I parted out a wrecked 06 grand prix (non Supercharged) and need a transmission for an 05 impala (3.4) obviously the final gear ratio will be different but tuning can fix that here are the break downs for both trannys
if I can fix it with HP tuners i'm not too worried, can I make this tranny work in a 3.4 Impala?
