4L60-E Transmission Full Rebuild 

My mom said, 40 years ago,watching tv would rot my brain. My wife said,10 years ago,watching RU-vid videos would rot my brain. I'm not a mechanic but I rebuilt my ls engine last month and now rebuilding my trans this month...all Thanks to RU-vid videos by true professionals like this. Thank you Hiram for sharing your time and knowledge.

This is a master piece on RU-vid. I can claim to have repaired my transmission by following your instructions. This is now 5 years later.

I am a complete amateur, not a mechanic never have been. I followed your video step by step and to my amazement the transmission works great. I'm impressed with myself, but far more impressed with you. I've been telling everyone about your video, and I cant thank you enough!

i quit wrenching on vehicles professionally after 13 years, and watching this makes me want to rebuild 60e's part time, it looks like a really enjoyable puzzle

I'm jealous of the knowledge inside this mans head.

I was 16 years old the first time i opened up an automatic transmission. I remember thinking that this thing must have been part of whatever crashed at roswell. 30 years later after watching your video , I opened up another one and successfully rebuilt it thanks to you. you are truly a master of your craft

The automatic transmission really is a marvel of engineering....I would never attempt this sort of work but I really respect anyone like you that can. I just enjoy watching someone who is really skilled at their craft operate.

I don’t think I’ve ever been so impressed watching a craftsman perform his craft. This is not just memorization of some service manual..This is the result of many years of experience and work in the trade. Respect.

My Dad rebuilt transmissions in his shop that he built over many years in our backyard. He did this after working his regular job all day! He started when he was 14. He only went to 8th grade. It takes years & passion. Now my son is driving & his truck has a 4l60e and its slippin in 1st & wont reverse. Sadly my Dad passed away in January 2022 so we dont have anyone to rebuild it. I hope your video will encourage my son to maybe pick up his Papaws hobby & try to rebuild his transmission. Thank you sir. I know the hard work that goes into rebuilding a transmission. I always wanted my Dad to make a video like this.

Being in the Auto Parts and Auto machine shop for 60 years. Your expertise is appreciated.

This man is a master at his profession, if I knew my transmission was handled with this much care and rebuilt with this level of expertise I would not hesitate at all handing over the cash! Thanks for the video I didn't even realize it was over 2 hours long till the end I was so damn intrigued 🤣

Rebuilding an engine seems like a walk in the park compared to this. Great job man. You deserve a lot of respect!

Sir, absolutely a great video. No BS, straight forward video with great detailed explanation and process with important warnings... really appreciated the hard work and effort put into getting this to the masses. Thanks again!

Hiram= Jesus.!!! I know nothing about transmissions but I watch every minute of this man working like a surgeon. Wow!!

Master of transmissions, he took it apart like he changed the batteries in a remote control

Hiram, I just wanted to drop a note to say thank you. I've been a auto hobbyist my entire life and have rebuilt every piece of a vehicle except for an automatic transmission, until now. For some reason they were always a little scary to me. Thanks to your detailed video and great verbal explanations, I finished up and drove my first 4l60e rebuild yesterday. I had to stop and rewatch some of your segments to make sure I was doing things correctly, but the entire process went very smoothly. I even installed the transgo kit you detailed in the other video. The trans drives and shifts perfect. Thank you again for all of your time and effort put into making these videos! What a great feeling to successfully rebuild my first automatic transmission.

You, sir are a true professional. You cut no corners, make sure that everything is right, every potential issue is dealt while the unit is on the bench. So many half-ass transmission shops out there that take your money and do as little as possible. Then the thing fails again in short order.

