    Do you have a custom tune?

    The T/H holds gears before the shift longer (except for WOT) and affects TCC lock-up. It shouldn't affect the firmness much or do anything at WOT unless the tune has been messed with.

    Its ok. In your tune, have shift pressures set to stock. You can decrease your shift times since you are installing a shift kit/servos, but keep all other tranny parameters in the tune stock. When setting up your 2nd accumulator, don't use washers. Just the stiffer spring.
