Now look at this....I can slide it back this far. This is what it is like in the transmission wen the stack is installed.
The 999 1/4” play is this....or identical to it. I think it’s normal. -
So.....if all this was normal......and let’s say the output shaft sealing rings were still sealing...l.which I think they were.
No clearance issues.
What would cause the reverse drum to wear like that......
