Hi.Does anyone here have personal experience with such a swap? I currently have a 2500 GMC P.U. with a 435 4sp.and the old knee is starting to complain about the clutch duty.So I want to put in an auto,either a T.H.
400 or a more modern unit (must be very heavy duty).-or even a 400 with a lock-up. Question 1) How much work is involved? " 2) Is there a trans.better than a 400,perhaps with lock-up converter or even 4 gears,that I could put in there? Currently has a 350 motor,3.73 rear,used to haul large loads. Thanks a lot !......Brian O. ********************- posted
