My name is Brad Wilde I have been rebuilding automatic transmissions for over 30 years. I was factory trained at college and ASE certified in transmissions.
i give your presentation 10 out 10. for cleanliness of workshop, of work area, the riight toolsand really clear explanation of what you're doing, This work is not a walk in the park but you have made it easy to understand and appreciate what it is all about. Thank you so much.
I was watching another channel and when he started putting a new 3-4 piston in a filthy transmission full of burnt fluid and grit I stopped and found yours. This is the kind of instructional video I like. Thorough and done right. I'm not quite ready to attempt a rebuild by myself yet But I will definitely watch this build series again.
Thanks, Brad, for a very informative set of vids. I'll never get inside an automatic transmission myself, but it's very helpful to watch you do it. I especially liked your explanations of assembly errors that can cause problems down the road. The more detail, the better.
Seen several videos of transmissions dismantled and reassembled, but you have earned my full respect, as you done the whole job proper way, especially lightly lubricate all the seals and bearing and using hand tools and advising never to use power tools on assembling most critical bolts, finishing with tightening the bolts to its recommended torque settings, really impressed by your work standard ,keep it up, all the very best....thanks for the video from start to finish.
Thank you for let us watch a professional rebuilding a transmission with so much knowledge and the way you detail and inform the procedures to performed this job. Keep it up Brad.
Congratulation Mr. Brad for having a very good skill like this it is potential and helpful indeed i wish to know more on how to rebuild the automatic transmission because in Africa especially in the united republic of Tanzania a person like you are very few. once more congratulation.
Hi Brad, just wanted to Say thank you very much for your advice and your Videos, after a couple of months of slowly rebuilding my 4L60E (4WD) for my 99 Suburban I am happy to report that it works like a charm, no issues. I greatly appreciate all your knowledge transfer keep the videos coming, Thanks.
Hi Brad, watch both vides of rebuilt of 4L60E , its great help , quality, professional work , it was a major overhaul , also like your workshop , very neat n tidy place, great experience learn, imran
Great video series, just finished watching all three, very detailed and informative thanks again!!! i supposed the geniuses with the down votes do not know what a transmission is.
Man you are a perfectionist and know exactly what your doing ! I want to congratulate you sir on your skil and know how ! Would like to see you build more automatic transmission, maybe an older Toyota Corolla or something... Thank you for the video ! If you work for a company they're sure lucky to have you . Job well done !!!
Outstanding! Probably the most conscientious (or one of the most) rebuilds I have seen. And I have been watching them all. Getting ready to rebuild my 95 4L60e, which, unfortunately was a one-off year. Thank you for sharing your expertise.
By the way. My 3T40 transmission failed in reverse. After disassembly it I found two out of four friccion plates worn to the bare metal in the L&R clutch pack. And I also have the L&R piston deteriorated from its outher lips, "a chunk missing and a vertical cut". When you apply air it escapes from the damaged seal. I think this is the major cause as you said:" Old piston seals need to be replaced". Wise words man.
Excellent series. I've built hundreds of these. I'm always on the lookout for better ways to do things. I picked up on a couple of things to make life easier, like the drill bit trick. Thank you
Thank you so much, I have been trying to figure out how to get that 2-4 band in for 2 days now and no one has explained it as well as you did, I hope this helped me enough to get it!!!
I will use 2 old but resurfaced 0.092" steels to adjust 0.032" to 0.62" the clutch clearance. The cushion cone shaped steel is gone be installed pointing upwards I don´t know why but I´ve seen this practice in a pair of videos. Saludos amigo Brad.
Brad I take another low/reverse piston and flip it over on top of the one I'm installing in the case and use it as a driver and hit that one in with a dead blow. Works every time.
Brad! thank you for sharing this great video. One of the best seen on youtube. I am wondering if there is a way you can give as links or PDF doc. to the measurement and specification for various clutches, endplays, and etc. This will really help newbies like me to disassemble and assemble auto. trans. Thank you again
sir, we just tore a 95 4l60 down.. the only thing we found were REALLY cooked low/reverse clutches,, the guy we bought it from said it had no reverse, but didnt mention no low gear.. what would cause just the low/reverse clutches to burn,., I dont want to put new steels and clutches in and it burn again,, there was alot of clutch material in the 3rd acuumulator bore.. thanks
What is the item laying on your shop rag? I hate it when anything is left over when I have things put back together... ;) EXCELLENT tutorial, thank-you!!!
