Hello hope it's not inappropriate to message you this way but I'd like to ask a question. You appear to be very wise and educated on the tranny issues. 93 Chevy 5.7 no second gear . Do you have any ideas or comments on my problem!! Thank you in advanced!!
@@bryanmartinez6600 yes sir everything seems fine just will not go into 2nd gear. Although I can pull it down and reverse out of park I can feel it take gear I feel it go to neutral I feel it going Overdrive I Feel It Go in Drive I feel it Go in first but when I put the lever in second gear about two to three maybe four seconds when it should take gear it kills the engine feels like on a straight shift you just dump the clutch
@@joshuawilson9086 I was thinking it would have just been your 2-4 band but these 4L60E fail randomly. I plan to tear apart a cheap rebuilt I bought but has no gears at all it only drags forward even in reverse, I wonder what I'll find.
Just a couple of comments to add as we go into 2020. First, it is important to leak-check the orifaced cup plug in the front of the input housing & shaft assembly. Re-stake or replace after cleaning and fails to seal for the 3rd - 4th apply piston. Secondly, improved “Blue” rubber compounds that withstands the thousands of heat cycles and wear from movement sold in sets of 3 of steel molded pistons. These will last way longer, unless you need repeat work every 8 years! I’ve known many techs who skip steps and don’t even know the Oring that goes onto the internal nose of the input forward housing shaft assembly before the 3rd - 4th clutch piston is installed. ASE Master Tech / 1978 / Retired Other, nice series of sectioned lessons.
For those building a 82 - 93, TH700r4 - 4L60, using the “Blue” rubber type molded steel pistons, the spring retainer shown at 10:21 is required. It is ACDelco p/n 24206085. It is narrow and has a steel end plates and works with the same clip. This “Blue” rubber compound is 4-5 times more resistant to heat, retains its shape way better and allows for use of the 0.50” boost valve that increases line pressure and can deform the aluminum pistons. Checking for bent or deformed aluminum pistons is in the GM service manual. Low & reverse is the same but by design is heavier to start with. ASE Master Tech since 1978
Levi, That a cool name! It is normal to add Solvent or mineral spirits 2 part to 1 part ATF. Using a hypo or straw with finger on end, fill the ball cap almost full. Take a lunch then check under it. Should be dry. Remember, 2 check balls in capsules, one at center rear and other over servo’s. High wear on high mileage cases and rarely checked. GM’s service manual says to use a #4 easy-out, I use a 3/8 fine tap. (Test for fit on size, but use fine) screw in until it grabs & turns. Place a flat plate on VB surface, grab with vise grips, turn, push down on handles if you place a flat fulcrum for pivot 1” back and it should pop out. They say to measure top for depth but it bottoms out with 3/8” drift. Cheap insurance for $6. Best to change, up to you but stay safe and wear a glove to watch fingers. Hope this helps! (Tip) hit video gear in upper right when at regular screen. Change speed to something faster. See something, slow down to normal the re-play. The easy-out trick is in the video I think. He is an “STG” GM instructor. Have a good one! ASE Master Retired.
Sir you have given me the confidence to try and rebuild my trans in my 2002 bravada I know something about repair, but never tried to rebuild a trans before, your instructions are very easy to understand and very clear, I have all the tools to do it with and I will be putting my computer in the garage and follow you step by step, it's amazing, youtube and you. I just want to thank you for taking your time out to help many of us that has limited options. THANK YOU SO MUCH.
THANK YOU!!! I am stuck in Mississippi rebuilding my transmission trying to get back to my kids in Houston... this video was a great deal of help.. I can't thank you enough!! This is my 1st UA-cam subscription and I have been using UA-cam for years! You are a great teacher!.
thanks again. I will be rebuilding my 4l60e soon. its a 93 in a 2wd chevy truck with 280,000 miles. its starting to slip. this series of videos is very helpful.
Wow! It's amazing how long some of them last. Even at 280,00 miles, YOU can make it like new again. Thank you for the comment. It inspired me today while writing narration for lesson 6. By the way, since you mentioned that the videos are helpful, do you have any suggestions to make them better? I still have lessons 7 through 10 to write and film, so please criticize the ones I've done so far....and good luck with your 4L60E. Jimmy Check out www.transmissionbench.com.
