I was going to keep the 5 speed but it seems like this board can't stand the older 5 speed because of it's durability so I was going to make it an auto. I would like to keep the 5 speed just because I miss a manual tranny but does the trans mount to the transfer case without new parts? I thought the spline count was different, and the length of the output shaft was different? I just don't want to put it in and then grenade it. I am just going to use it as a daily driver so I will not be going off road much with it. Thanks again for the help, I can't wait to get started!

Yes the same motor, 4.0. So your saying that the '98 ECU controls the trans so will I have to use that ECU? If so what will work and what won't? Thanks for the info!

I have a '87 2wd 5 speed SWB comanche and would like to swap the 4wd out of my '98 XJ cherokee classic which has the 4 speed auto and the 8.25 rear axle I think. The easiest way I can think of is to swap in the auto trans with transfer case and axles. The questions are: Will it be a direct fit? Will the computer in the '87 recognize the auto tranny/transfer case? And if not what do I need? Will the driveshafts fit without getting new ones? As in are the wheel bases the same? I bought 2 inch spring spacers for the front coils because the front end sits lower, are the 4wd springs longer? Should I buy new springs when I am doing this? I would like to update the gauges because I have the retarded HUGE fuel gauge if anyone has a spare with tach. I am also looking for a drivers side seatbelt in black for my bench.

I think this is what you are looking for. You will have to reference the parts because this is the newer valve cover style. The parts guy will hopefully be able to direct you to the proper old AMC style cover grommets. This was very helpful for me so I saved it to my favorites. http://jeep.off-road.com/jeep/article/a ... ?id=257985 The link is for a fix-it kit for Mopar because the design was flawed to begin with. For crap sake, just put in a simple PCV valve like every other car out there!!! Kevin

I am the proud owner of a '87 2wd short box comanche with the 4.0 5 speed and I would like to raise the front end a couple inches so the 30x9.5 tires don't rub and it would look better. I plan on making it 4wd sometime, but for now this would have to suffice. Any links on spacers would be much appreciated. I will post pics on the mild rebuild now, and later the whole enchilata. It was worth the trip of 14 hours driving in one day!! Gotta work ya know.
