96 Caravan 3.3 4 speed time to replace the transmission oddly enough not because it's dead it has developed a lot of leaks and mileage seems not worth the bother at this point to repair it almost 340 thousand kilometers on it at this point the plan is to rebuild it later down the road.
The parts van the 99 has a build date of 1/99 which means it has the blade type connector the 96 has a build date of 5/96 which means it does have the TRS i did look at it it is the round pins now according to Alldata pin for pin they are the same i will attach a couple of pictures showing the pinouts .
If i am reading this right i should be able to cut off the connector from the 99 and just wire it pin for pin in the 96 harness and all should be well ? I understand the torque convertor/flywheel could be different but i wont know that till i haul it all apart and as i have the complete donor van it wont be an issue. The only other thing i am wondering about is should could ? i replace the tcm ? Use the 99 in the 96 seems like that might be the best move due to year to year improvements ? Also there was a dealer update to the pcm of the 96 the tag shows it was done on may 17 2000 but there are 2 stickers showing updates one shows 05003978ab as a part number and c1521 as a dealer code which i think is a tcm update ?