the videos are pretty good as is, can't say i would change anything. I've been a mechanic for 30 years but never attempted a trans overhaul. thanks again and looking forward to the rest
Transmission Bench Change Anything? No Sir, These videos are the difference between success and failure. I had a forward sprag that felt smooth as silk, and I was going to drop it back in. You said "take it apart and inspect it". I felt obligated to listen to you since you've done such a tremendous job. Sure enough the brass thrust was so thin you could see daylight through it. So, Thank You for these videos. Joe in Tx
Greatness, saved my butt At 70+ hard to remember stuff you read and did in 80s, then do it 2016. thank you, SS gets in , will get on board 5 week months are killers
Since this video was made 9 years ago, there are a number of improvements to the 3/4 drum. Rather than use the type of pistons that failed, use a SEAL-AFTERMARKET Hyper-Blu piston set. When you take apart the input sprag assembly, if you find the gold washer set as pictured, discard the sprag and washer assembly and replace with an improved Borg Warner set. Also, this video made no mention of inspecting the back or the housing that has the 6 tangs. It should be smooth. If it has grooves, replace it. When you do the air check to the drum (@30:32), first pour transmission fluid into the area where the spacer and bearing goes. Then apply air. Look for air bubbles. Check the other 2 apply holes and look for air bubbles. No bubbles, good to go, .... got bubbles, then tear down the drum, push out the shaft and re-seal the input shaft to the drum. By the way, nor was it mentioned about checking the drum for wear on the splines where the clutches ride. Look at 31:30. Below the lower teflon seal. Those splines should all be full with no wear. You can see in the picture where the splines are scuffed, but not worn. if the splines are worn, time for a new drum. Odds are you will not find a new drum any longer and will need to find a good used drum. But, yes, there are still new drums available, I keep 4 or 5 on my shelf. And speaking of the 4 teflon seals, (also 2 on the pump stator) REPLACE them.
took me awhile to find this comment! The gum was in part 1 lesson 1 and then disappeared only to return on this vid, part 2, lesson 5. I'm not trying to do a rebuild - only just want to learn and listen to the gum chewing!! It drives some people crazy I guess - I thought it was a lozenge at first for dry mouth. Now I understand it's just all about street cred and "verga" as the Mexicans say....
OMG don't try to use regular snap ring pliers. It's nearly impossible. Use lock ring pliers, they are made for these type of lock rings and make it so much easier.
Your Exactly right ! Many HOURS ! Added time. Now after wasted time I took a chance and got out my imitation Dremel tool with a Cut-off wheel, I cut a tiny grove right past the end.... it worked first try ! Wish I thought of that weeks ago. Of course it only works for reassembly! Be careful u don't cut grove to deep
I just wanted to add that only 4l60 takes .060 inches of clearence as a minimum between the 3-4 backing plate and first clutch plate. The specification is .060-.094 as stated in the video. However, the 4l60e takes .035" to .083" of clearance. That info is per service manuals. I got on mine 0.45" of clearance for a 2005 Trailblazer. I just wanted to put this here if someone is not getting the .060 despite using different size pressure plates; saving you the hassle 😅 I experienced. Always check your respective GM unit service manual
I was wondering this because I replaced my 3-4 pack with 6 friction plates and 5 steels at .106” and the clearance was only .035” and it was all stock frictions and steels but the video somehow gets .60” clearance event though we supposedly used the same parts. I went ahead and changed one of the steels to a .076”, which gives me an addtional .030” or a total of .065”. I don’t mind being on the higher side.
@brittoncorbin7144 you are good there with .035 i would believe but take that with a grain of salt; i'm not trans rebuilder. Just a general mechanic. However, That's what the Trailblazer unit repair manual states and i have a GM unit repair for 98 and calls the same. I tested different plates and the best i could based on this video was .055. I left it a .045 though.
@@koffeegreaseaddicts thanks. Yes it’s a little confusing because this guy is the guru of tranny rebuilds and he said “it’s critical that the end play be between .060 and .085”. I take him for his word and you know he knows the GM specs so I reading between the lines that the end play needs to be a little higher than the factory specs, otherwise he would have just repeated the factory spec of .035 to .086. But then you research and watch the other videos and everyone aims for .035” which is exactly what I arrived at the first time!! The folks wanting the tight clearance claim it makes for firm shifts but the folks wanting the higher clearance talk about increased fluid flow, lubrication and reduction in temperatures. AHH. Very confusing.
hi i was wondering if someone could help i rebuilt my first tranny a 4l60e and put it in every thing worked just not 3 or 4th gear it would just rev real high like it was slipping but after taking it apart again i noticed my gap was at .105 and its supposed to be between .060 and .085 would this cause the revving problem it seem like it has to be it thanks
I did use the .060 to .085 and .one is working fine but it looks like they recommend .025 to .040 so I don't know I hope it last my kit car with the alto power pack with 9 frictions and some different sized steels and another I believe top plate but I don't recall
I've seen plenty of transmission performance companies that like to install 9 clutches in a pack and can go as far up to 15 stacked! Do they simply use thinner clutch frictions and steels to achieve this, or do the bearings and washers have to be modified as well?
