8 years later and this video is still bringing me entertainment and education. Thank you!

Hiram is the "BOSS" when it comes to KZfaq transmission videos - NO ONE DOES THEM BETTER. Most people who are employed as professional ASC certification instructors could learn a lot from this man when it comes to teaching and transmission service techniques. Compare this video to ANY other transmission rebuild/teardown video on KZfaq. You will quickly reach the same conclusion that I did years ago. This guy is clearly in a league of his own.

Great videos Hiram. I'm not a mechanic but you have a knack for teaching - and for properly filming what you're doing. Well done. I've learned a lot. Thx

I don't work on transmissions but I like watching your videos. You are as skilled and knowledgeable as I have ever seen.

If other folks making how to videos on KZfaq was as detail as this guy I could fix anything the first time around. One of the best videos I have seen made on any subject. Great job.

I'm astounded that he can remember how to get it back together,....great technician.

I plan on doing a 4T65E rebuild soon and this video is invaluable for the research process. Thanks for the detailed explanations and in depth disassembly!

Hiram provides more information than any service manual ever could. He is awesome

You're a surgeon with that impact wrench!!

These are people who specialize in one part of a car. Just as surgeons who specialize on one part of our body. So it's a cakewalk for them. Awesome video

muchas gracias sr Hiram por sus tutoriales son de mucha utilidas tengo 12 años dedicandome a reparar transmiciones automaticas pero no falta que se le presente alguna falla o duda con alguna pieza interna de la transmicion y sus tutoriales me ayudan mucho saludos desde Ensenada b.c Mexico,porsupuesto que estoy suscrito a su canal y miro sus tutoriales muy frecuentemente,espero que entienda español

In my humble opinion, this is by far the best video on all youtube

Dammit man, the automatic transmission is such an intricate component. My hat goose off to you for having the skills to do this.

Great stuff Hiram, I really look forward to your videos. Thanks for sharing your extensive knowledge.

Love these transmissions, and the W body vehicles they are installed in! I did the DIY shift kit on my 98 GTP, 2-3 accumulator spring in the 1-2 accumulator as well as a 3/4 steel spacer in both accumulators. Car had zero issues shaking the tires into 3rd when you were flogging it! Had good manners when just cruising as well!

Awesome video from a true professional. I would send my transmission here for rebuild any time of day. Way to go Hiram!!!

watching this video for a guideline for installing my aftermarket TEP build parts for my 2005 GTP Prix. excellent walk through. thank you man

Came here to see why my forward band broke. Got more than I bargained for. Thank you! INCREDIBLY HELPFUL.

The ease of your words and actions are wonderful, having an 01 Monte Carlo that is starting to have issues and knowing nothing about transmissions. After watching I now know that there are many types of issues that could be causing my problem and have a better understanding of why a professional rebuild can be so costly. Thank you for the insight.

I just finished rebuilding my transmission using your video. One of the best videos on KZfaq!

I am quite simply amazed at your knowledge and abilities! I have been working on cars for over 50 years off and on and had considered rebuilding my 2002 Impala 3800 transmission after the cooling fans quit and the transmission let me limp home at 10 mph in 1st due to the overheating.. After watching your video I wouldn't do it if someone put a gun to my head. All those parts you said not to forget-I would forget about half of them! I wish I had your talent.

This is an amazing video! Very nice contribution to the public sphere. This answers so so many questions! Getting ready to do all solenoids.

OUTSTANDING! Great job in sharing your expertise via this thorough, "basic"[?] teardown. Components and indication of their condition is terrific. Many thanks maestro. [Mine is a 4T60-E but very similar fundamentals of course.]

Videos like this make me very very happy. Not only can I learn, but you are clear, concise and know what you are doing. Surgical. Thank you sir!

U helped me much rebulding my transmission ( master rebuild kit + washers kit )( i recommend super master rebuild kit and also clean with diesel fuel all ) , great video, many "likes", clean video, very punctual !

