    Good morning all
    i roadcourse my 2018 a10 car and as you can imagine heat is an issue .

    Did anyone experience HESITATION
    On the 10r80 when higher temp (around 230f) is reached?
    I paddle shifting on track (but it also happened with full auto)
    Hesitation is like when in a manual you push the clutch ,shift, and push the throttle BEFORE releasing the clutch .
    I have a small video ..it is hard to hear but please let me know what are your thoughts on it.

    That is strange. 230 is not even into the hot range on the gauge. 255-260 is.

    I had to do quite a few logs to get the shifts dialed in @ wot. There was random hesitation occasionally till we tuned it out. My trans temps have never gone much over 215 ever. Not road racing either.

    Have you logged transmission pids during laps for your tuner?