Hey I have a 04 gmc sierra with this trans and a new process 246 behind it. Do you know if transmission fluid is supposed to come out around the output shaft on the transmission in between the transfer case. I have my transfer case out and just rebuilt it and noticed with the engine running fluid squirts out around the output shaft on the transmission. is this normal our do I have a seal leaking. Thanks in advanced for any advice.
Hi Tyler. This is normal. The adapter housing will have fluid from the transmission in it. If you look, you'll notice that the splined input shaft of the transfer case has a seal around it to keep the two areas separate. Jimmy
I've got my transmission tore apart and was not happy with what I saw. I paid 1300.00 dollars 5 years ago to have it rebuilt and all the clips on harness broke, harness shell broke in half valve body bolts loose . My main problem was 2nd and 4th slipping found drum burnt and band burnt , drum is ruined luckily I got one out of my practice transmission and harness is pinned the same just have to cut pwm solenoid out . Thanks again will let you know how it turns out .
Hi I got a ford freestar and the problem is : first of all , the van is driving and shifting perfectly but after 15 ,minutes every gear begin to slip. What do u think that is the issue jimmy? Thanks for your time and in addition, yours videos are the best
+Jonathan Nourian Hi Jonathan. The booster valve and sleeve in the valve body of these transmissions wear badly too. After the fluid thins out from heat, the pressure drops. Jimmy
Hi. Unfortunately I do not carry parts for those transmissions. You might try calling Whatever It Takes Transmission Parts. Their number is 1-800-940-0197. Jimmy
What if the input housing has a few scuff marks around the top rounded edge of the housing (About 1/2 inch below the top where the splines are on the drum). The scuff looks like it is from where the reverse input drum sits on top of the input housing. Could the scuffs on the input housing be caused from that? Or maybe from 3-4 packs being burnt out, hence why my truck only had 1st, 2nd and reverse? Once my truck shifted to 3rd it was like I had pushed in the clutch but on a automatic transmission.
question on sprag thrust washer installation at 14:14 if I put the thrust washer as per your instruction, and install the 3-4 clutch pack and snap ring and I can grab the sun gear and it seems very loose, is this condition normal? If I flip the thrust washer and put it in the looseness of the sprag clutch assembly is much tighter but not and little loose.
Hi Jackson. It is VERY loose.This is normal. It feels loose because the assembly is actually supported by the sun gear and output shaft after the input drum is installed into the transmission.
I have a 1996 impala SS, with that being said, the three pistons in the input housing are cast aluminum. Will the 1997 or newer steel bonded pistons work in the older style 4l60E's?
about the 3-4 clutch clearance, many people say .020 for the 3 4 to work best , is your measure of .060 to .085 a revised clearance . Maybe comment on what works best for high performance..... Please , nice videos , John
Great video this is exactly what I needed I appreciate you taking the time of going step by step on it. One question please is my 1996 chevy 2 wd has no reverse or forward what should I be looking for when I get in the de assembly please and thank you
As I view this video at around 16.20 or so, I see that the sun gear snaps in and out of the sprag race - with the need to use a hammer. On my 1997 unit, this sun gear does not need to be installed or removed from the race with a hammer, it is easily removed by hand... Is that normal? Is that a sign of excessive wear? or is this normal?
Please help Can you tell me why my truck will start off good will go from first second and third will not go in to fourth .. once it has went through first second third it will not downshift and if I downshift manual it only goes back to second if I shut off the it will go back to first and do it all over again
you never mentioned how the 1993 version assembly goes. its slightly different and i cannot continue and have to look else where to finish that portion for the 3-4 clutch pack assembly and im having a hard time finding info on my year 4l60e
Great video.In My 4L60e,in my 2000 Chevy s10,I was driving and noticed it slipping a little.All of the sudden it quit pulling.Like it went to neutral.Next day it worked until it got warm,then nothing.What you think.
Wish your videos would have been around when I rebuilt my 4L60E out of my 93 truck. But I haven't had any issues. I just ended up replacing the input drum with a hardened 300mm shaft that hopefully won't sheer at 600hp. And I replaced and the clutches and frictions. I've learned quite a bit from your videos if I ever end up having to rebuild it again. Is it ok to use a 13 vane pump on a 10 vane transmission? I'm just wondering because I put one on mine. Haven't had any problems just wondering. Also using a hardened welded sunshell and 5 pinion planetaries out of a 4l65E.
