32RH will not move in forward gears

[1965vwvert]

I just completed rebuilding my 32rh for my 00 TJ and will not move in forward gears. Reverse works great so feel like I am missing something.replaced rings, seals, plates, bands and cleaned valve body. Checked fluid level running in neutral and just a hair over full. What am I missing? Why would reverse work so well but not forward? Seems like I am missing something simple. Thanks for any help

Rear clutch maybe? You air check everything before re installing the vale body?

The rear clutch is applied in every forward gear.

I did not air check it. Not sure how I would?

Thanks, I missed this in the fsm. Al least I won’t have to pull the trans to perform!

I thought I made a video showing how to air check.... I know I recorded me doing that during my last rebuild but I can't find the footage. Not that it's hard to do or anything. Much easier when it's on the bench instead of dripping on you though.

The air test was good, looking for other ideas. Seem really strange that reverse works so good but not drive?

If you can verify 1-3 are for sure not the issue, you may have 5 and 6 to look forward to

Didn't think I could attach a PDF, so here ya go

Good stuff here too.

Does the shift cable need adjustment? I know my 42rle needed adjustment to get in all the gears.

Shift linkage is correct, start in park and neutral.

1-3 were good, I guess I have some more work to do.

4. rear clutch failure

5. Transmission overrunning clutch failure

6. Input shaft seal rings worn or damaged

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.

I did not check the clearance. What is the clearance supposed to be?
