I finally found a good video, that not only is for the same way I want to do my 4L60e rebuild! I gotta give this man the credit, and cant thank him enough! He not only covers the parts for this application of a 4L60e rebuild, but he is also very descriptive on how and why you wanna do it with the best intention and thoroughly cleaning your tranny as well as keeping everything in place! Keep making them videos, and god bless you man!

[@VeryGoodGarage]

Thank you so much ❤️, the video making shall continue!

[@raulmarquez2023]

Yes sir just what he said. Very nice job, thank you

[@marcgramke9461]

Thank you!! Awesome video really made it an easy process to do this.

[@juniorrodriguez8079]

Thank you for this great walk-through video, I watched this as I installed mine just yesterday. Cant wait to put it back in the truck with my new motor to see how it feels. Keep up the great work and videos!!!!

[@pdxgraham2442]

Very good information. I am soon swapping out a nuked 4l60e in my 03 with a fresh trans and will be doing a HD2 kit on the bench and this helped immensely

[@thelol1759]

Fantastic video, thanks a ton for publishing!

[@Lifesmasher]

My accumulator valve came out easy but my ISO-CONV VALVE did not want to come out, thanks for the walk-through man!

[@jnkfishing9274]

That's the wrong filter for that deep pan and it already had a corvette servo

[@Horner181]

I thought I was just seeing it wrong but you’re right.

[@josephlegocki6750]

thanks dude! used your video and got it done! appreciate the effort!

[@user-ku1wk1mk6y]

If this is your first time doing it I suggest go over information twice study it find the info watch a video and u should be able to do it the first time I did on my s10 it was intimidating I've done like 4 they are really easy once u get it it's like a walk in the park

[@luisvelasquez1797]

Thanks you I'm trying to start building my own thank you for your video

[@mrpunk01]

The shinny spring in the converter regulator valve already locks the valve to stop the gradual application of the converter lock up to fix the bore wear and fix the 1870 code

[@greasemonkeygarage1896]

That’s the wrong filter it will burn up the 3/4s! Plus it’s already pretty toasted with all that debris ! Metal bottom filters are for the shallow pans you have the deep pan ! You will burn it up ! If you haven’t already !

[@danielhall2982]

Loved the video getting ready to do the Corvette survo and shift kit any tips?? Keep on keeping on!

[@Raul-he5ii]

GREAT JOB MAN ! THANKS FOR SHARING YOUR WORK, WELL DONE !

[@BurningSteel69]

Can the 1st to 2nd shift be softened a little bit any by adjusting the linkage cables or any other way?

[@matermark]

I'm sorry I may have missed it, does the HD2 kit contain the same springs as the 7CS add-on kit that go internally on the 3-4 clutch spring cluster and others? (maybe Forward and Overrun clutches?) I was told instead of buying the HD2 to buy the SK and 7CS...

[@letsemailjoe]

Awesome vid! Thanks!!!

Good luck to you!

Does this kit help with towing?

[@andersoncruz9762]

What converter stall would you recommend for a 2001 Silverado single cab 5.3 with the same Trans set up ?

[@derucktorez2260]

If it's a stock cam then nothing to huge. But 2800 stall would probably treat you well. But depending on your rear gear that might not be the best option. Really depends.

[@mafosa8519]

hey bro! when you flipped over that accumalator. how the hell does the piston compress when the inlet hole is on the other side? weird huh? great share! larry

[@VeryGoodGarage]

You're guess is as good as ours, I'm sure you saw our visible confusion when we read that you were to flip that piston upside down lol

[@martinez1701a]

The 3-4 accumulator isn't needed flipping the piston with the sping just blocks it off, its common just to delete it you can stack two pistons or some kits have you pound a ball bearing inside the inlet but I like to tap it and put a set screw with a little lock tight. This also extends the life of you 3-4 clutch pack.

[@Goddess-illias]

I need to swap out my transmission in my 1988 Corvette I heard that a 700r4 will work I just wanted to see if anyone knows anything about that? Because the transmission in my car is not a 700r4 I think it's a 4L60 maybe. But anyway will that work do I need other parts to make it work or will my old parts works I think I heard it might need a longer drive shaft or something. I'm not sure can anyone help? I tried googling it but the information sounded kind of vague to me like there might be a bunch of extra work involved.

