According to my Haynes manual, Code 83 is defined as "Reverse Inhibit System" (manual Trans, 5.7L0 "Vehicle must be operating under 4mph to allow reverse selection." Doesn't sound like it's your problem if it's for maunual trans... Sorry.

DTC 83 - Reverse Inhibit System (Manual Transmission) <<<<<<<<<select>>>>>>
DTC 83 - TCC/PWM (Auto Trans)

It has somthing to do with your torque converter clutch, either its not locking up or its staying locked up when you brake or somthing else. Im not sure what PWM means, mabye, pulse width modulation? The 4L60E does pulsewith modulate the accumulator pistons, is could be somthing to do with that.
