Inspection of a 904 torqueflite

Where did I mess up the terminology that time?

I did distort the shell. I didn’t remove the sun gear before pressing in the bushings. It bent the shell some.

I had a spare 904 shell sitting here. It spun more true than the one I warped. That’s one way I knew it was warped. Had suspicion anyway but that confirmed it. So that one is now sitting in the 904 and it’s good to go. Took the gear with the new bushings and pressed them into the spare shell.

The 999 is warped. I have to replace that shell I’m pretty sure.
Those mistakes I can control and learn from.

The reaction shaft bushing.....I don’t know why that’s compressing so badly......
And compressing in the middle. Not the end like I would suspect. It’s literally mushrooming evenly in the middle of the bushing. Leaving a ring and not allowing the bushing to sit in the race....even loose it won’t
You should not have to press the sun gear into the sunshell.
Those parts should all just assemble freely by hand. Make sure you put the thrust plates and any spacers if any back in the right locations.
