Check engine came on with an "unknown" code and a P0746 "Pressure Control Solenoid A Performance or Stuck Off" code. How difficult is it to replace this Solenoid which I believe is internal? Prior to the light coming on, the vehicle was running and shifting well. Now, from a very cold start (outside temperature in the lower 20s) the vehicle will go forward very slowly but moves. It is an automatic. Shifting from first gear to second gear occurs at a higher RPM (a little over 3,000). Once at operating temperature the vehicle shifts fine. The transmission fluid is clean and looks like it was replaced recently. Any further insight on resolving the problem is appreciated. Thank you.
