    Speeding up downshifts on a 6R80

    Is there a way to speed up downshifts on the 6R80 from say 6th to 2nd for example? My car takes around .8 seconds to command 2nd gear after going WOT.

    There are no 6>2 or 5>2 tables so what are used for these?

    Mods are in sig.. Thanks

    Knock Retard is the reduction or prevention of knock by lowering ignition timing:

    (+) Adding Knock Retard = Reducing Timing. PCM is seeing knock.
    (--) Lowering Knock Retard = Increasing Timing. PCM isn't seeing knock.

    Thanks. Yes this is part of what I did to get my upshifts to shift faster.

    For some reason I didn't notice 6>2 so that will work for that shift but what about 5>2? There's no 5>3 but there's 5>2 and 5>4 lol. Does 6>2 also cover 5>2?
