3.0 4-speed 95 Acclaim No Shifty
Finished up my drivetrain swap this weekend. Engine runs excellent, trans however fails to shift. I have reverse and 2nd (aka limp mode).
The car is a 95 Acclaim (originally 2.5L 3-speed).
The wiring is from a 92 Acclaim 3.0 4-speed.
The engine is a 95 3.0 (caravan/voyager).
The trans is a 93 4-speed (caravan/voyager).
ECM is from my 94 Voyager 3.0 3-speed (same part number as the 92 Acclaim's).
TCM is from the 92 Acclaim.
I'm guessing it's a wiring or sensor issue. I tried swapping TCMs with my van, to no avail. The TCM is good though, as both TCMs work perfectly in my van, so I'm ruling out bad TCM.
I tried a couple ECMs, again, no avail.
Trying to get some wiring diagrams so I can trace wiring, hoping someone has some idea to get her on the road.

95 Acclaim: Mild 3.0/a604 swapped, originally 2.5/3-speed.
