Yes, the high side of normal but OK, it's within manufacturing tolerances. The new P-code you are getting is a mechanical problem with the solenoid, probably will have to pull it and take a look.

The second code seems to describe your problem

The P0756 code is detected when the ECM has detected a mechanical fault with the solenoid energized, valve stuck off
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Transmission will not shift gears.

po756
p0720

High rev in reverse to get it to move.. which is most likely the torque converter code. Do you think the p0720 speed sensor would cause all these to be thrown?

Imho, no way did all that stuff fail overnight. I'd be suspicious of a fault in the wiring harness or the TCU itself. If you clear the codes, do they all come back?

Yes i cleared them a few times last night and they came back. Do you think the p0720 transmission speed sensor is linked to any of those other codes? The symptoms i have are some of the symptoms of a bad TSS.
