Thread: Trans Tune off or bad TEHCM / Valvebody?

  1. #1

    Question Trans Tune off or bad TEHCM / Valvebody?

    Just need someone who knows that can look at the log and confirm the issue.

    Tune off or bad TEHCM / Valve Body?

    When the car is not up to temp on a cold start, it wants to stall when I put it in D from P, wants to take off because it feels like the converter isn't slipping much at cold start idle, and pulls through the brakes.

    Once warmed to operating temp, that all improves, but it still pulls hard when stopped in D.

    It also is jerking / slamming the 3rd to 4th gear shift I believe it is.

    Issue carried over from the 6L80 to the 6L90.

    Circle D 6L90 LS Pro Series Stage III 258mm 3B 3200-3400

    TEHCM / Valve Body is my OE 6L80 swapped over to the CTSV 6L90.

    What issues did you have?

    The shift issue I had before the swap.

    The converter pulling is a new issue.

    I have the same stall, but went from a sigle disc to triple disc because I'm making 760rwhp now.