[@sKid-ts7hr]

Nice videos i bought the correction kit but didn't buy the corvette servo do u recommend to get the servo for my c1500 suberban 2wd same as yours . Also is the hd2 better im using my truck as family car or im good to go with the correction kit . Appreciate ur comment 😁 Thanks I subscribed by the way

[@VeryGoodGarage]

I could be wrong but I actually think most people usually just do the kit without the servo. I did it just because I thought, why not, but you can use either or both, it's up to you!

[@jhurst2289]

First time working on a tranny. This is very informative, extremely useful, and well detailed! My only question, you stated in the beginning you can change the servo with the tranny still mounted. How are you supposed to check if you can turn the input shafts if the tranny is still mounted? I apologize if that's elementary. Like I said, first time upgrading my transmission components. Thank you any, for your time, and I hope all here stay safe!

[@IZenI00]

@@BigNate9411 so put the truck in neutral?

[@Pinche_Gringo]

I'm not doin full race but do have a 2500 stall converter. At 28:37 do I still need to drill that hole to 101? And also would I need to use all 3 of the shims on the accumulator? I had only planned on street strip but cam requirements say at least a 2500 stall. Is that considered a high stall?

[@VeryGoodGarage]

I think high stall is like the 4-5k range, so I would say don't go full race on any of the steps that give that option

[@Pinche_Gringo]

@@VeryGoodGarage Thanks! And I broke the opposite solenoid trying to get the clip out hahaha

[@VeryGoodGarage]

Yes, that happens, we did exactly the same thing lol...

[@Pinche_Gringo]

@@VeryGoodGarage The plastic accumulator piston that you upgraded to aluminum how do I know which one to order? I THINK that I have a 2003 4L60E

[@SkitzWallaby]

I wonder if the 4l60e’s that are in commodores are the same as this or not

[@VeryGoodGarage]

Based on the wiki for the 4L60E, it definitely looks to be just a regular 4L60E. There's videos of people beefing them up in their Commodores

[@tynanwellington355]

this comment might get lost but is it possible to do this while the box is in the vehicle, i just put the trans in and don’t want to have to pull it back out 😅

[@jacquelynberry2789]

Great video man I'm about to put this kit in my 94 4l60e. Did you modify your PWM solenoid at any point?

[@VeryGoodGarage]

It was replaced because we uh, broke it lol, but it was just replaced with a new one

[@jacquelynberry2789]

@@VeryGoodGarage ah ok I didn't realize that was the PWM. Have you ever modified the PWM in other transmissions? I am under the impression that a solid torque converter lock up is more efficient than the gradual application of lock up with the PWM. Maybe I am misunderstanding this, i have only changed filters and solenoids before.

[@VeryGoodGarage]

I think I might have named the wrong solenoid, it could have been the one on the other side, the 3-2 downshift solenoid, but they weren't modified other than being replaced with just normal replacements, so neither were intentionally modified with something different

[@thefogisgone3662]

Yeah you can block the pwm solenoid valve so that its no longer pulse width modulated it directly applies and isn't as hard on your torque converter clutch. Isnt hard to do it all.

[@jacquelynberry2789]

@@thefogisgone3662 I'd like to do that. PWM seems like a dumbass federal emissions idea.

[@thefogisgone3662]

Good shit

[@jesseparadis6141]

What does the brass ring do? On servo?

[@VeryGoodGarage]

They adjust the servo depth and play

[@kiw14s]

Thanks

[@VeryGoodGarage]

Oh man thank you so much!

[@Subypowa]

Shouldn't you have used a different spring @20:08 being that you installed a corvette servo? the 553 was the stock piston.

[@VeryGoodGarage]

The corvette servo didn't match any numbers on the shift kit instructions, so we went with the stuck numbers instead. Main reasoning is that, we don't know why the different pistons require different springs, but if it has something to do with a factor outside the servo, then it would be best to stick with what marched stock.

[@martinez1701a]

@@VeryGoodGarage I think that spring firms up the band engagement kinda like what the 1-2 accumulator piston spring does thats why they have you drill it out to use their pin so if you want to change firmness of your 2-3 shift you dont have to drop the valve body to change the spring.