Hello I'd like to ask for your expert opinion on my 93 4x4 I have no 2nd gear everything else fine . What do you think my issue is? Thank u in advanced
I disassembled my drum assembly and was able to get the overrun piston out how do you get the bottom section out so you can access the 3/4 piston I don't want to damage anything and I talked to her in a little bit I just don't want to put too much pressure
Thanks so much for the help . You took the scare out of it for me. Do you know if a 94 transmission case is the same as 97 case, both without removable bell housings and if the electronics are the same .thanks again.
I'm setting here watching valve body lesson at 8 o'clock in the morning when you replied lol. Just to let you know your my new best friend lol . I bought a core transmission for learning purposes . Thanks for replying so quick . Look forward to learning more from you .
I've been following your video I am going to try and get this fordf700 and when you put it in reverse it kicks out of gear in a hard pull what do I need to do
Question I was taught how to do Ford Transmissions about 40 years ago I haven't done one sense my question is my instructor told us to always rough up the steel plates with fine grit sandpaper and then clean them I don't see anybody doing that anymore is it not necessary please advise
Where do I get the correct overhaul kit? Mines a (94 4L60E one piece case) and I'm beginning to lose 4th gear. It's attached to a chevy 350 in my 94 chevy c1500 Cheyenne. I've got a pretty big parts list cause this transmission has never been touched except to replace the engine. I'm expecting everything to be worn out that you show could be.
So my 4l60e is a 1 piece from 94 the 3-4 piston spring set is different than what you show. Yours is 1 piece mine is 2 from the 94 version so im assuming i have to use old one??
I am in the middle of my 4l60e rebuild. I order a power pack clutch set for the 3-4 has a total of 9 friction plates and 10 steel plates I can't not find a diagram neither could of figured out how to stack them up. I ended up placing a friction plate at first and a steel plate and so for a total of 8 friction plates and 7 steel plates my gap between the snap ring was over the 85 thousands of an inch. Any suggestions..? I remember at the end of this video you talk about the different ways of stacks but I went for the last one you said that in the middle of the stack to steel plates would be one after the other . You think that would work for me.
Hi Gilberto. It is extremely important to get the endplay .085" or less. If you cannot find a combination of frictions and steels to arrive at this amount, there are 3 selective end plates available. The thicknesses are: ,227", .192", and .157". You already have one of them. Measure and find out which one you have and order the other two from a GM dealer or Transmission Bench at 706-414-9945. I hope this helps. Jimmy
It would of been cool to air test that clutch pack b4 dis assembly and show us that there was a major leak n the pack then diagnos the bad piston or broken seal or what ever else could cause that to happen
I have a 2007 Tahoe LTZ and lost 2nd and 4th gear.. With shifter in 3rd.. I have to rev out 1st and blip of the gas to shift into 3rd bypassing 2nd.. Still no 4th gear but can Cruz all day on freeway doing 85 just high rpms because no 4th.. Been driving Tahoe all day every day like this for 6 months.. Any thoughts would be greatly appreciated... Thx
Question on the forward sprag assembly. You show in the video to hit it out with a 1 inch socket, mine cones out by hand, does this mean its bad?! Thanks!
the steel plates squeeze the friction plates as the steel plates spline to the sun case (or something like that). hahaha. Go to SouthPaw Autoworks for the BEST transmission "explain" vids of how they actually work - he even uses animation.

Checking for bent or deformed aluminum pistons is in the GM service manual. Low & reverse is the same but by design is heavier to start with.

How do you leak check the cup plug?
Levi, That a cool name! It is normal to add Solvent or mineral spirits 2 part to 1 part ATF. Using a hypo or straw with finger on end, fill the ball cap almost full. Take a lunch then check under it. Should be dry. Remember, 2 check balls in capsules, one at center rear and other over servo’s. High wear on high mileage cases and rarely checked. GM’s service manual says to use a #4 easy-out, I use a 3/8 fine tap. (Test for fit on size, but use fine) screw in until it grabs & turns. Place a flat plate on VB surface, grab with vise grips, turn, push down on handles if you place a flat fulcrum for pivot 1” back and it should pop out. They say to measure top for depth but it bottoms out with 3/8” drift. Cheap insurance for $6. Best to change, up to you but stay safe and wear a glove to watch fingers. Hope this helps!
(Tip) hit video gear in upper right when at regular screen. Change speed to something faster. See something, slow down to normal the re-play. The easy-out trick is in the video I think. He is an “STG” GM instructor. Have a good one! ASE Master Retired.
Sir you have given me the confidence to try and rebuild my trans in my 2002 bravada I know something about repair, but never tried to rebuild a trans before, your instructions are very easy to understand and very clear, I have all the tools to do it with and I will be putting my computer in the garage and follow you step by step, it's amazing, youtube and you. I just want to thank you for taking your time out to help many of us that has limited options. THANK YOU SO MUCH.
