old manule tranny on 1996 318 help

Abodyman, the OBDIs do integrate to the transmission, but it's only to complain about lock-up on some '94-'95s and even the OBDII systems aren't too bad to work with.
Some OBDII equipped V-6 and V-8 vans had 3 speed autos, these vans had a plug in the O/D Lock-up wiring that give the PCM a signal that nothing is wrong.
It actually simulates the ohmage of the transmission solenoids to trick the computer into not complaining.

I'm working on finishing getting both wiring harnesses, OBDI and II ready for future demonstrations in cars and on an engine run-up stand.
Got a V-10 one in the works, too. It's only slightly more complicated to sort out.:D

In the end, it'll be about like adding an electric fuel pump and an orange box to an old-style points equipped Mopar.

Mark.
