I had that happen to me once before and it was a solenoid that wasn't plugged in at the valve body. But, since you had the valve body back out I don't know what it could be.

V2 may nut cut it for hidden codes. You will need to moniter the data stream and look at all the solenoid parameters, speed sensors and such to see what is not working. It's there; you just need to find it.