THANK YOU!!! I am stuck in Mississippi rebuilding my transmission trying to get back to my kids in Houston... this video was a great deal of help.. I can't thank you enough!! This is my 1st UA-cam subscription and I have been using UA-cam for years! You are a great teacher!.
I like this,...your detail explanation concerning the clutch, seals and housing was easy to understand, complete and perfect. I thank you very much.
Thanks I haven’t done transmission work in twenty years but I’m confident I will be fine. Thanks again for the advice
By far the best made and most informative videos on the net
Excellent great lesson of 4L60e 3/4 gear clutch assembly, very lovely impressive video, with soft sound.
thanks again. I will be rebuilding my 4l60e soon. its a 93 in a 2wd chevy truck with 280,000 miles. its starting to slip. this series of videos is very helpful.
Wow! It's amazing how long some of them last. Even at 280,00 miles, YOU can make it like new again. Thank you for the comment. It inspired me today while writing narration for lesson 6. By the way, since you mentioned that the videos are helpful, do you have any suggestions to make them better? I still have lessons 7 through 10 to write and film, so please criticize the ones I've done so far....and good luck with your 4L60E. Jimmy
Check out www.transmissionbench.com.
the videos are pretty good as is, can't say i would change anything. I've been a mechanic for 30 years but never attempted a trans overhaul. thanks again and looking forward to the rest
Transmission Bench Change Anything? No Sir, These videos are the difference between success and failure. I had a forward sprag that felt smooth as silk, and I was going to drop it back in. You said "take it apart and inspect it". I felt obligated to listen to you since you've done such a tremendous job. Sure enough the brass thrust was so thin you could see daylight through it. So, Thank You for these videos. Joe in Tx
Thanks.
You are an Great teacher and instruktør, now i want to start working on an 4l60e
Thanks for your detailed videos putting the seals in the reverse input drum was the hardest thing for me.
Two screwdrivers is what EVERYONE has to try first! Makes for a really good day.
Greatness, saved my butt At 70+ hard to remember stuff you read and did in 80s, then do it 2016. thank you, SS gets in , will get on board 5 week months are killers
THIS GUY IS SO GOOD AT WHAT HE DOES YOU CAN LEARN SO MUCH
Thank you so much for your videos
Since this video was made 9 years ago, there are a number of improvements to the 3/4 drum.
Rather than use the type of pistons that failed, use a SEAL-AFTERMARKET Hyper-Blu piston set.
When you take apart the input sprag assembly, if you find the gold washer set as pictured, discard the sprag and washer assembly and replace with an improved Borg Warner set. Also, this video made no mention of inspecting the back or the housing that has the 6 tangs. It should be smooth. If it has grooves, replace it.
When you do the air check to the drum (@30:32), first pour transmission fluid into the area where the spacer and bearing goes. Then apply air. Look for air bubbles. Check the other 2 apply holes and look for air bubbles. No bubbles, good to go, .... got bubbles, then tear down the drum, push out the shaft and re-seal the input shaft to the drum. By the way, nor was it mentioned about checking the drum for wear on the splines where the clutches ride. Look at 31:30. Below the lower teflon seal. Those splines should all be full with no wear. You can see in the picture where the splines are scuffed, but not worn. if the splines are worn, time for a new drum. Odds are you will not find a new drum any longer and will need to find a good used drum. But, yes, there are still new drums available, I keep 4 or 5 on my shelf.
And speaking of the 4 teflon seals, (also 2 on the pump stator) REPLACE them.
Super GREAT video
Thank you
You earned my Respect and subscription.
nice video, done at a good speed so can see what you are doing. Thanks for the time it must have taken to make.
My el460e clutches just went and now I will be attempting this very soon😁 thank you !
How did it go?
Joe you have made my life so much easier. Thanks for your time IOU one
you won a new suscriber sir!!!
Just a THANK YOU as your video was helpful.
Saved my ass man,thanks for excellent ,thourogh presentation
Very helpful and no shortcut..thank you
He is a great teacher. That gum must be great too, lol🤣
Joshua Rivera I knew I heard something
took me awhile to find this comment! The gum was in part 1 lesson 1 and then disappeared only to return on this vid, part 2, lesson 5. I'm not trying to do a rebuild - only just want to learn and listen to the gum chewing!! It drives some people crazy I guess - I thought it was a lozenge at first for dry mouth. Now I understand it's just all about street cred and "verga" as the Mexicans say....
OMG don't try to use regular snap ring pliers. It's nearly impossible. Use lock ring pliers, they are made for these type of lock rings and make it so much easier.