You do great videos, so much to cover, I rebuilt a 700r4 with the help of your video, then ran into the situation of having to buy the $100 bore tool and updated valve for the tcc lockup issue because the bore was worn and the original valve was prone to wear out because of its size, because of that valve I still had issues with the valve leaking causing slippage which was what caused my transmission to fail in the first place. While I had it out and torn down I also installed the trans go upgrade spring kit and had to replace the plastic servo pistons with aluminum ones to prevent future issues as you noted in your video. I also I installed repair grommets on the valve body plate where the check balls wear out the plate. The transmission works better now than when it was new. Been going strong towing heavy loads for 3 years now with no problems. Trial and error and patience is a learning process but it helps to address every known issue before you rebuild and have those parts ready. After all with all the work involved you want the trans to last. The problem with all these transmissions is you are not just replacing seals bearings and clutch packages, there are numerous parts that had design flaws that needed upgraded part replacements like the sun gear issue with the 700r4 you mentioned in your video which I did replace out of caution even though it looked okay. I find you have to do the tear down, inspect every part carefully, research every fix and upgrade so while it is apart you can get all the needed parts to address every design issue to prevent other possible problem in the future because of the failure of the factory original non improved used parts you reinstall. In this video you did not cover much about the issue with the valve in the plate which is a common problem, I believe it was the modulator valve, I understand there are 2 fixes for it, either boring it out re sleeve it and put in the new valve in the kit, or superior offers a k-098 kit to address the valve leakage issue that does not require boring, it uses a plug and new valve

Your vid gave me the know how to remove the rear cover to inspect and test the sensors and wiring inside the trans, to bad the hard part is dropping down the sub frame to get at that cover. Thank you from northern B.C.

Excellent video. Very instructional and informative. Thanks Hiram!

This was really impressive to watch. Thanx for posting.

Thank you for this great video. I wanted to understand how the transmission works and your video was excellent.

I want thank you for our time. Learned a great deal information from you.

Wow, I could never do this, found this video by mistake, just wanted to replace my trans fluid filter, but, enjoyed watching you work so much that I watched the story all the way to the end. Thank you Hiron, excellent works.

I wish guys like you were more accessible . You are very helpful and we all have so many questions lol. Thanks for the vids.

You're too awesome dude! You've helped me a lot with these trans units. More CVT(s) :)

I am thrilled you got one of these units to rebuild. I wish it happened earlier, back when I was rebuilding my own 4T65e-HD unit. You have covered a few details not included in the service manuals or the updated technical specs manuals. Information that would have saved me some time on the build and a lot of time on the intensive research I did. My 2nd clutch pack had the excessive play - I was unaware the steels were available in variable thickness at the time. I tried the trick of adding one of the original steels to the assembly, but the tolerance was too tight. Without it, it was too loose. I played it safe and went with the too loose option. Since the rebuild, my transaxle still runs great to this day. I have the occasional 1-2 long shift issue, but it's a rare thing. The MAX ADEPT (not max adapt) code gets flagged when it happens. The updated spline drive was implemented in 2004 BTW. I made sure to get that part. I also added the clamp for the accumulator lines. The one thing I wanted to try, but didn't have the detailed information for is this trick.. Adding a 'squirter' line to the differential. I've seen this done on a forum somewhere and it caught my interest. GM has a high performance rebuild manual for these units too. They use only 3 forward gears instead of 4. GM also produced an upgraded input shaft that retailed at $1,200. This part is no longer available. It was designed without the groove for the O-Ring, the first thing you removed in this video. Another company makes a high performance input shaft for around $600. I couldn't justify that cost as it is more than I paid for all the replacement parts from my local parts supplier. I also included the transgo shift correction kit and a re-manufactured torque converter. I must say - I really enjoyed going through the process of the rebuild and the research involved to get it right the first time. Well, almost right, minus that intermittent long shift issue. I found your videos to be most helpful and I can't express to you how much I appreciate your feedback when I hit you up with my questions. Hiram, thank you so much for sharing your skill with us! You are an amazing technician and your video's are an awesome learning tool that provides an excellent supplement to the tech manuals. I hope you have been able to share my southern engineered J-Tools with a few people who don't have the real deal. One of these days, I will go through all the photos I took during my rebuild and make a good video to share. I need to add the engine rebuild and the other special modifications implemented along the way. In the meantime, I have uploaded a few locksmith and security videos on this channel if you have any interest on that subject. This one is my favorite. It may be old, but it has great info that still applies to this day. -- kzfaq.info/get/bejne/rruPY7KH3s2pfY0.html Thanks Hiram - you da man!!!!