Absolutely amazing how people can have such knowledge in something so complicated. Wow

Note to Builder: Brother I came up thru the ranks from R&R man....Shop foreman,The Builder..eventually center manager.There are videos here on YT of a "Transmission EXPERT". His expertise seems astounding to some guys,He quotes some things about units. It's ALL RWD, No Front wheel drives. NOTICE NO VIDEOS OF HIM BUILDING ANYTHING Except a THM350,a very simple unit to build,yet they whoop&holler how great he is,Just had to say something,I built transmissions about 35 YEARS,This channel this man builds,not just teardowns,Thank you Brother Transmission BUILDER!.

Truly impressive. Never again will I complain about the cost of having an automatic transmission rebuilt.

This man is a genius. Just the thought of rebuilding a transmission gives me goosebumps.

From one technician to another I appreciate your videos, every now and again I work on a transmission and I will get the service manual but not always will you get the true real world experience that you hear from a tech that has seen it done it, I find my self watching your videos before I start to disassemble it because you have an in depth knowledge of the individual transmission.

I just glad people like you are willing to take the time to make videos like this. It's getting so expensive to have the work done and at least this helps someone who wants to save money and learn how to do the job themselves. It also shows how much work and time goes into it so we understand why the shops charge what they do for job. Thanks for the video.

Needing a refresher after 20 years since I worked for a short stint in a transmission shop, and getting ready to tie into a long lost friend the old 4L60E. This gentleman is truely a teacher that deserves alot more than 21k likes, considering almost 4 million views. subscribed and liked!!!!!!! Thanks for all your help Hiram!

Also thanks for being there and for being available for help it definitely means a lot for us technicians that need a little help we're all in it together. I hope to see more videos from you because I don't see you missing anything but being extra careful to explain everything THANKS AGAIN PAUL TAV 👍.

I just witnessed magic. I enjoyed watching this. I have no desire to rebuild a transmission. You've earned every dollar you have. Salute!

Its been years since i first saw your videos on rebuilding transmissions, as a young shop tech i watched them to gain more knowledge on a system i didn't know, and found your videos very informative. I had my transmission go out recently, 23k miles after a rebuild and here i find myself watching your videos again but this time with the intention of rebuilding it myself. I really appreciate your videos and you sharing the knowledge you have gained along the way. The fact you know so much about your craft and how you share your wealth of information is incredible. I'm sure there are many others who have found your videos as useful as i have, and i just want to thank you for your efforts in putting the time to make all these videos.

You are a true Transmission god, and I kneel before your greatness. Thank you for confirming why I would never tackled my own transmission. Amazing video presentation.!

This man speaks from so much experience. Absolutely incredible video! This should be mandatory for people who work in shops to watch!

It has been a little over 40 years since I rebuilt a transmission, so I watched this to learn about a more modern transmission. The last transmission I worked on was when I put a shift kit in my Cadillac TH400 that I install in my 57 Chevy. Man that was a long time ago. Thanks for the video.

This is a damn wonderful video. Super helpful, and you can tell this person really knows their shit.

You are a Master my Brother, I dabble in all parts of my cars/trucks but when it comes to transmissions I know that the rebuild is very complicated. Thank you for the insight but I'll leave the trans rebuilds to the pros like you. God Bless.

me full of ambition: I'm going to rebuild my transmission. *gets on YT watches this video* *two hours later* me: googles nearest transmission shop

Thank you for taking the time to make this video, my granddaughter and I learned so much from you.

I have to say they don't make many people like you. So many shady people out to get theirs screwing people over. You sir have the attention to detail, knowledge, professionalism and most of all unselfish sense about you. Thank you for sharing it has helped me a ton on my h3 where I have already been screwed over several thousand dollars. thank you.

Hey Brother. Your rebuild video is the most thorough help video I've seen. EXTREMELY HELPFUL! Keep up the good work. 👍👍😎

Customer: I would like my transmission rebuilt. Hiram: Have a seat in the waiting area

by the first half hour i was sick to my stomach man lol.......this is ridiculously hard to do no one knows...... your an expert man keep up the good work!

