This is a basic video of an installation of a Transgo shift kit on a 4L60-E. This is not a performance shift kit, it is designed to address most of the common issues that this unit originally has and correct them.
Hiram, do not be overwhelmed by all the requests people make of you. Most are simply trying to learn as much as possible from the master. Yes, we know how tough it is to make these videos and we all appreciate your efforts in doing so which go far beyond the call of duty. Keep following your heart Hiram, you obviously have a desire to share your knowledge, and we clearly wish to learn from it. DO NOT GET DISCOURAGED!! As we golfers say: "You Da Man."
the skillled tradesman are getting scarces because of all the techy bullshit jobs,, we need this experienced class of tradesman to share thier hard earned knowledge. a person who learns a in demand trade, will always have money if they are go getters and not lazy or timid.,,. there will be 4l60s to fix for another 25 years.
You are correct about the secrecy of transmission building. Your videos got me through diagnosing and completely overhauling my 4l80e. So far I've put 70k miles on it and it still works perfect. I've also ventured into doing 6 different 4l60e's all thanks to your knowledge. Thank you so much Hiram.
Its so dumb to hide the information.....you aren't losing work because anybody watching these videos is doing it themselves anyway. So it's just being super selfish in my opinion.
Absolutely love this video. Wish there were more people willing to share information like this. I was on the fence between this kit and the sonnax kit because of the pwm valve, sonnax claimed their way was the only way to do it properly, because it limited the torque converter pressure to 100psi...it looks like this kit tackled the issue in the same manner. I was also worried about not being able to upgrade the boost valve since I cant down my daily driver to pull the trans. I absolutely love that you simulated the install as if it were in the vehicle and showed the boost valve being replaced. Thank you sir, you saved me a major headache and quite a bit of money.
2 years ago my '06 Avalanche had developed a flare in the 2/3 shift. I decided to go with this TransGo kit and whatever internet advice I could find (which was quite a bit). I replaced the plastic accumulator pistons, added the 'Vette servo and a couple other things using this (and other Hiram videos) as my bible. Somewhat to my surprise after I got it together and took it for a ride that trans shifted flawlessly! Nice firm (but not stupid hard) 1/2 shift, perfect 2/3 and 3/4 shifts. It's been flawless since and start to finish only cost about $140 and took maybe 4 hours. You ARE the King, Hiram! Thanks man!!
Thank you for sharing your time and knowledge. I'm sure other rebuilders are afraid to share their expertise for fear that people will begin to do their own transmission rebuilding. I have been a general technician for 47 years with some basic transmission knowledge and there is no way I would ever attempt to completely rebuild one even after viewing most of your videos. Please keep them coming whenever you can. I really enjoy watching a true expert apply their trade.
I had my transmission rebuilt a few times, then i got tired of having to remove and install it before i decided to rebuild it myself. Thank you for the video and for explaining so much in detail as you worked. Your video was excellent and helped me tremendously. God bless you brother.
Just wanted to say thanks for the video. It prompted me to go ahead attempt installation of the same Transgo shift kit in my 2002 GMC Sierra with only 52K. It recently started having hard 1-2 shifts and an occasional triple shudder on the 1-2 shift after highway driving. Thanks to your video I have a good working transmission and hopefully prevented any damage to the rest of the trans.
Thanks for all 4l60e videos you've done, you tought me well on how to rebuild a 4l60e. I rebuilt my 2 months ago & I've even impressed a few of my friends with my newly found skill of transmission rebuild, since then I had 3 people ask to ask me to rebuild there's all owns a 4l60e. I'm thinking about opening a transmission repair service myself, but I still have so much more to learn about other transmissions as well but your videos put me at a good start. And once again thanks for sharing your knowledge & wisdom to me & the world.
For anyone doing this on the vehicle, when you pull off the 1-2 accumulator housing, there is a checkball above the upper gasket that will fall down. My process for dealing with this was removing the accumulator first, then the valve body while leaving the three bolts that hold the plate stiffener in place with the valve body removed. Next, use one of the bolts through a 10mm deep socket to hold the opposite side of the plate (from the 1-2 accumulator housing) up to the transmission. Remove the accumulator housing and you should be able to see the check ball in place above the plate right beside the large circular opening for the 3-4 accumulator piston. Place a strong fridge magnet on the bottom of the plate below the checkball and then remove the plate. The check ball should stay attached to the magnet through the plate. You can use this method in reverse to reinstall the plate with the check ball on top of it. Your video is SO awesome! Thank you for making this. The TransGO kit instructions should include a link to this!
Before taking off the separator plate by taking off the stiffer plate, put two blocks of wood under the extension, housing and pick up all of the check up the check balls, the magnetic pick up tool, then take the separator plate off and get the check by the accumulator sounds like you’re doing at the hardware
I absolutely love watching your videos. You pack so much information and years of experience into them, they are a real treat for me to watch! Please keep up the awesome work!
