Jeep AW4 Transmission Controler

This transmission is controlled by solenoids. The controler turns them on and off in sequence, to change gears(the PWM outputs in this schematic), depending on load. To over ride, install a 3PDT relay or 3 relays. Each solenoid is 1 common pin on relay(lamp in this case) then a second switch switches between N.O. and N.C. of the relay/s. I have it set so on the normally closed side, so the TCM is normally closed. In case of relay failure the TCM can still do its job. Switch on the left controls what powers the solenoids. The 3 switches on the right control the solenoids when the switch on the left is closed. When open, the TCM (PWM outputs in this schenatic) control the solenoids(lamps).

I could not get relays to switch. The light came on When I closed the switch.

I updated the description a little better. I only make these when I can't sleep lol