Not that I would ever try to rebuild a Trans But you make it look so easy Love watching you work One of the best Video's I have seen on Utube This is what Utube is all about people like you Great job

Truly a pleasure to see a professional working his magic and doing the job correctly with the right tools and superior knowledge!

This guys like a transmission surgeon. You can tell he knows what hes doing.

when somebody is good at something they make it look easy

by far the best vid from someone who knows exactly what he is doing,,thanks for your help and I will be watching more of your stuff

I am just happy there is some honest and knowledgeable mechanics left in this world.

Thank you sir very much for taking your time to show me your valuable knowledge im looking foward to rebuilding mine now looks like a hectic situation but having you along the way makes me feel more confident in the project

Hiram... I can't tell you how ecstatic I am about this video. I generally do a lot of my minor mechanical work such as oil changes, battery replacement, alternator, water pumps, serpentine belt, throttle, radiator, brakes and rotors etc.... However just last night I thought pretty soon I may have to do something about my transmission and having a limited income I always have to find the cheapest but most reliable route to get the job done. So I decided to look on RU-vid as I always do and search the internet to see what route I'd take. Lo and behold here you posted a video only days ago that support my future need. I have a 2003 Escalade EXT. I love working on my truck 1. Because I save a lot of money 2. Because I make sure it's done right 3. I have no one to blame or be mad at if it isn't 4 The shop mechanics can't beat me...lol. Anyway as I plan to embark on this journey to my first transmission drop and rebuild (which may take some months, I think I still have a significant amount of time but I'm still planning) I've run into a bit of a roadblock in my preparations. The transmission model is't engraved on the case. So I did some research and I think it's a 4l65e but need to be sure because once I drop that bad boy I won't be able to run back and forth to the auto store without inconveniencing others and I hate to do that. anyway I did find a number on the transmission that helps identify my transmission on the bottom at the end of the pan. The number is 3KZD4 042A 35523509. Also do I need to replace the torque converter and the transfer case, after all I have a bit over 202000 miles. I sincerely thank you from the bottom of my heart for sharing your skill for those of us that need the help...... If you or anyone else can answer these questions I would greatly appreciate it. Subscribed!

Thank you so much for this video man. You're an awesome teacher.

I would hate to even think of paying someone to do all this! He is so good, thorough, and clear in his explanations.

Thank you for the video. It was an amazing help in rebuilding two 4l60e transmissions. (One in a 2001 Silverado and a 1996 4l60e retrofitted into our 1965 Impala.)

Man just wanna say I love how much detail you put in this video it’s perfect the best video I’ve seen yet learned a lot from it

And this is why I need a transmission guy. lol great video

Having coffee on hand is an important part of all Automotive work.

These guys earn every cent they make

What a great service you offer to the viewers. I retired from the new car dealership as a service advisor after many years as a line technician. I handled all the transmission repairs for a dual franchise Dodge and Buick dealership. I definitely seen my share of overhauls from rear wheel and front wheel drive cars and trucks. It's a dirty job with a lot of parts cleaning and labor intensive. You have an excellent work ethic and fine presentation of skills.

This is what I call a profesional! God bless u & ur family!

Wow you sir are very fast and pro at rebuilding transmissions 👍👍👍👍👍

This is one of two of the most informative videos I've ever seen on YT. The other was from ScannerDanner. Hiram is da' Man.

Watching him disassemble this, I didn't think he was ever gonna stop pulling stuff outta there. I was waiting for a kitchen sink to magically materialize. I could probably find a way to tear one apart, but getting it back together, now THAT would take a small miracle for me.

I bet $1000, this guy was freaking amazing with Lego's when he was a kid.

Just wanna say you are the professional one ☝️!!!

Thank Brother you're the best at what you do

Calling you the master tech would be an understatement, I just wish you where my neighbor or my best friend.

Tank you,I have,learned a lot from Your vídeos, they are real lessons GOD bless you.

