does any one here know if the allison line of trans in the gm trucks (gas or diesel) have the trditional bolt pattern on a sb/bb chevy? I know a guy that has a 5 speed auto and a couple of 6 speed manuals. the adapter for the isuzu 4BD1t/2t uses the chev pattern.I would like to use a manual trans in my van (it's a 5 speed now) just thinking that these are pretty much bullet proff so should work good:rasta:

If the trannys come from the new chevy trucks they still use the same chevy bell. If he got chevys 6 speed I would love to talk to him.
