    Speeding up WOT shifts on 6R80 / 6F55?

    I''ve figured out how to make the WOT shifts engage better with less/no noticeable slippage, but I haven't been able to figure out a clear way of speeding up the shifts at WOT.

    During light throttle to medium throttle, my 6F55 feels very seamless almost feeling like a CVT. At WOT, the increased upshift line pressure makes the shifts very pronounced and noticeable, but the shifts need to be a bit faster.

    Any ideas?
