    6L90e TUTD issues

    ZL1 Camaro with intake and exhaust and its having issues in TUTD mode. WOT 4-5 shift will go straight to redline if the shift is performed before 6krpm. I'm not really sure what its doing and the local shop can't figure out the issue either. Tune is posted below. 14 ZL1 Auto Herder Tune Intake Exhaust.hpt

    Same issue on the trucks, as the Camaro & truck TUTD switch goes to the BCM. The Corvette TUTD switch goes directly to the TCM. I can get the Corvettes to up shift & downshift at any speed, but not the Camaros or the trucks. Support is aware of this, no ETA.

    I made a few changes and now 3-4 and 4-5 are fine, but now 2-3 is acting up. very frustrating. Hopefully we get more info on this soon.