[@dfpfabrication9520]

Yeah the Vette servo is 093 so when I did mine I used the white spring and the shift felt good

[@beardedg500]

I have a 700r4 I'm having a problem from 1-2, I installed a Corvette Servo and the problem I'm having is that it shifts too late from 1 to 2 and so on...

[@timothythomas8024]

The shift cable is too tight , there's a lot of videos showing how to adjust it.

[@dougsavery5442]

I wana do this kit on my truck with the tranny in the truck how do you keep track of the check balls with the tranny in the vehical seems like they would fall out when removing the valve body can they be set in the valve body and re installed when putting the valve body back up in the trans/ or is there a way to get them to stay stuck to the plate or something

[@VeryGoodGarage]

I think you basically just lower the separator plate slowly, and when reinstalling you just have to set them in place and install the plate slowly making sure they don't roll out of place. Honestly it almost sounds harder to me to do the shift kit with the trans in the car, but I've got a lot of practice dropping the trans so to each their own I suppose

[@pacora07]

just put some transjel lube in each hole that will hold the balls in place while you put the valve body back, very easy and simple.

[@ByGraceThroughFaith777]

Tiny bit of Vaseline to hold them on place

[@thedavisway2717]

Can I take my old valve body out that has a kit and put it in a used 4l60 with the servo!

[@VeryGoodGarage]

I would only do that if that years of the transmission are the same, some things change between the years and I'm not sure what problems that could cause. Since it's just the valve body I suppose you could just try and see if everything still works lol

[@martinez1701a]

Very Good Garage is right they did make changes in the 4l60e from different years but the oil circuits in all 4l60e cases are the same. For example I have a 95 yukon 4x4, I can use any 4l60e and it will work fine as long as you keep the same valve body and separator plate for that specific year. The year will be embossed right next to the pressure control valve.

[@vindief0p]

You need to use the white spring if your using the carvette servo 🗣️

I'm guessing by too late you mean the metal in the pan? This was a super recent rebuild with a zpack, maybe it's just clutch material?

that does look like a corvette servo

[@VeryGoodGarage]

It's is lol, mainly for demonstration purposes, plus the old one wasn't transgo

[@chucksmith8200]

You put the pan gasket on WRONG. You covered the vent hole, it's just above the brake band accumulator.

[@VeryGoodGarage]

Could you refer me to something explaining what a "brake band accumulator" is?

[@chucksmith8200]

The servo he upgraded is a hydraulic piston that pushes on a coated steel band inside the transmission. The band surrounds the clutch housing and when the PCU "Power Control Module" senses a downshift or engine braking condition the servo extends which squeezes the band thus slowing or stopping the spinning clutch pack to allow what ever operation asked for. Go to KZbin channel Precision Transmissions Richard does an excellent job of explaining how transmissions work.

[@alh1007]

@@chucksmith8200 that’s the 2-4 band accumulator, not brake band accumulator. That’s also not how it works. Engine braking is done by the overrun clutches. The 2-4 band stops the reverse drum from rotating in 2nd and 4th gear.

[@savagebuiltperformance]

It already had a corvette servo lol 😆

[@VeryGoodGarage]

Lol you caught us... It was actually a different brand, the first one, but we swapped it with a TransGo branded one the second time. I don't recall us having a particular reason other than making it all TransGo

[@chucksmith8200]

I'm not a troll just a shade tree "monkey wrench" researching my own resto-mod. But my concern is that you might have covered up the 4th gear vent hole with the pan gasket.👍

[@deborahanderson897]

hello there, I actually bought the servo from Amazon and went to my local mechanic and asked him does he know how to put it on and then he said what is that! I showed him the video from KZbin to show him what it was, he still insisted that he didn't know what it was. smdh

[@darrinwatts9229]

Precision Transmission. Watch their videos. They teach you the right way to do it. Not some half assed way. Smfh

ive learned alot from precision transmission the guys daddy, all he does is take them apart but he will tell you from experience what to look for, but if someone is a complete noob they should be watching transmission bench i dont think that it would be possible to better present a rebuild video than transmission bench. alot of value in it
