700R4s aren't as durable as the 400. Don't get me wrong, they are still good transmissions. If I were you I would do the conversion, but I would find a new or rebuilt 700R4, add a shift kit and an large transmission cooler. Then you'll be set and right gear ratio will give you much better highway mpgs.

With conversion I mean swapping out the 400 for the 700R4.
