Auto tranny Question?
The 94+ trannies have a electronically controlled valvebody at least on the b-body that was not the case in 93, 95 introduced pulse width modulation which underwent some changes for 96. This is not to say the tranny can not be made to work in other years just that there can and will be issues with some interchanges. The OBD1/2 thing means almost nothing to this.
