I have an 02 avelanche with service engine light on.

I had the codes read they read:

P0740 Torque Converter clutch circuit malfunction

P0785 Shift/timing solenoid malfunction

P1860 TCC PWM solenoid electrical fault

Can someone tell me if I could just replace the torque converter and other parts that read or does the whole transmission need rebuilt?

Thanks
Dan
