32RH will not move in forward gears

[hear]

The FSM has a whole process where you pry up the clutches and use a gauge bar/dial indicator. I've never done that. I just jam a feeler gauge under the snap ring.....I didn't invent that on my own though, maybe that's what the ATSG says to do? I can't remember now. I just looked through the FSM for the 97 & 02, and neither describe it the way I do it. It must be in the ATSG then, which I can't seem to locate.

The rear clutches are used in every forward gear under all circumstances. The air check will verify that the clutches apply, but it doesn't mean they will hold. When you did the rebuild, did you check the clearance between the pressure plate and the snap ring on the clutch drums? I forget which one uses the wavy snap ring, but if you checked the clearance under the low part of the wave you'll be out of spec and possibly have trouble applying enough pressure.

The input shaft sealing rings are part of the air check (the air routes through the input shaft and gets to where it needs to using the sealing rings. So if those were bad I would think you'd see it during the air test.

The overrun clutch is not used in M1, so if you don't have any movement in M1 then something else is wrong. But if you have Reverse then the low/reverse band is ok, so a missing M1 places the problem elsewhere. I mean, M1 only uses the rear clutch so no M1 really points to the rear clutches.

But is it a friction problem, or an ability to apply full pressure problem? You can run a pressure test (detailed in the FSM) but I've never done one. The idea of having the Jeep up on stands while the wheels are spinning is somewhat unsettling. I guess I would triple check the fluid level (running, in Neutral), and then steel thyself for an afternoon of transmission dropping.

In your excel sheet, is Direct meaning third gear?

I am still dealing with the obscure and intermittent failure to drop out of third when coming to a stop.... its too intermittent to tell what I change fixes the issue......


It has turned into also an intermittent bucking/near engine stall with reversing down a steep hill (My driveway) on a cold start (Also intermittent as hell) so its leading me to believe there is something up with the front clutches not disengaging properly until near operating temp.

Any ideas?

Yes, direct is 3rd gear. Input & output are directly connected for a 1:1 in/out ratio. My first guess is that your TC isn't unlocking. Have you tried unplugging the TCC lockup and see if it still does the same thing?

Thats the thing, its so intermittent that even if I did something it wont occur again for a while.

Last time it happened was a week or so ago and lasted 2 days, time before that was 3ish weeks ago and lasted for a day. when it occurs again, ill unplug the TCC lockup and drive for a bit to see if it happens again
