I have a 1965 Rambler with a complete drive train from a 2004 Jeep Cherokee inline 6 cylinder 4.0, including ECM & ABS Module. It's a build I did a few years ago and it recently came back to me to repair some accident damage and body work. When the car was picked up, we discovered it wouldn't go into high gear. After getting a P0500 code, I found the ABS Wheel sensor was not getting any voltage, even though the ABS Module was getting 12V from the Bat and Ign. The Rambler only uses the ABS Module to control the transmission and not braking.
I've tried using another used ABS Module but got the same results. Is there some signal that the module isn't getting that is preventing the voltage going to the sensor?
Thank you for any ideas

That is some impressive custom fabrication!
