A904 renew w/pics, tools

Kit, Thanks for the detailed writeup. It will inspire others to try this scary but very do-able job.

I also wondered about why 5-1/4 screw turns to adjust the rear band in my 64 Valiant's 904. It was answered by a knowledgable FABO guy w/ a link. That was because that band had multiple wraps. Later bands are a single piece, which is what I see in your photo. For that band, you should probably back off 2-1/2 turns or whatever is correct for later trannys. If already assembled, I wouldn't worry, and just adjust it correct on the next filter change (~100,000 miles).

I haven't done a 904 yet, but rebuilt my A-413 which is the FWD Torqueflite version of the 904. Indeed, it looks more like yours inside than my 64 & 65 904's do since it has the internal parking rod (instead of external cable) that probably started in 66. To remove the front pump, I just screwed in 2 bolts in the tapped holes until they bottomed against the case and tightened evenly to push the pump out. Did the same on my Mopar 604 tranny. Might work on a 904 & 727 too.

Besides long snap-ring pliers, the only special tool I used was my shop press to push in a metal piston to get the snap ring in. However, that spring is weak so could have done it by hand with a helper.
