I would hunt for a low mileage unit from a 95. That's the last year that fit's without having to change other parts. Be careful if the van has been hit in the front, the transaxle in the Caravan is prone to damage if it gets hit from the side. If you find one with a nice clean pan gasket and bright clean fluid, with 60-70 thousand on it, keep away. There were a lot of fast lube places that liked to change out the fluids, but they would put in Dexron with a "modifier" to supposedly make it the same as the Chrysler fluid. The problem was that it wasn't, and after a few months the trans would start slipping and having shift problems. The owners would find out the trans was going to cost 1200-1400 to rebuild/replace and decide it was better to scrap the vehicle. Saw this a LOT with fleet vehicles when the maintainance wasn't required to be done at a dealer.