I used regular snap ring but holey hell it added many unnesseccary hours, libations and foul language
Your Exactly right ! Many HOURS ! Added time. Now after wasted time I took a chance and got out my imitation Dremel tool with a Cut-off wheel, I cut a tiny grove right past the end.... it worked first try ! Wish I thought of that weeks ago. Of course it only works for reassembly! Be careful u don't cut grove to deep
I'm watching all your videos awesome instructor
Absolutely superb videos. Very, very well done.
I just wanted to add that only 4l60 takes .060 inches of clearence as a minimum between the 3-4 backing plate and first clutch plate. The specification is .060-.094 as stated in the video. However, the 4l60e takes .035" to .083" of clearance. That info is per service manuals. I got on mine 0.45" of clearance for a 2005 Trailblazer. I just wanted to put this here if someone is not getting the .060 despite using different size pressure plates; saving you the hassle 😅 I experienced. Always check your respective GM unit service manual
I was wondering this because I replaced my 3-4 pack with 6 friction plates and 5 steels at .106” and the clearance was only .035” and it was all stock frictions and steels but the video somehow gets .60” clearance event though we supposedly used the same parts. I went ahead and changed one of the steels to a .076”, which gives me an addtional .030” or a total of .065”. I don’t mind being on the higher side.
@brittoncorbin7144 you are good there with .035 i would believe but take that with a grain of salt; i'm not trans rebuilder. Just a general mechanic. However, That's what the Trailblazer unit repair manual states and i have a GM unit repair for 98 and calls the same. I tested different plates and the best i could based on this video was .055. I left it a .045 though.
@@koffeegreaseaddicts thanks. Yes it’s a little confusing because this guy is the guru of tranny rebuilds and he said “it’s critical that the end play be between .060 and .085”. I take him for his word and you know he knows the GM specs so I reading between the lines that the end play needs to be a little higher than the factory specs, otherwise he would have just repeated the factory spec of .035 to .086. But then you research and watch the other videos and everyone aims for .035” which is exactly what I arrived at the first time!! The folks wanting the tight clearance claim it makes for firm shifts but the folks wanting the higher clearance talk about increased fluid flow, lubrication and reduction in temperatures. AHH. Very confusing.
hi i was wondering if someone could help i rebuilt my first tranny a 4l60e and put it in every thing worked just not 3 or 4th gear it would just rev real high like it was slipping but after taking it apart again i noticed my gap was at .105 and its supposed to be between .060 and .085 would this cause the revving problem it seem like it has to be it thanks
yes it would your are probably missing a steel or friction
or one of the shaft seals are bad or the 3-4 piston is leaking like a sumbitch. could be a lot of thing 4 yrs ago probably don't matter now.
Excelente, muchas gracias me fue de mucha ayuda, muy bien explicado
De Narda
This guy is like the Bob Ross of Transmissions.
I did use the .060 to .085 and .one is working fine but it looks like they recommend .025 to .040 so I don't know I hope it last my kit car with the alto power pack with 9 frictions and some different sized steels and another I believe top plate but I don't recall
How is your ride doing? I was only getting about .030” clearance so I I swapped one of the steels out for a .076” to get to the .060 to .085”
@brittoncorbin7144 it's totalled but it was fine till then
Thanks for letting me know my God bless you
Thank you VERY MUCH Sir , for you teachings !
God bless you !
Thanks, Jimmy
I've seen plenty of transmission performance companies that like to install 9 clutches in a pack and can go as far up to 15 stacked! Do they simply use thinner clutch frictions and steels to achieve this, or do the bearings and washers have to be modified as well?
Hey I have a 04 gmc sierra with this trans and a new process 246 behind it. Do you know if transmission fluid is supposed to come out around the output shaft on the transmission in between the transfer case. I have my transfer case out and just rebuilt it and noticed with the engine running fluid squirts out around the output shaft on the transmission. is this normal our do I have a seal leaking. Thanks in advanced for any advice.
Hi Tyler. This is normal. The adapter housing will have fluid from the transmission in it. If you look, you'll notice that the splined input shaft of the transfer case has a seal around it to keep the two areas separate. Jimmy
I've got my transmission tore apart and was not happy with what I saw. I paid 1300.00 dollars 5 years ago to have it rebuilt and all the clips on harness broke, harness shell broke in half valve body bolts loose . My main problem was 2nd and 4th slipping found drum burnt and band burnt , drum is ruined luckily I got one out of my practice transmission and harness is pinned the same just have to cut pwm solenoid out . Thanks again will let you know how it turns out .
