Re: Trannie Swap?
The 4.3 powered S10's used a completely different 5 speed than the 4 cyl and the 2.8 ones. The 4.3 ones use one with an integral bellhousing, wheras the 2.8 and 4 cyl.s use a non-integral bellhousing. The Borg-Warner T5 is not strong enough nor will it bolt up to the 4.3L. The 4.3 ones used an New Venture 3500(same as 1500 trucks) that was labelled as a Muncie.
