    You do realize that enabling the trans brake is going to break your transmission right?

    You can get a good pass without the trans brake and not break the transmission.

    Your car, I’m just sharing what I know.

    I sound like a broken record sometimes but trans brake = broken transmission

    I personally won’t enable the trans brake for anyone I tune or help. I explain what I know and if they chose to do it, then it’s on them.
