32RH Transmission Swap From AX-15

[hear]

And yeah, the 2nd one looks great. The wobble on the first one could be misleading. The stack of crap that results in the input shaft location is really "balancing" on a thrust washer the size of a quarter. It has a little hole in it to center it on the nub of the output shaft. So if you're building it vertically, even when you have all the teeth on the frictions aligned, it will still wobble a bunch. It will wobble more if those teeth aren't aligned....but if they aren't aligned usually that means that the direct drum isn't seated all the way down, which will prevent the pump from fully seating.

Also, if you have that band screw tightened down there should be pretty much no side-to-side play on that shaft regardless.

From the other direction, that fiber thrust washer rides between the machined recessed face of the drum and the back side of the pump. Endplay means that those 2 faces aren't really in contact, which means the drums are kinda floating. I would 100% not send that as-is.

What is the status of that other transmission?

Unfortunately I think that is the one with a broken bell housing.

Looks like I'm headed to Colorado.

Can you be here by Saturday?

I started tearing down the spare tranny I have just to get a feel for it. It doesn't appear to be overly complicated like one would think, however, the margin of error to get things right is very narrow.

LOL, I have kids baseball on Saturday & Monday, and depending on how the NHL season unfolds today, I may have to be in NC to host an event at suite we have rented for Game 1 of the Canes/Senators series, which we won't even know what day the game is until later tonight.

I've tried to tell yall that these things are pretty easy on the inside. The valve body is pure black magic but you generally don't need to touch it. If you don't open up the drums then the only real variable parts are the thrust washers. Everything just stacks, its incredibly simple for such an amazing piece of engineering. How they figured out how to inject fluid from outside a spnning shaft into a spinning shaft and then selectively back into a drum that is spinning on that sameshaft, sometimes independently of that shaft is a real mind job. But you don't have to know anything about it, which is even more magical.

That sounds super fun, if it was the Avs you could probably convince Mike to come to you!

Here's the latest as I finally got time to work on it today. I pulled the oil pump out and found several things.

First, I noticed the paper gasket was cut but didn't think that was the reason for the leak since there was still an in tact O ring.

Second, I took a look at the bushing and noticed it wasn't staked at all. It was in there free floating like a spun bearing. It would move around by hand. So that led me to check and see if there is any damage to the actual bushing bore in the pump housing as well as check the torque converter input shaft the housing has just a little bit of scoring but I wasn't able to push another bushing in, so that's hopeful. The torque converter has some obvious chatter marks from the bushing. I called to see if I could get a new torque converter and everyone is saying several weeks out. I took some 400 grit sandpaper and smoothed it out as best I can.

Lastly, the seal didn't appear to be damaged (no obvious damage) and the retaining spring was still in tact.

My guess is that the bushing free floating like that took out the seal which in turn is where the leak was from.

I'm going to replace everything and use the torque converter I have and see what happens.

My seal kit just arrived so back to work.

And as I go to put the new bushing in the pump housing, I find I can get it by hand which is no good.

Luckily I have another one that I'll swap in.

Makes you wonder what other shortcuts that transmission builder took.

can you emery/crocus cloth that TC snout? I would hate to see it chew up the bushing and/or seal again.

The pumps should be swappable, use the pump from your busted trans.

I did use the spare pump and I did clean up the torque converter some more.

You just shush now...

I hope your experience with automatics is much better than mine has been . My most trouble free have been the A340F Asian and the aluminum Power-Glide .
I dealt with 3 no move failures in 4 months with a T-350 in a K-20 Suburban . I've only had the A340F with 230,000 miles since our great T-350 experience in 1987. They work good when they work , and If your playing in big rocks they make sense , however so many times they become a study in failure points .
I hope you can get this sorted out for your trip ! hang in there hosejockey !

Got everything back together just after dinner. Double check everything and it all looks good.

I added ATF, fired it up, and ran it for about 5 minutes...

....everything is good so far. No leaks. Ran it through the gears and everything is operating as it seems it should for no load.

Tomorrow I'll let it warm all the way up and then add more ATF as necessary. Then I'll throw the wheels on and take it for a test drive.

Here it is 10 am and no updates...

 

[hear]

did that endplay settle down after re-assembly? I don't have any reason to think it would have, but I'm hoping.

Well, it's 11:00 now Tyler!

So, it doesn't leak which is good. It doesn't make any odd noises which is good.

I fired it up to pull out of the garage and when I put it in reverse it took a second to get there. Then once on the street, I started driving off slowly and it seems like it was slipping. I go through all gears and they all have the same slip. In fact, when I got to the bottom of the hill, I almost couldn't get back up to my driveway. All gears felt the same.

I get home and reference the FSM and it doesn't really say much about this except add more fluid. I had already topped it off prior to going out, but checked it again and it needed more. I'm hoping this is a low fluid issue. I'm going to let it cool down before trying again.

I had adjusted the TV cable when I installed it, but not sure if this could be related to that or not.

I'm really hoping the tranny isn't bad.

Hang in there HJ . When everything is going south , it can get overwhelming .
