Just to lay it out for the future....
Picked up a sweet 5-speed out of a 2001 Trooper a few months back out of the U-Pull-It in Albuquerque - just over 100k miles on it. Yep - planning on the manual swap at some point. That was a bit of a shame - a VERY clean Trooper. Looked like a Soccer Mom car... It was a tough call not to pull the engine as well, because it was probably a VERY clean option. But I just don't need it. (I hope!!)
DEBATING a diesel swap. Very practical here in NM. A lot of dollars. I would probably go the Bighorn route, but that is a chunk of change... And I want to do some reading first to see what the transmission gearing on those Bighorns looks like, or if I decide to go that route, do I want to try and buy an ENTIRE drivetrain... If I do, I'll have a Trooper trans up for sale! Will keep you all posted on that when I make that decision.
