Hello new here. Hi everyone. Hope to find some help doing some foot work. Ok so I have a 2003 Ford Ranger 4.0l 4x4 Automatic195K miles. Engine has a cracked head. I got a 2005 Ford Explorer 4.0L 4x4 automatic 90k miles. Its been wrecked. Looking at putting Engine, Trans & transferase from the 2005 Explorer into the 2003 Ranger. The 05 Explorer has 4.0l wit 5R55S Trans. and BW4411 transfer case. The 03 Ranger has 4.0L with 5R44E Trans. and BW1354 Transfer Case. So question is what complications will I run into. I have both vehicles so computers, wiring harness, and modules all available. Thank You in advance. I have vin# from both vehicle's if needed.