I plan on replacing all of the electronic parts in my valve body this week. My 4l60e has 317k miles. It's never been torn apart. Can you use just new clean transmission fluid to coat the new solenoid o-rings before inserting them in the valve body. I noticed you used assembly gel to coat the o-rings.
Great video. Thanks! I. Want to make sure I understand where the full mark on the dipstick reads while it’s installed so I don’t make a deadly mistake. The full mark / second hole is about a tad more than 1/2” lower than the pan gasket. Is that correct?
nice job but why would you put the "chatter spring" back in a stock 4x4 instead of using the approved case saver upgrade part it is a better part and is very cheap it will indeed help the life of the 4x4 unit
This video far surpasses anything that I've seen so far. Do you place the transmission on a dyno and check the pressures, shift points, look for leaks and all the electrical before you reinstall the transmission? It's a lot of work to put it back in the vehicle and then be disappointed.
No I don't. I cant afford a dyno for home use. In fact the place I work for doesn't have one either. I'm lucky I can't remember the last time I had to pull a transmission back out because it didn't work.
I have so many questions. I have overhauled 10 to 15 of theses so far, and have been successful more or less. I have books and have watched other videos as well but there are still things I get hung up on. I would really enjoy building one with a professional builder just once so I could ask questions. I am a Master L1 certified technician and have been repairing cars for a little over 30 years. If you don’t mind me asking where did you go to school and how much did your schooling help when you first started building? I’m not afraid to pay for knowledge and definitely don’t mind buying tools.
the c clip has a slight bevel at the opening. put it so the pointed end is up, this will give the next person something to grab on to when getting the clip out.
@@bradstransmission3846 you are the master! I could not figure out why. Is that why it’s painted? What’s the significance of the yellow paint? I also saw 4 dabs of white paint on top of my planetary. Would you know?
H Brad, I just took apart my 4L60E. I have 1999 Suburban 4x4, but now I can't decide if I should rebuild it or not. there were broken pieces of metal everywhere. The Outer Ring gear cracked, a big piece of the rear planetary gear set broke off. The broken pieces even got between the low reverse piston and the piston bore and caused deep scratches on both of them. the big question is should I rebuild this Transmission or just get a used one and rebuild that one? can I just sand out the imperfections? I would appreciate any feedback, I don’t want to waste all my work and order a master kit, plus parts for a case that might be a total loss. Thank you.?
Great video. I got a quick question I hope you can answer. IF you have to take the pump back off (after you torqued it down) can you reuse to pump to case paper gasket?
Great video Brad! Two questions though... the anti-clunk spring in the low reverse - I thought you wanted the snap ring to be installed over the flat part of the spring to hold it in place and second, when you install the pump and use a mallet to seat it down don't you worry that you will knock the plastic washer off from underneath and then have an issue with those two tabs not aligning? I know you use trans gel to hold it but I always use the pump bolts to gently move it down so I don't have to worry about the plastic washer coming loose. I don't have anywhere near your experience and expertise in rebuilding so your opinion would be greatly appreciated!
You don't need to have the snap ring over the flat of the anti clunk spring. But its ok if it is, just not over the wide part of the spring. No I never worry about the thrust washer falling off, never has happened in over thirty years of building. Thanks!!
I've watched all 3 videos on the 4L60E rebuild. Good videos. I've lost 3rd and overdrive. I still have 1st and 2nd and reverse. They are still strong. What has failed on my transmission?
I rebuilt my 4L60E, it now shifts great. Unfortunately, I have the same symptom as before, transmission or gear fluid slowly dripping from the extension housing/transfer case meeting point. I read somewhere that this was supposedly a 'dry' area. Any ideas? Could it be the transfer case fluid?
Excellent video series! I really enjoyed watching it, and your experience really shows Im about to tackle the 4l60e in my 2007 gmc sierra 2wd What overhaul kits do you recommend? Last weekend after exiting the highway, i noticed that upon leaving the first set of lights at an intersection, my 1st to 2nd shift seems a bit delayed... Also 2nd to 3rd does what i believe is called shift flair? Weird thing is, after the truck sits over night, the first little bit of driving seems to be fairly normal... But after that, these 2 problems get worse. But only under heavy throttle. Ive been driving this week with a really light pedal, and its shifting fine... Not sure if maybe the forward pistons are leaking or possibly the accumulator pistons are leaking? Regardless, id like to order a decent kit and pull the trans apart. I will be going over your vids again once i get to this point! Thanks
Just look around on the internet. Remember get a good quality kit with pistons. that does not mean get the most expensive kit. I use Transtar Kits. remember cheep kit means cheep parts.