I wasn't a fan of Automatic transmissions but after buying my 2006 Pontiac GTO, which is an automatic. I had mine rebuilt to hold extra power that I put on the motor. But I always come here to look at your Videos because they are good. Keep up the good work bro
I thought the camera angles were excellent in this video. Lord knows I'd be lost on a lot of this stuff if it weren't for your videos. Thanks for all you do for us Hiram.
Absolutely Excellent presentation - one of the best and most comprehensive I've seen. Thanks for taking the time and posting. I actually understood it...
You are completely right , with the cheering of the informaron . I STRONGLY APPRECIATE, your time and patience to do what you do and give us the time to do take care to our transmition situation. Good luck. Keep up the good work. Sun comes out to all of us . Blessings
These videos has been the best help for me that’s explained so well. Thank you for your time and sharing such valuable information. I know there’s more tricks but maybe someday you might share those also with us. Thanks again.
Thank you so much for this video I installed on in my wifes 04 envoy and it fixed all her problems with overdrive shifting shudder. It shift crisp and quick now. Just put 200 miles on it today no problems thanks to you.
One of the better videos out there for sure. Best parts? Knowing what the problem would be if certain springs you mentioned break. Learning the importance of the bolt pattern on the install. As far as the longer bolts going through and causing no revers. I always get a piece of foam and stick the bolts in that in the pattern I take them out so I know how they go back in exactly. Low revers piston check ball having broke tabs, flipping the isolator valve for trouble code PA1870. PWM to an on/off. 3-2 down shift spring breakage and having upshift only one time then it takes off in high gear. Just some good info for trouble shooting for sure.
Dude you are the best transmission rebuilder I’ve ever seen I grew up watching my grandpa rebuilding the old turbo 350 and 400 using air hose to make the transmission shift .testing the rebuild but he never explained symptoms and what it causes so basically I’m saying you are a frickin transmission wizard great job ,keep on makin those videos
You rock brother. I spent 4 days studying your videos, I rebuilt my 4l60e on my own thanks to your stuff. 6 or 7 videos on the 4l60 from you, every issue I ran into, you had the answer. Couldn't have done it without you. Now off to try and rebuild a NP246 transfer case... you wouldn't happen to have any videos on transfer cases would you??
wow - ya saved me...I just got done with my 1st 4l60e rebuild - and I forgot to reinstall the dipstick stop...It's still on the bench so no big deal..Thanks for the videos - they helped me a lot during my rebuild...!
Thank you so much for your videos. They really helped me with my 2002 tahoe. I came back to donate but you don't have an option to do so. On the separator plate I have everything stock except took out 3-4 accumulator piston and tapped hole with a 1/4-20 3/4 setscrew with locktight (no need to drill hole) but drilled all the holes except for bottom left 2, I did .073 on those and .093 on rest. My second gear shift is the only one I think is a bit rough. I think I should have done .080 on that one. I also used the Fitzall TCC block off and I'm actually liking how the TC works now (was slipping before) but now shifts early and loads heavy on hills but I think I'll get much better MPG knowing how to use it to my advantage.
Gracias Hiram por compartir tus conocimientos y por darte el tiempo de enseñaros a todos los que deseemos aprender éste bonito oficio!!!!! Dios te bendiga
Hiram-ur videos r very informative and easy for even those with little knowledge of transmissions understand. Thanks for the awesome videos!! Keep them coming!!
we are lucky and we are most happy and grateful ... you are very very very generous, handy and as some of us said already : natural teacher ... thank you :O)
gracias por el video esta bien explicado pocas personas comparten su conosimentos, yo tengo un lema uno puede enseñar a otra persona pero lo que uno sabe o tiene en su mente no selo pueden sacar. una vez mas muchas gracias, DIOS LO BENDIGA.
This is an awesome vid! Dont let the haters and peeky people tell you otherwise Last night, my 07 GMC Sierra with 4L60e picked up not one, but 2 symptoms. I went on the highway and did a 15 min run to a nearby town. Once i returned, and exited the highway i came to a set of lights. Upon leaving the lights, i noticed 1st to 2nd shift felt a little long and the rpms were abit higher than normal... 2nd to 3rd shift feels like its slipping. But i believe its what is called shift flare? The rpms jump up and then back down, as its going into 3rd gear. 4th gear seems to engage as normal... I want to mention that the trans has performed flawlessly up untill this point. And both symptoms happens after getting off the highway. About 2 months ago, i replaced filter and fluid in the trans, as what i thought was preventative maintenance...Maybe i should have left it all alone? I used GM Dexron VI from the dealership. Could the 1st to 2nd issue be a bad accumulator piston? And the 2nd to 3rd issue, possibly the check valve stuck into the plate? Or do these 2 symptoms sound like something else? My fingers are crossed that its not a complete rebuild, cause at this time i really dont have the funds for something like that... just recently purchased my first home, and after down payment, not much left in the bank! Lol Thanks for any info you could provide me I really enjoy your videos, and have actually watched them before my issues started last night! Keep up the good work
Thus video helped me tremendously since the instructions are pretty vague. . I removed the 3-2 seloinoid to change the spring and couldn't get the valve out. I tried everything but still cannot remove it to change the spring. it move forward with the existing spring however I cannot get it out the change to the new spring. Any assistance would be appreciated.