Hi I got a ford freestar and the problem is : first of all , the van is driving and shifting perfectly but after 15 ,minutes every gear begin to slip. What do u think that is the issue jimmy? Thanks for your time and in addition, yours videos are the best
+Jonathan Nourian Hi Jonathan. The booster valve and sleeve in the valve body of these transmissions wear badly too. After the fluid thins out from heat, the pressure drops. Jimmy
bench do u have that repair kit to buy?
Hi. Unfortunately I do not carry parts for those transmissions. You might try calling Whatever It Takes Transmission Parts. Their number is 1-800-940-0197. Jimmy
thanks Jimmy appreciate it
What if the input housing has a few scuff marks around the top rounded edge of the housing (About 1/2 inch below the top where the splines are on the drum). The scuff looks like it is from where the reverse input drum sits on top of the input housing. Could the scuffs on the input housing be caused from that? Or maybe from 3-4 packs being burnt out, hence why my truck only had 1st, 2nd and reverse? Once my truck shifted to 3rd it was like I had pushed in the clutch but on a automatic transmission.
question on sprag thrust washer installation at 14:14 if I put the thrust washer as per your instruction, and install the 3-4 clutch pack and snap ring and I can grab the sun gear and it seems very loose, is this condition normal? If I flip the thrust washer and put it in the looseness of the sprag clutch assembly is much tighter but not and little loose.
Hi Jackson. It is VERY loose.This is normal. It feels loose because the assembly is actually supported by the sun gear and output shaft after the input drum is installed into the transmission.
thank you for your reply I have installed it as seen on the video
At 15:37, how is the input sun gear disassembled from the flat washer and collar?
just found this video...nicely detailed video btw! will the 4l60e rebuild videos help me with rebuilding a 700r4?
I have a 1996 impala SS, with that being said, the three pistons in the input housing are cast aluminum. Will the 1997 or newer steel bonded pistons work in the older style 4l60E's?
awesome job!
about the 3-4 clutch clearance, many people say .020 for the 3 4 to work best , is your measure of .060 to .085 a revised clearance . Maybe comment on what works best for high performance..... Please , nice videos , John
how much wear is acceptable on both journals on the shaft? I feel a very light step but I don't know if its really bad or not.
Is it recommended to replace all the steel clutch plates when you are doing a full rebuild?
Great video this is exactly what I needed I appreciate you taking the time of going step by step on it. One question please is my 1996 chevy 2 wd has no reverse or forward what should I be looking for when I get in the de assembly please and thank you
Hello Federico. If you have no forward or reverse, I would suspect the pump rotor has shattered. This is quite common.
As I view this video at around 16.20 or so, I see that the sun gear snaps in and out of the sprag race - with the need to use a hammer. On my 1997 unit, this sun gear does not need to be installed or removed from the race with a hammer, it is easily removed by hand... Is that normal? Is that a sign of excessive wear? or is this normal?
+Tom Joyce Hi Tom. This is normal. I explain in the videos that earlier 4L60Es don't snap into the sprag assembly. Yours will work fine. thanks, Jimmy
+Transmission Bench Thanks for the reply. Your video series on the 4L60E have helped me a lot on my project.
Please help Can you tell me why my truck will start off good will go from first second and third will not go in to fourth .. once it has went through first second third it will not downshift and if I downshift manual it only goes back to second if I shut off the it will go back to first and do it all over again
you never mentioned how the 1993 version assembly goes. its slightly different and i cannot continue and have to look else where to finish that portion for the 3-4 clutch pack assembly and im having a hard time finding info on my year 4l60e
thank u for any help u give
Why do I have to get my RPMS up higher than normal to get reverse to ingauge? All of my other gears work and the fluid is at proper level.
Great video.In My 4L60e,in my 2000 Chevy s10,I was driving and noticed it slipping a little.All of the sudden it quit pulling.Like it went to neutral.Next day it worked until it got warm,then nothing.What you think.
A Great Video and Instructions.
does the 03-04 input drum have an o'ring
Wish your videos would have been around when I rebuilt my 4L60E out of my 93 truck. But I haven't had any issues. I just ended up replacing the input drum with a hardened 300mm shaft that hopefully won't sheer at 600hp. And I replaced and the clutches and frictions. I've learned quite a bit from your videos if I ever end up having to rebuild it again. Is it ok to use a 13 vane pump on a 10 vane transmission? I'm just wondering because I put one on mine. Haven't had any problems just wondering. Also using a hardened welded sunshell and 5 pinion planetaries out of a 4l65E.
Hello I'd like to ask for your expert opinion on my 93 4x4 I have no 2nd gear everything else fine . What do you think my issue is? Thank u in advanced
Why is air coming out of check ball capsule in input drum very little when I apply air pressure to bottom hole??
you are the man..
