A: The bolt pattern is the same as Chev 2.8L V6. Transmissions (stock) are AX-5 5speed (commonly 2wd in Comanches) 904 auto and AW4 (but lighter duty). Other possibles are AX-15 (from a Dodge Dakota with the AMC 4 cyl. Not sure what years) and any Chev trans that bolts up to the 2.8L V6 (with some mods for the crank sensor if EFI and zero balanced flywheel). 700R4 was used in some S10s.

That's been thought of here before, and I think it warrents another look. I'm sure a boosted 2.5 would go great in an American. What I don't know is what kind of transmissions will fit behind that engine? Does it have the same bellhousing pattern as a six, thereby letting you put a good variety of stronger transmissions after it? Jim Boone Mims, FL
