    8L45 hardwired TAPSHIFT 2.0 LTG

    Hey guys,
    I am doing a stand alone setup on with the powertrain out of a 2016 Cadillac ATS including the 8L45. I cannot figure out the Pin in the TCM to hardwire the tapshift. Is there anyone that might have an idea of a pin to try? I have the diagrams for the resistors to use but not where the put it into the TCM.

    Send me your private email and i'll send you a diagram. It's controlled thru the BCM and data streamed to the ECM.