OK Hiram you delivered!! I asked for a 4T65E video and here it is. Thanks a bunch. My personal feeling is that this is one of the best automatic transmissions ever made. I've had too that have gone over 250,000 miles each. Always love to watch you work. Looking forward to the additional videos you must have in the hopper on the reassembly of this unit. Once again thanks.

holy shit this thing is more complex than the space station.

Excellent vid of the 4T65E rebuild process and known issues. I just blew 1800 clams on my 2002 impala tranny overhaul; it had multiple problems including a nearly 100% stripped 4th shaft. Thanks for your channel and insight. :)

Thanks very much on this breakdown of letting me know everything and how something can be reusable or wear down..PERFECT

master builder for sure,glad I'm retired,i did this for 47 years,these people are in good hands with you still building,you are definitely a super wrench,hang in there builder

that is the most awesome trans video I've ever seen, and in the top 5 best how to vids of any topic. great job. thanks for taking the time to post it. regards

All my cars have the earlier 4t60e. Thanks for the vid.

I'm not even working on my transmission, but enjoyed the video so much that I'm subscribing!

My 05 lesabre needs this done. Best video ever very thorough. Thanx for the video I just liked and subscribed

I really appreciate the detail and description you go into for this video. Thank you!

I have this transmission in our 02 Bonneviile, I looked the world over to try to find the neutral safety switch on this car, hummmmm its in the bloody transmission, kinda hiding in there, hahahah It didnt start once or twice, I changed the crank position sensor then started looking for the neutral safety switch,,,,thats when things got funny...Thanks to your video, I plumb found it...lol thanks bro...

Great video !!!! And great memory to remember how to put back all those things together!!! To me looks like it a lot of it! But l love your video l got the same transmission on my 2002 year Buick rendezvous .!

Your knowledge is amazing.

Thank You so much for your valuable information showing all and talking about the transmission and parts. I subscribe to your channel. 😊

Thank you Hiriam. I found that forward band bit, which you said breaks frequently, in my S80's pan. I know what to do now. Also it does move slowly in manual 1st, 2nd starts flaring, exactly as you described.

Dam he's fast! Totally on point!

This is so raw! lol love to learn. Thanks a lot, hope I can teach others a craft too, ppreciate it

Wow I feel like I can fix my transmission myself after this video very educative thank you

@3:40 Broo, the answer I was looking for. You are a great person and the king of the day!

I know extremely little about transmissions but I do like watching someone work who knows what they're doing.

outstanding as always Hiram. good video

Great video Hiram.Nice to watch a professional doing his thing.😎👍

that is how my 08 impala blew up. That forward band piece that you pointed to in the video was in the transmission pan. I knew my car was done then and like you said you may get movement in 1st, 2nd at most, but there is no forward movement. I also lost reverse too during that time.

wow the transmission is indeed one of the greatest wonders ever created by the human mind.

Thank you so much! Would love to see a 4T65E full rebuild!

You know he’s knowledgeable when extra parts and springs on the slab does not mean confusion.

Thank you, you did it well.Very well desassembly and explained too.

I worked at the plant in Warren Michigan that built that trans. Worked as a wet line repairman for a year or so before they went E . The first generation were 440T in about ‘83/‘84

great video thanks for sharing top quality as always

I can even get a headache by watching it, let alone doing it. So professional

Fantastic video. This is going to help me out a lot. Thank you!

