Inspection of a 904 torqueflite
I haven’t measured the end play yet. I did tug on it to see if it was tight or excessive. Seems fine. I’ll formally measure when I get a chance. My guess is about .030-.040
On the 904 to set the bands. I adjusted by sight. The valve body was still off and I just loosened it until I saw it just barely start to spin freely. Then backed off 1/2 turn and locked it down. Is this acceptable?
However: the second assembly on the 999 has stalled to a point where I’m beyond how to go about it. I got to the point where you put the small snap ring on the output shaft. It seems to have excessive play.
The slot where the snap ring goes is about .097-.10
The snap ring itself is .042
Nothing seemed right. I remember this being a snug fit.
The other transmission is already together. I’d hate to pull the pump and take it all back apart to double check the fit on that one but I do know it fit like it was supposed to. Everything about the 904 transmission went pretty smooth.
I know the thrust washers are all present.
The things that were replaced were the output shaft support, the output shaft itself....which was exactly the same....
And the sun shell....which is exactly the same.
The new sun shell used my original gears and shims.
So I took the old output shaft out of the box. The snap ring slot was the same as the other one.
I put the old sun shell back in. Same result.
This snap ring is the selective snap ring that goes all the way to the front of the shaft. I can buy a thicker one but the problem with all of this is....
Why is it different? What’s changed to make the old snap ring not work.
This one is beyond me so far. I’m pretty confident in a lot at this point. I know what goes where and how it is all supposed to fit. I am pretty sure the 904 is fine.

This is how the 904 fits. This is not mine. I pulled the picture from online.
The 999 is way more loose than that.
