A904 high performance rebuild--advice wanted

hmm i dunno...i'd stay with a 904. they are a wonderful transmission, easy to build, yes lighter, and of course take less power to operate. especially for a small block car, a 904 is a perfect match. they can handle a great amount of power.

when my brother and i built mine; i used red clutches, kolene steels, a heavy duty band strut for 2nd gear, 4.2 lever, heavy duty semi rigid front band with red linings, low reverse band with red lining, and of course new rollers and springs, new bushings. For a shift kit we used a transgo tf2, with a PTC 3000 stall converter. I used a summit brand aluminum deep pan, and an external B&M trans cooler.

use chrysler/mopar at4. its a good proven trans fluid.

just an example of what I have done to my 904, behind a hot street 318.
