Tranny Swap

I got a 94 s-10 blazer that a buddy wants to buy off me its a 4.3L Vortec A/T 4X4. We want to know if the tranny will fit in an older s-10 blazer its either a 87 or 89 4.3L 4x4 with A/T also. Looked in the forums but found nothing

no you cant just flop it in and run it from 93-up GMs transmissions are electronically controlled
