I have a 02 with a PPE stage five trans that has been in for about 5000 miles and PPE hot tune. Drove home the other day and noticed that when I put it in reverse that it felt like it was in a bind but moving. Drove home with no noises or problems for about 15-20 miles and Parked truck in driveway. Go to use it yesterday and can't feel it go in gear like normal but if its reved it will move forward barly and feels like binding in reverse and barly moves. Fluid good and level good codes P0700 trans system malfunction and TCC P1860. Cleared codes and tried to shift but same problem and only the P1860 came back as of now. Pulled pan and found no clutch material or metal. Ordered solenoid "F"...am I on the right track or wasting my time.

When the PCM detects a continuous open, short to ground or short to power in the TCC PWM solenoid valve circuit, then DTC P1860 sets.
