    Default Tutd tap shift 8l90e stand alone wirring diagram for gm connect and cruise

    Gm connect and cruise has a tap shift option for 8speed auto I have the trans and engine calibrations and engine harness diagrams. But not the transmission harness diagram? Anyone know what pin the tap shift goes to, on the trans and or tcm?

    Hopefully this will help some, while it doesn't list the pinouts per say (i'm guessing that the harness is labeled?) it does tell you what ohm resistors to use for the TUTD feature...