Most definitely the ConNewton valve that’s connected to the flux capacitor looked worn lol That’s why you do what you do good job.

Great video! You were very thourough. Fantastic work.

I’m no professional, but my 4T65E-HD GTP transmission began to fail at about 150,000 miles. Main things replaced: clutch internal and external rings with teeth(some broken), reverse servo bands that squeeze the clutch I believe were somewhat burned, 4th clutch shaft (splines were stripped halfway down), chain scoop was replaced, transmission mounts, main control valve body, internal harness, sonnax actuator feed limit valve, pressure control solenoid, 3rd clutch spring, 1st and 2nd support bands and torque converter. Some small things were replaced also but that’s most of the big stuff. The transmission now runs great.

This is both terrifying and educational lol Great video, thanks :)

Awesome job. Thank you for sharing

very nice video Hiram always looking foward for new ones!!!!!!

you're the man !! learning a lot !

Glad I found this. Very informative. Under heavy acceleration in my 01 silhouette, I get smoke, which is burning trans fluid. Never any fluid leaking on the ground. I think that breather is right under the exhaust crossover. Makes me wonder if that paper gasket is torn.

Damn no wonder it's so expensive to get a new transmission or get it rebuild

HIRAM YOUR A BAD DUDE. KEEP UP THE GREAT WORK BRO.....THANKS GOD BLESS

Awesome video man so informative and so well done best video ever

Good video thanks for sharing very detailed. 👍

The transmission fluid is the life blood of the transmission After watching this I'm gonna drain mine every 10000 miles

Thank you very much .Sir.I`m learning from you,sir.You are great.

Thank you the extensive tutorial, I can see you’ve done that before. My tranny sometimes has no forward or reverse after sitting a spell, shut the car off once or twice and it works fine. To me, it seems electrical or valve body problem with no codes. ....It’s an overhaul. And after watching your video, I’m not getting into it. Thanks again I enjoyed it.

Just watched his video on tear down of a transmission wow he knows his stuff!!!👍

Impressive. You sir are a transmission doctor.

Definitely awesome professional technician Great experience and excellent explanation best regards

Done work on these. They can be very troublesome if you're lacking the experience to work on them. Mine is a 4T65E HD. They were mated to 3.8L engines that had superchargers on them and also the 5.3 V8. The HD version has a stronger final drive and the CV axle input is larger on the passenger side

Great video well explained, Thumbs up!!!!

you really do a great job with out hesitation in your word my first time watching

Impressive...most impressive. Subscribed and thumbed up!

Always have just the info I need when I go inside, it's been 10 years since I left a trans specialist, and I'm getting too old to remember everything, thanks, Hiram !

That was a great video thanks so informative

damn this is good at explaining this break down in pretty good detail how!

Incredible video. Sir, you know your stuff.

A transmission is the most complicated thing I’ve ever seen. Somebody who can pull this apart and repair it is above average intelligence

I have a 2005 chevy impala, 3,4 motor 4t65e tranmission. It pulls but is very slow at shifting ,an acts like it doesn't want too shift from first , but if you drive it easy and give it about 3 too 4 seconds it will shift, it does make a funny sound for about 1 second and then it will shift too all the rest of the gears, an go really good , I change all new solenoids and still does it. It shows no engine codes .

Those three he mentions as very tight, that's an understatement. I had to stick a bike seat post on my socket wrench to bust them loose without damaging anything. Probably best to measure the bolt lengths if they're that tight, they can stretch and that would be bad.

No wonder those things are so darned expensive to replace, and fix :D Stick with the stick shift :D

Nice work bro he did really good i do this like evry 2 weeks on cars lol

So good to see a real pro, good job! There is no way I can do this and I am a handy man with cars lol.

not all heroes wear capes. you deserve to be rich and live in paradise friend

you make it look so easy :) I don't need an introduction on this trany but dam it was so entertaining that I had to watched this whole video nice job I'm impressed thank you
