    6l90e tcc settings for dummies LOL

    can someone help explain what to adjust with my tcc settings? looks like my tuner left slip still at 20 rpm.

    They left the lockup function on in 3rd - 6th gear....
    So gears 1-2 just ignore, it'll never lock up
    I'd get rid of lockup altogether in 3rd gear - it's kinda silly to have it in normal/performance situations.
    Then drop the slip in 4th-6th gear down to zero... I left a little bit of slip in at low rpm/low power and scaled it from 5 down to 0...
    You could also benefit from keeping the transmission in the lower gears a bit longer as it upshifts at mild acceleration...
    Of course you will have to change the lockup engage/disengage accordingly

    Nothing wrong with leaving the slip tables alone in most apps with a stock converter.
