TCC Wiring Help, 4l80E
TCC Wiring Help, 4l80E Been trying to troubleshoot my tcc lockup circuit and have a bit of confusion on how the TCC wiring is supposed to be from the factory. 6.0/4l80e engine/trans/harness out of an 04 2500HD pickup, 2wd. I reworked the harness and am second guessing myself.
I have +12v on blue connector pin 33 with brake OFF, and lose the +12v with brake ON as it should function
I have a wire on green connector pin 2, this is the PWM TCC solenoid valve control.
I DO NOT have a wire on green connector, pin 42, TCC solenoid control.
Is this correct for my setup? If it is, can i ground green pin 2 to check function of the the TCC solenoid? I do have a transgo hd2 kit installed as well.
