unisys12,

This is NOT the reason for the code.
The reason you are getting a code is because when you first start the car,
the PCM goes through a self test, and also tests and measures the resistances of all circuits.
The measurement taken on your TCC Solenoid is out of range.
This is why there is a code.
The solenoid may still be working, but to the PCM
the measured resistance puts it into a malfunctioning category.