Brad's trana thank you for the video .i have a transmission zf 5hp 19 .the trans do not engage any gear ,fluid and filter was change ,help me please .thank you.
I use ATF because it's easier and cheaper than lube. I use precision kits at work and home they come with Raybestos frictions and steels. There are a lot of friction manufactures out there, just do your homework.
great video, I intend to rebuild a 6l8oe soon, just for interest sake how much in us dollars would you pay for a 6l80e with moderate miles on it to rebuild. thanks mark in ( Australia ).
Thank you again Brad! I just replaced my broken sunshell. I put my trans together and noticed my input shaft play has almost no play at all. I can turn the shaft by hand but I have almost no play at all. Is this an issue or can I install the transmission?
Just did my 94 Astro. I seem to have a lot of side to side movement in my 4L60E output shaft. Is this normal. In and out end play is ok. It just seems sloppy to me....
You should have very little side to side movement. If so you need to replace some bushings and see if there is any worn out parts. replace as necessary.
I just finished building my 4l60e for my 2004 GMC Yukon. Installed it, and it will not shift out of 1st gear. I checked all the new solenoids with the scanner. They all are working properly. The scanner shows the computer is commanding the shifts right. I removed the valve body. Went thru everything again. Checked the 1-2 and 3-4 accumulator pistons they we're good. I checked the seals and springs on the service also. It still will not shift out of 1st. Even if you manually shift it. I'm all out of ideas at this point. I need someone with more experience to suggest what might be wrong.
Ok the only thing that comes to mind is the valve body. A lot of scanners have a shift transmission function. try that. see if you can hear the solenoids click on and off. Does your speedo work? Is it starting out in first?
It is quite evident you know what you're doing - however, I am a bit perplexed as to why you would reuse the plastic accumulator pistons which are prone to cracking and did not install the updated aluminum pistons which correct that problem
Brad ~ I pulled up the driveway with my 98' Savana 4L60E & without warning lost all forward gears. I have reverse & it is solid. Do you what has happened? No metal in the pan. Everything clean. Checked fuses, linkage, lines, no a single drop anywhere. I am stranded at a friends house. I see no problems at all. Solenoids?
Hi Brad wonder which transmission parts should i get for full Rebuilt transmission ? i have 1998 Chevrolet pick up truck engine 5.0 4x4 1500 1/2 ton Cheyenne. and i need to get batter gas milage
Sorry I haven't gotten back to you until now. I don't get an alert with every comment. with that transmission it wont matter what parts you replace for gas mileage. It's all in the way you drive. Sorry>
Hello Brad, I just put up a 4l60E gear box on my blalzler 4.3l 2000 and when I tried to turm the engin on it would not start. With the old grear box the truck would start with one trun of the key. I do not have an idea what really happened. Can you advise on the matter.
Hello Brad, I am packing a Direct Drum of a 3T40, but used steels are thicker than new ones, let´s say 0.092" vs 0.077", when we must use ones or the others ? Thanks in advance .
Martin, The 3T40 transmission has 0.090 thick steels in the direct drum (the one the band rides on) The forward drum has 0.076 steels and two waved steels. (drum with the shaft) the Forward and direct drum clutch endplay is 0.040 to 0.060 Hope that helps.
I´m putting together a 3T40, with a ATSG service manual for Parts Number P.N. reference. Now I am installing new lube bushings, (bushings with internal oil chanels), and my location choices are: 1st: one goes into the case transmission, (P.N. 112, next to the right axle oil seal, where it rests the non pinions side of differential carrier), 2nd: gear final drive internal( P.N. 673, where it splines over the differential carrier pinions ), and 3rd into gear,reaction internal (P.N. 668) (the one that holds sprage assembly). By comparison of height, Internal diameter, outher diameter, bushing dimensions, with the used bushings, it make me sense to locate the new replacement bushings into these 3 location choices. Any recomendations dear Brad?. It worries me, to misplace one bushing with internal oil channels and cause a oil pressure lose. As always, I will appreciate your invaluable experience, Thanks a lot.
If I remember right you can't put the bushings in the wrong place they won't fit. It has been 15 to 20 years sense I've built one though so I could be wrong.
i give your presentation 10 out 10. for cleanliness of workshop, of work area, the riight toolsand really clear explanation of what you're doing,

There should be a crosshatch pattern on the stick. When the transmission is at operating temperature the fluid should be in that area.

Just did my 94 Astro. I seem to have a lot of side to side movement in my 4L60E output shaft. Is this normal. In and out end play is ok. It just seems sloppy to me....
