Inspection of a 904 torqueflite

What do you mean by it had .005 thou clearance.
You said the rings were locking style. I assume you mean that you put the sealing rings on the parking gear that slides into the output shaft support. Locking style sealing rings should be self adjusting.
Where are you measuring the .005 clearance?

It was a little crooked when I measured it. The actual clearance is .018 .....I was measuring the gap you see here to make sure it was the right ring. Pretty sure it is.
It was tight to even get it in there like that. The edges are sharp that they just catch.

When that ring is on the output shaft. It definitely doesn’t want to go in. I’ve put some pressure on it and turned it.

I did replace the output shaft support. The part number is the same.
I can’t even get the first ring into the support. They don’t want to compress to go in. Wi5 the trans on the floor and my full weight on it. Trying to wobble it back and forth. It still would not go in.

Given I don’t have a baseline for what this is supposed to be like with new rings. I can’t say if this is normal or not
