    Never seen a way within the tune, nothing is labeled for it.

    I've owned my 2016 Silverado for over 4 years now, I've had the grade braking feature turn on once in that time frame. Even when I tow trailers it never comes on, it just auto downshifts when I press the brake pedal like it always did.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    Only way to disable is to have it in Manual mode on gearshift. It activates every time key is switched on. No way to tune out....its a GMLAN communication between TCM/ECM and the SDM module (yaw sensor)
