    I lower {raised numbers} line pressure in the lower areas to calm down my downshifts.

    Also why it will only apply converter LOCK on first gear?
    i dont like how it feels with the converter locked at low speed,instead i tried to lock at WOT, but looks like only locks in first gear?

    Yes PCS table. I've been struggling with the lock up. There is a file that 300c made that has the tables conversions that help with lockup times.