I disassembled my drum assembly and was able to get the overrun piston out how do you get the bottom section out so you can access the 3/4 piston I don't want to damage anything and I talked to her in a little bit I just don't want to put too much pressure
Thanks so much for the help . You took the scare out of it for me. Do you know if a 94 transmission case is the same as 97 case, both without removable bell housings and if the electronics are the same .thanks again.
The wiring harness is definitely different. I do not know if they are exactly the same. If the channel casting passages are the same it will work.
I'm setting here watching valve body lesson at 8 o'clock in the morning when you replied lol. Just to let you know your my new best friend lol . I bought a core transmission for learning purposes . Thanks for replying so quick . Look forward to learning more from you .
I've been following your video I am going to try and get this fordf700 and when you put it in reverse it kicks out of gear in a hard pull what do I need to do
My 700r4 has aluminum pistons with the rubber seals, would it hurt to use the steel ones that also came with my rebuild kit? They seem to fit as well.
Question I was taught how to do Ford Transmissions about 40 years ago I haven't done one sense my question is my instructor told us to always rough up the steel plates with fine grit sandpaper and then clean them I don't see anybody doing that anymore is it not necessary please advise
Where can you get the different sized endplates?
And jimmy could this break something else in the transmission such as friction plate, steal plate...?
My new forward clutch piston went in housing with no resistance. I didn't need feeler gauges or anything. Will this be an issue?
It should have a lil resistance going in an coming out, its supposed to be able to seal.
Where do I get the correct overhaul kit? Mines a (94 4L60E one piece case) and I'm beginning to lose 4th gear. It's attached to a chevy 350 in my 94 chevy c1500 Cheyenne. I've got a pretty big parts list cause this transmission has never been touched except to replace the engine. I'm expecting everything to be worn out that you show could be.
I have a G 20 86 chevy van. Does your videos include my transmission?
What will cause a long 1st to 2nd ? No codes and not slipping .
So my 4l60e is a 1 piece from 94 the 3-4 piston spring set is different than what you show. Yours is 1 piece mine is 2 from the 94 version so im assuming i have to use old one??
do you have those selectives end plays in your website my end play its around the .040 what can i do to fix that .
+perverso12345 Hi. I don't have selective washers at this time. i'm always adding parts but I haven't gotten to those yet.
if a shallow pan filter is in a deep pan what could go wrong?
As long as it's kept full of fluid, nothing. But you are at higher risk of the filter sucking air, the dip stick won't help except at full
I am in the middle of my 4l60e rebuild. I order a power pack clutch set for the 3-4 has a total of 9 friction plates and 10 steel plates I can't not find a diagram neither could of figured out how to stack them up. I ended up placing a friction plate at first and a steel plate and so for a total of 8 friction plates and 7 steel plates my gap between the snap ring was over the 85 thousands of an inch. Any suggestions..? I remember at the end of this video you talk about the different ways of stacks but I went for the last one you said that in the middle of the stack to steel plates would be one after the other . You think that would work for me.
Hi Gilberto. It is extremely important to get the endplay .085" or less. If you cannot find a combination of frictions and steels to arrive at this amount, there are 3 selective end plates available. The thicknesses are: ,227", .192", and .157".
You already have one of them. Measure and find out which one you have and order the other two from a GM dealer or Transmission Bench at 706-414-9945. I hope this helps. Jimmy
It would of been cool to air test that clutch pack b4 dis assembly and show us that there was a major leak n the pack then diagnos the bad piston or broken seal or what ever else could cause that to happen
I have a 2007 Tahoe LTZ and lost 2nd and 4th gear.. With shifter in 3rd.. I have to rev out 1st and blip of the gas to shift into 3rd bypassing 2nd.. Still no 4th gear but can Cruz all day on freeway doing 85 just high rpms because no 4th.. Been driving Tahoe all day every day like this for 6 months.. Any thoughts would be greatly appreciated... Thx
Question on the forward sprag assembly. You show in the video to hit it out with a 1 inch socket, mine cones out by hand, does this mean its bad?! Thanks!
Jake Jackson yes
I’m confused.... the 3-4 clutch friction plates do not seem to be engaged to anything..... how do they transfer force???
the steel plates squeeze the friction plates as the steel plates spline to the sun case (or something like that). hahaha. Go to SouthPaw Autoworks for the BEST transmission "explain" vids of how they actually work - he even uses animation.
I'M HAVING TROUBLE . ITS LIKE THE CENTER SHAFT IS UP TOO HIGH, TO ALLOW THE INNER SNAP RING TO FIT. WE HAVE TACKEN IT BACK APRT TO NO AVAIL. ANY IDEAS?
is it just me or can i hear chewing threw the entire vid drives me nutz
very annoying!
Yes annoying
