Dr. Lee,
My "Raptor" had a temperature sensor in it and that was what was causing the converter not to lock. When I was coming back from Las Vegas on a trip when it was really hot, the torque started locking up. It was too late for my transmission though and I believe that trip was the demise of my tranny. The turbo 400 is back in it now. tpitt