You should have very little side to side movement. If so you need to replace some bushings and see if there is any worn out parts. replace as necessary.
+Brad's Transmission thanks man hopefully it will be ready soon
I just finished building my 4l60e for my 2004 GMC Yukon. Installed it, and it will not shift out of 1st gear. I checked all the new solenoids with the scanner. They all are working properly. The scanner shows the computer is commanding the shifts right. I removed the valve body. Went thru everything again. Checked the 1-2 and 3-4 accumulator pistons they we're good. I checked the seals and springs on the service also. It still will not shift out of 1st. Even if you manually shift it. I'm all out of ideas at this point. I need someone with more experience to suggest what might be wrong.
Ok the only thing that comes to mind is the valve body. A lot of scanners have a shift transmission function. try that. see if you can hear the solenoids click on and off. Does your speedo work? Is it starting out in first?
It is quite evident you know what you're doing - however, I am a bit perplexed as to why you would reuse the plastic accumulator pistons which are prone to cracking and did not install the updated aluminum pistons which correct that problem
Yes they do break, but they won't ware out like aluminum does. So you can use either one. It is up to the builder. I'm good either way.
Where are u located at an what do u charge to rebuild a 4l60e
Brad ~ I pulled up the driveway with my 98' Savana 4L60E & without warning lost all forward gears. I have reverse & it is solid. Do you what has happened? No metal in the pan. Everything clean. Checked fuses, linkage, lines, no a single drop anywhere. I am stranded at a friends house. I see no problems at all. Solenoids?
no manual low? Forward Sprag?
Maybe band?
Great job! That was like 2 hours plus hot tank time. What does that cost for that job?
It took me 3 weeks to shoot this video. An overhaul runs about $1200 just for the overhaul. No instillation.
OK.nice
Hi Brad wonder which transmission parts should i get for full Rebuilt transmission ? i have 1998 Chevrolet pick up truck engine 5.0 4x4 1500 1/2 ton Cheyenne. and i need to get batter gas milage
Sorry I haven't gotten back to you until now. I don't get an alert with every comment. with that transmission it wont matter what parts you replace for gas mileage. It's all in the way you drive. Sorry>
Hey good video ., i have a 2015 yukon that is making all kine of weird shifting , are u perhaps in the NYC area ??
Sorry no. Salt Lake City Utah.
La mía dejo de funcionar la reversa ,q me recomiendan repararla completamente o solo reversa
Sorry ?
Have you ever seen a 4l60e go bad and lock up an stay locked up so the motor won't turn
Sorry no I haven't.
Hello Brad, I just put up a 4l60E gear box on my blalzler 4.3l 2000 and when I tried to turm the engin on it would not start. With the old grear box the truck would start with one trun of the key. I do not have an idea what really happened. Can you advise on the matter.
Maybe a bad PRNDL switch?
Hello Brad, Is that the neutral security switch. It cranks on P, but does nothing on N
Yes it sounds like the natural safety switch is bad. need to replace it.
I have problem I and II interlace and the third and fourth does not respond؟
Not sure what your talking about. are you sure it's first and second? Not first and third? exactly what do you mean in 1 & 2 interlace?
Hello Brad, I am packing a Direct Drum of a 3T40, but used steels are thicker than new ones, let´s say 0.092" vs 0.077", when we must use ones or the others ? Thanks in advance .
Martin, The 3T40 transmission has 0.090 thick steels in the direct drum (the one the band rides on) The forward drum has 0.076 steels and two waved steels. (drum with the shaft) the Forward and direct drum clutch endplay is 0.040 to 0.060 Hope that helps.
Thanks to share your invaluable experience.
I´m putting together a 3T40, with a ATSG service manual for Parts Number P.N. reference. Now I am installing new lube bushings, (bushings with internal oil chanels), and my location choices are: 1st: one goes into the case transmission, (P.N. 112, next to the right axle oil seal, where it rests the non pinions side of differential carrier), 2nd: gear final drive internal( P.N. 673, where it splines over the differential carrier pinions ), and 3rd into gear,reaction internal (P.N. 668) (the one that holds sprage assembly). By comparison of height, Internal diameter, outher diameter, bushing dimensions, with the used bushings, it make me sense to locate the new replacement bushings into these 3 location choices. Any recomendations dear Brad?. It worries me, to misplace one bushing with internal oil channels and cause a oil pressure lose. As always, I will appreciate your invaluable experience, Thanks a lot.
If I remember right you can't put the bushings in the wrong place they won't fit. It has been 15 to 20 years sense I've built one though so I could be wrong.
