torque converter clutch in '97 Grand Prix, help!

I've got a '97 Grand Prix GTP, and I'm getting a Service Engine Soon code (P1860) that says there's a problem with my torque converter clutch pulse width modulator (TCC PWM) solenoid circuit is acting up. How do I fix this? Do I need to replace the solenoid? The car runs fine now, but I don't wanna wreck the transmission. Anyone else have this code before? Please help!

If you are really expirenced with trannys go to a shop and by a transgo shift kit they come with a new valve to emlinate the PWM part of it converter clutch will work fine if its caught in time!!!
