I just saw your questions about the rh32 swap, sorry for taking so long to get back to you. I'm sure you figured it out by now but just in case.
I used a 98 computer on my 97 with no issue but I cant guarantee that yours will work.
I used an external cooler from advanced auto connected to the factory tranny cooler lines. The check valve keeps all the fluid from draining back into the pan once the Jeep is off. My check valve is bad so if the jeep sits for a long time I put the tranny in neutral to build fluid pressure before tring to shift into gear.
