Situation: 1982 Jeep Cherokee Wide-Track restoration---

Components: Stock 258 cid engine and T-5 transmission;

purchased AMC 401 V8 (without intake and exhaust manifolds, carburetor, alternator, and a lot more ).

Problem: Choosing a transmission, preferably one with *overdrive* capability, to mate to the AMC 401 V8.

Options: NV4500 manual 5 speed (fifth gear is overdrive);
GM 700R4 automatic overdrive (fourth gear is overdrive).

Additional considerations: NV4500 adapts to 401 with a bellhousing kit and an adapter from Advance Adapters or Novak Conversions and mates to the stock NP208 transfer case via the 23 spline output shaft.

Not clear about the 700R4---> Novak Conversions lists a kit for the 304 and 360 engines, but not the 401. Novak Conversions has replied that I will need a flex plate for a 401 that they can take and modify that will then work with their adapter.

Both transmissions appear to be tough, truck transmissions when the 700R4 is beefed up for heavy duty and 4X4. NV4500 is heavy duty by design.

Both are comparable in price. Which to choose? Which is easiest to install? Which will provide better gas mileage?
