I will hopfully be picking up my donor this week for my 4.0 swap. But I was wondering how difficult would it be to drop my old 2.9 in the Explorer? Was thinking about keeping it instead of scrapping it out. I know if I completely swap the entire wiring harness, I should be fine with the motor and interior, but my B2 is a 5 speed and the Ex will be an auto. Will that cause any issues?
 
Changed the flywheel on the 2.9 to the 4.0's flywheel/flexplate and you'll be fine.

later,
Dustin
 
K thanks. I was planning on using the 4.0 flex/torque conv on the 2.9 since I wont need it.
