Inspection of a 904 torqueflite

Here it is.....slid back-

This is causing the reverse drum movement I was talking about.
It’s not quite 1/4” but it’s a lot.

It moved like this when the trans was assembled in the 999.
I didn’t check it in the 904 assembled

This picture is of the 904.

I think he reverse drum is allowed to move back and forth like this. But I can’t say it’s fact as I didn’t check the 904 before taking it apart like I did the 999

Also......with a 3.8 kick down and the larger band
A double wrap reverse band.
87 transmission.
I need to be sure of the adjustment specs on both of these. I’ve seen several different ones. Might be why the reverse band did what it did. Could have been set for an earlier 904 or something. Like 2 turns out instead of 4 or 5 or whatever it is.....and they set it too tight. So it wore down the reverse drum