As a DIY mechanic I started working on auto engine rebuilds at around 12 y/o learning from my dad. Years later I bought a used ‘68 Camaro 327 CID that needed an engine rebuild and I decided to also try rebuilding the simple 2 speed powerglide automatic transmission....what an eye-opener!! It took me 5 times as long to rebuild the transmission as the engine, but I did manage to figure it out. Years later I decided to try converting a 3 speed manual Mustang 289 to an automatic, by buying a junkyard Ford C4 transmission, bench rebuilding it and installing it. It was 3x more complex than the powerglide, but it was all mechanical and I managed to figured it out and install it. It was still working perfectly 100,000 miles later when I sold it. Many years later I restored an ‘85 Firebird Trans Am to all mechanical specs despite it having a 700R4 ECM-assisted transmission, which was way over my head. A local tranny shop friend bench rebuilt it for me, removed all the internal electronics and installed a mechanical shift kit which to this day still works perfectly. Now I have a ‘99 Tahoe with the older version 4L60e similar to the one you just rebuilt. Despite a hard 1-2 upshift (from brand new), the tranny is still perfect (only 63,000 miles on it). While I’m too damn old (75) to undertake another transmission rebuild given the incredible complexity of these incredible computerized transmissions, guys like you make old fart DIY mechanics like me wish I was young enough to give it another go. Beautiful job, superb knowledge base, and excellent videography.....I savored every minute! Dr. K.

Yup so ima need a transmission guy .I thought I could fix It myself but I am wrong.Great Video 👍

Mr. Gutierrez, you are an awesome mechanic sir! My transmission is in an '87 Chevy S10 pickup. It's very similar. I've got most of it taken apart now. I can't find the snap ring for the sun gear, but I'm sure it's there. Thank you!

you get a standing ovation for this one sir. Great video On a side note; seems most videos RU-vid keeps suggesting would imply employee mindset not an employer mindset. Wonder if I'm the only one??

Hello it's 2023 your video 10 years old your information is still as valuable as the day you made it I'm having problems with my transmission my '08 Chevy 4 speed The parking paws hanging up doesn't allow me to go into gear from park lever shifts with no action seems like it wants to go into gear I go back and forth with the shift back and forth back and forth finally it built enough pressure to pop it free When It goes in to gear the truck drives fine has a lot of mileage on it your video and many others that are out there have been very helpful to me thank you for making these much appreciated Bill Western Mass USA

Thank you, Thank you for this. I have been able to successfully rebuilt my transmission and now currently working to rebuilding one with performance upgrades. Knowledge is powerful and your video has given me that.

The video is too long and that’s why it is awesome 👏 a lot of excellent details.... thanks a lot dear .... subscribe and like for sure 😍😍😍😍😍😍😍😍🇯🇴 Saed from Jordan

Every time he left the screen he was getting coffee. When you rebuild one of these you need to consume as much coffee as transmission fluid that is in the transmission.

Give my teacher some more coffee. 💖

Wow what great reviews been a mechanic all my life never opened a automatic was told it was rocket science so I steered clear allways r&r til now I found this video and reviews and opened my first one....

This is my first GM transmission rebuild. Actually I'm repairing this transmission for my uncle after the last rebuilder left the plug on the B shift solenoid unclipped. Made it 7k miles before burning up the 3/4 clutch pack. Had a serious vibration at about 1,500 miles. We thought it was the rear axle as the truck has 525k miles on it. The rebuilder's health got really bad, so I decided to find the problem and repair it. But it's not terribly different than the Ford's I've been into. I'm at repacking the 3/4 clutch pack after pulling the complete transmission apart and washing out the burnt fluid and clutch disc material. Great video for those of us who dare tackle a transmission rebuild.

Did that Scare the Shit out of anyone else?

This is like watching a heart surgery.

Damn, I hate to take mine in now. I can just see dollar bills flying all over the place. You know it's not too bad to pay for a repair, it sucks paying for a poor repair.

