I've been having shifting problems (no first, no 4th). Took off the pan, removed the solenoids, tested them. they both WORK (click click). However I couldn't find voltage going to either solenoid (but it still does a 2-3 shift) as I shifted through the gears with the ignition on. What I am looking for is a wiring diagram for the transmission. Unless someone can steer me to a better direction, I am going to try to look for a short or broken wire in my wire harness. I assume the harness goes right to the ECM? And is that behind the dash?

ECM is behind the dash on the passenger side. It's paired with the TCCM.
