I just got my ECU back from Tork Motorsports and am already having problems. I am about 75 miles into the "re-learning" period and now my car is stuck in 4th gear with a P0753 code (shift solenoid). I don't know if this is related to the tune or not. I have called Tork but they are closed today. I have also disconnected the negative battery cable and re-seated the connectors on the ECU with no change. Any other suggestions?