Hiram is a true master of his art and a great teacher…always explains everything clearly and to the point…legit love watching your vids brother.

Cheers for taking the time to show us all how to work on transmissions inspires confidence.

Now I see why it’s costing me $1,100 to fix my transmission.

very informative and very thorough.....nice job on parts, bushing removal, and installation as well as breaking it down and putting it back together......thanks again Hiriam are you on the west coast or east coast?

You might want to reupload it in 30min. vids. Audio gets out of sync on long videos like this. Also I would like to see a rebuild on a 94' 4T60E.

Thank You my Brother! You helped me rebuild one that I cooked... Couldn't have done it without your knowledge. Many Blessings on you and your family!

Wow theres 50,000 parts and this guy knows all of them by name where they go and what they do, how do you remember all these bolts and springs, seals. Man this is just mind boggling how smart this guy is. Sir I take my hat off for you, and now I also know why this repairs cost so much. Thank you so nuch for this video I surely appreciated it.

Hello Hiram. Thank you so much for sharing your knowledge and experience with us. I used your video to do a complete rebuild on my 4L60E and it now works really well. I do have a question though on the TCC I was hoping you could help with: It doesn't engage. I tested the solenoids and can hear it clicking in the gearbox when I switch it manually (I wired it directly to a switch to check it). I had the torque converter cut open seals etc replaced. My question is - do you think there is a chance there could be an airlock in the TCC circuit or something else causing the converter to not work as all the mechanics and electrics seem fine? Thanks so much again for the great videos.

Skilled guy, but with all those old parts laying in that back tray, it would be a real time waster to have to dig through it all looking for an errant circlip or other small part.

13:08 - I nearly jumped out of my skin.

Thank you so much! I have a 1998 4x4, 2500 with vortex motor 5.7, your presentation will help me figure out my transmission as I haven't had reverse for 1 1/2 years now. presently I'm rebuilding the front end. New rotors, hub bearings, lower ball joints, idler arms all with adj sleeves and pitman arm. My truck is a SILVERADO.

Wow, like a skilled surgeon well versed in anatomy you expertly dissect each component and describe, in detail, every part’s use, condition, and interrelationships to other parts. Phewww, I was lost just after the bell housing removal.. Great job! A real professional …!!

Hiram, where are you located?

help me auto rebuild jaun your my only hope

Seems like Chevy ford dodges all have junk transmissions these days.

Absolutely brilliant! Nothing better than seeing a craftsman do his work with such speed and precision. Man I wish your business was near me.

I have a 2003 TB LT and a lot of time and $$$ invested keeping it on the road. But I like it and have learned more about doing some of the repairs myself than I ever thought possible thanks to videos like this on RU-vid. Well, 268,000 miles on it now and the transmission started clunking and slipping, and soon went out last weekend. I lucked out and found an incredible shop who had it rebuilt and replaced by Thursday. I was wondering what all went into this kind of job and found this. Thanks for an incredible fully detailed step by step process of what they did. So many little steps that make a big difference. I would never attempt, I'd lose track of all the bolts. But seeing what they did, for $2800 which I thought was a bargain, was really interesting. You don't get paid just for what you do, but what you know.

I'm mechanic and I learn with you a lot of things, thanks

Just another super big THANK YOU!!! for your time and sharing your knowledge. Six yrs later and you are still helping thanks to your vids.

Well guy's used this video to replace the trans on my 06 trailblazer...Just hit 54k miles and all is well...no judgement ment please lol but 5 kids in . We need the ole blazer and all 3 rows and TV's to keep the kids quiet...Videos like this save me thousands on a new tran & I truly appreciate the effort & Time spent...🧘🧘🧘

Sir I cannot thank you enough for showing me that this is definitely something I should leave to the professionals

Wow. You are impressive. To tear it down like that and know what everything does and where it goes. What a skill to have.

This is definitely the most complicated component of a vehicle. Fantastic video
