Hey guys, haven't posted here in quite a WHILE, but I know you always manage to bail me out of these little situations I get in...

ok, so I'm rebuilding a 4L60E (basically a 700r4 with electronics) and I did exactly what I was trying NOT to do, when taking the valve body off... I have managed to keep all the check balls in their positions, except ONE... it appears to be the only one that goes in the casing side of the valve passages, between the plate and the tranny case. when moving the case around for a better position to work on the insides, it just hopped right out! I have no clue where it came from! anybody know of a diagram that indicates the locations of these things? like from a book or something? PLEASE HELP! this is for a friend and he's depending on me to fix this thing for him so he can have his wheels back... (I really shouldn't have been messing with the valve body anyways, but hey, I'm obsessive compulsive) THANKS IN ADVANCE!!!

There is one in the case, next to the accumulator bore towards the rear of the case. Here is a diagram of the check ball locations.

(yea, I cheated, ain't Google wonderful!)

damn...I thought I was good a google too...I don't know how I missed it!

THANK YOU THANK YOU!!!

I am not sure I understand your comment about not messing with the valve body.

Sounds like you are replacing parts in the trans , not rebuilding it.

I hope you are able to correct the problems the tranny had.

[gemini86]

ummm...yeah, all it needed was frictions and a band, so it's really not much of a rebuild, i figured i would replace the valve body gaskets while I was in there... but again, i shouldn't just been more careful...

what about the valve bore areas that wear out and need attention in nearly every 4L60E tranny? That is often the cause of burned frictions. Replacing parts does not correct the cause of the failure

Is this tranny a PWM lock up system or early design? The PWM valve bore area is always worn heavily .

Did you check for check ball wear on the separator plate and address it if needed. The 1-2 check ball wears out and sometimes the check ball blows through or sticks in the plate causing troubles.

Just thought I would point out a few items to think about.

good luck.

this one an early design...out of a 94 suburban. just about the first year they used the electronic trannys if I remember right.

het crosly just gotta love those guys that say only needed clutch plates.....

ok,so apparantly I'm in the wrong here. Tell me, since this tranny was slipping on takeoff, until it reaches about 40-45. what should I be focusing on?

thanks...

thanks...

the wear in the valve body bores, pump , boost valve , input shaft , bushings in the stator support, other bushings. Are the solenoids up to the job ? I replace the elctronics. Is the pressure manifold on the v-body serviceable?

You must understand that airworld and other tranny pros look at tranny over haul from the point of a complete rebuild since we must warranty the unit.

[airworld2]

ok sorry for that remark, but sometimes its what made the clutch on band failure is the what needs to be address, unless the plates are flaking off from high mileage. just look for signs of wear not just clutch and band failure.

[gemini86]

yeah I get where you're coming from, and I really can't see anything other than high mileage on this engine, I'm replacing bushings, o-rings, gaskets, everything that comes in this huge kit... the electronics look great, other than the fact that all the clips and stuff are fragile, I've already broken one of the harness mounting points... I am confused though, there's enough slipage and damage done to the clutch discs and band that I worry there is a problem with the apply pressure or main line pressure... it's been a little while since I've been to school for this, so I'm kindof refreshing myself as I go along... :S
