Transmission swap
Recently picked up a 72 cheyenne 4 wheel drive. It has a th350 trans. and NP 205 transfer case. Is there an overdrive trans that I can swap in with out major modifications and or any computer controlls. How would such trans compare strength wise. Thanks

Re: Transmission swap
Sorry to say that there are no overdrive trannys that will work without major modifications,
A the only non computer GM overdrive is a 700R4 and it is longer than your T350 which means, moving the transfer case and crossmembers rearward, then you have to deal with shifter issues, it will also need a longer front drive shaft and a shorter rear one,, Or another way is to move the engine forward, but then you have to drill holes for the engine crossmember, do exhaust mods, change to a different fan shroud, move shift linkage etc. OR go with a Gear vendors overdrive unit which bolts to the rear of the transfer case, the only real modication is a shorter rear drive line and adding a few wires, but it is the most expensive method. |