Great tutorial. My sunshell broke in the fall. I'm doing a tear down of the transmission and doing a few upgrades (sonnax sun shell, sonnax accumulator billets performance kit, transgo shift kit, corvette servo and a remco rebuild kit). Price is about 1100 canadian. My question is if I have all those upgrades do I have to have a better quality 2-4 band and a high performance shift kit. I'm wondering if the upgrades will wear out the regular transgo shift kit and remco frictions and band? Thoughts...thank you from Saskatchewan 🇨🇦
Great video just had a quick question that ive been worrying about.drilling the seperator plate for 1-2 shift it says "we prefer .063 for short but smooth (optional FIRM .070) but in your video you went ahead and drilled it to .093.can you elaborate on this please.getting all my ducks in a row to have a flawless install
Hi. I just finished a full 4l60e rebuild for my '98 Sierra pickup. Your videos were a huge help. Thank you. Tranny seems fine other than p1870 code. Watched your other video and did the 1-2 valve switch around with the spring in first to match the shift kit valve and drilled the two holes in my new transgo separator plate. Had good 1-2 shifts but 2-3 was acting funny so I ended up buying a new oem acdelco valve body correct numbered to match my old one. It came assembled and ready to be put in but now that my separator plate is drilled larger should I buy a new plate if I am going to run the valve in it's stock configuration? Is the increased hole size going to make a difference? My old valve looks like yours in the video with the two cups that fit over the small spring. The new valve has a larger spring that fits over two posts one on each of the two valve pieces. I figured I would leave it stock and run it as is but I'm not sure if the increased size of the two holes is going to cause a problem for the stock valve body? Thanks, Alex.
He kind of does explain the difference the correction kit corrects problems in the existing transmission and high performance is 4 High Performance Racing,,, Towing.. things that will be hard on the transmission ....I hope this helps
I have a late 4l60e with the ISS sensor. I have a shift kit for it and was wondering if it was a bad idea to pull the pump to put the boost valve and spring in and put it back in. The trans works fine shifts through all the gears perfect. It is more of a preventative thing.
You're in Deer Park right? I wish I could get my 97 accord to you. 214k miles and ready for trans overhaul. I know I would have a good rebuild if you did it. Hoping you will start taking ship-ins soon. Keep us advised on that. Steve (near OKC)
You drilled the 1-2 and the 2-3 to .093"? Also I think you missed the hole by the Z bolt of the pressure manifold. One is always bigger than .093", but the other one it a few thou smaller.
I just wanted to drop you a quick note and tell you how much I appreciate all of your hard work on your transmission videos. I know how much time and effort it takes to make your videos. I invite you to check out my channel if you have time for all your small engine repair needs. From one RU-vid creator to another have a great day sir. keep the videos coming
You can make a 4l60e shift hard like that shift kit get a corvette servo block it inside and also turn up the pressure selonoid and block the accumulator and there thats the famous shift kit
I love your videos Hiram, you have taught me a lot. I've noticed in the past you always used your 12 volt to start the bolts on the valve body and then torqued them down to 9 foot lbs. What setting did you have your 12 volt on to finish the valve body in this video and can I use this method with my 9.6 volt makita? Thanks sgain Sir.
love the videos man they are a lot of help. rebuild kits would u recommend for a 94 chevy 1500 4l60e, looking for something that will have all i need but not break the bank , if u have any suggestions i would really appreciate it.
If yours is stuck on, then your trans likely overheated and you're probably looking at a complete rebuild. I have a high-mileage unit and had minimal sticking. Use a razor blade or utility knife blade to carefully remove the stuck gasket.
ohh ok i was just wondering,actually iam rebuild my own 4l60e because i have been truggling with 5 diffrent builders and the built only last abt 3 months, so i got a good working transmission and iam starting my build
I have a 4l60e in my 4WD Avalanche with about 115K on a rebuild. It really works well - I flush it every 30-40K - but I'm starting to notice a slight and occasional 2-3 flare. Was thinking about pulling the VB and installing that Transgo kit, I figure even if it doesn't help it can't hurt...right? It's an '06 so I presume it's one of those that I can't change the boost valve w/out pulling the trans so it's staying put. But is there any reason I wouldn't want to install that kit? What other extra parts might I want to throw in while I have the VB out? If it's one of those gasket-less setups can I throw gaskets in anyway? Your videos do rock!
Go Hiram go! this is better than any tv show for sure well istill like my little pony its the only good cartoon with enough play on tv to be noticed its really good, but this still is just awesome! Well and I also like rick and morty, jo jo's bizarre adventures, and ben 10 but for serious non cartoon this is the best!
Hiram; is this the same procedure for a 4L65E? I would think there aint much difference. I predict you will be bless 100 fold for sharing! Keep it up. You are the Jay Leno of transmissions! P.S. Are you located in So Cal and if not can you recommend anyone in So Cal for a shift kit install or rebuild. Thanks again!
