It is labeled the TCC/PWM solenoid so it was probably looked up right. The part that you likely found on the back passanger side of the trans near your oil filter is the VSS, vehicle speed sensor, and has nothing to do with your code. As I mentioned above the solenoid is likely not the cause of your problem and the electrical end of the actual TCC pressure switch needs to be diagnosed. The TCC pressure switch is not the same as the TCC/PWM solenoid, they are two different parts.
