That is a 904 Chrysler built for AMC . It was used in AMC cars in early 80's in Sprite and others with the GMC 4 cyl Iron Duke motors . They had a lower first and second gearset - 2.72 and 1.54 instead of the 2.45 1.45 standard gears. As far as I know, everything is standard 904 internals. AMC also used the 904 with AMC bolt pattern behind the 6 cyl 258 motor. That's what I use behind the 4.0 in my Comanche. That trans will probably need the MOPAR converter.
