A lot of the GMC's used the New Process trans. You can ID them they have an alum. top cover. It's not as good a trans. as the SM420. The V-6 used a recessed flywheel & a clutch of it's own. They are hydraulic operated.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
