Correct, TOD is under the carpet, but you need either a 98 or 99 Trooper ECM; 2000+ went to drive by wire so those ECMs won't work.

My swap is still going strong after 50K miles, but I'll probably need to do a rebuild on the AR-5 soon because the synchros are going out (tends to "fall out" of 5th gear with no load on the engine). That's no fault of the swap of course, it's just the 150K miles on the AR-5.

Good luck.
