I have done the NV swap in earlier trucks. Let me say I would not reccomend the NV4500 in a 1/2 ton pickup behind a 235. The NV4500 is a BIG transmission. I wouldn't hesitate to reccomend it for a 3/4 or 1 ton truck, or a 1/2 ton that has a high powered motor. This swap is more expensive than other popular transmission swaps.
