I'll have to wait till it comes back from the shop to check the gears; but i do have a th350 laying around that i had purchased for my regal but when my mechanic found out i had a th400 also he said i should run the th400 behind my motor, you guys think it would help if i had the 350 built and installed behind my motor. and as far as the q-jet my mechanic tuned it a little when i took it back; now i'm just trying to decide on what step to make next i think it's gonna be the gears how much do they normally cost?
