug you only had a few drops trickle, but he second time you had a whole bunch of fluid pouring down.

Wonderful helpful tips and guide. I have a 2018 Toyota Tacoma SR5 3.5L V6. @ 36,000 miles I have a question and wanted to know if the same things you use work for mine as well or should I get a different kind of oil? Second question is what kind of transmission oil fuild do I use to change and what other things do I need to change also? It's hard to find real loyal mechanics so I came across your channel and hoping to get some help all the way from: Juneau Alaska

I drained my transmission and added 5 quarts oil extra to engine and ran it for about 90 to 100 miles now im trying to fix it.

How many drain and fills did you do? Your ATF is super clean

Did I miss the part of the video about you needing to use a wire for the obd2 port?

So using ws you must have a 4 speed

What part number is the rubber o ring for the fill plug?

I got a 08 that i own since 2015. It had 91000 miles on it now at 250,000. As far as i know it never had fuild changed. So when is the mileage that transmission fluid should be changed?

Can you please explain the jumping of the OBD port with the paperclip.

Brian, Its time for my 2011tacoma to have its transmission fluid changed. Not so pink any more but not burnt. What are your thoughts on pulling the pan to do the trans fluid filter and pan gasket whilenim already draining it?

Maybe hit those plugs with some brake kleen and pb blaster the day before

Hi can i have question. how many liter from factory? Should be?

If you drop the pan, you can get more fluid out. This means you can get more NEW fluid in. You can also clean out the pan. 😘

Of course mine doesn’t look anything like that and I can’t find the full plug anywhere because my trans looks absolutely nothing like this. Only has one plug rather than 2 and is shaped differently from every single one I’ve seen in dozens of videos.
