the transmissions use different electronics and pcm programming is different 94 vs. 95
programming is different l99 vs. lt1
if you swap you will need to use the correct programming on the pcms or you will have problems.
programming needs to match both the engine&trans.
you can reflash with usb cable and laptop with EEHack.
'94 Caprice Wagon - Bilstein shocks, Hotchkis rear trailing arms & sway bars, Moog 80098/CC623 springs, AR Torq Thrust II wheels w/ 255/50/17 tires, Bonneville seats, and a LOT of new parts. Some day it'll be done...to do Jegs Catback exhaust & 24x conversion
