I have a 2001 Pontiac Sunfire 4cyl 4spd auto and is it possible to replace the Torque Converter Clutch Pulse Width Modulation (TCC PWM) solenoid without removing the transmission from the car?

Yes it is possible to do with the transmission in the car. You can move the side cover just enough to work behind it and remove and replace the solenoid. Don't worry about the gasket for the pan as long as it is the original one, they were designed to be reused.
