    Tow mode

    I have an 07 Avalanche with tow mode. I have a friend with an 05 Trailblazer that does not have one. He uses the truck exclusively for towing. He wants the trans programmed to run like tow mode. I have compared the tunes and can not figure out exacty what the button does to the tune. Any help would be appreciated!!

    I just checked a stock tune for a 2005 Silverado 5.3 4l60e. From what I see, the Tow/Haul mode (performance mode in HPTuners) has slightly higher upshift speeds at part throttle, quicker shift times, earlier TCC engagement, and more torque management.

    I have attached the file I was looking at to give you an idea.
