I have an 02 jeep librerty with the 3.7L V6. The engine needs more repairs than the vehicle is worth.. long story. I want to know what options I have for engine swaps and what would be the easiest and cheapest. I want a good DEPENDABLE motor for every day use. The transmission also has problems. I might as well swap the tranny while Im at it. Im looking for a known good strong runner with as few problems as possible.

Suggestions?
