I'll bet you need a line pressure bump and PWM eliminated. The more you drive it the more hurt its gonna put on that thing until the clutch is gone.

you think bumping the line pressure up and eliminating PWM will stop it? really it just grunts when going into lock-up, its hard to hear over the exhaust even with the cutout closed...

PWM applies the clutch slow/soft and this can let it
bounce / chatter some until it clamps down fully.
It's an easy enough thing to try, setting the TCC
min duty to 98% and see. Line pressure at low load
is probably commanded to 0% (which still has some
base pressure, but gets lame for load holding as far
into the throttle as 0% persists). You probably want
to bump either the base pressure, TCC applied modifier
(if this is available in your tuning tool) or the low-line%
force motor current can be scaled back if not. You
would still see 0% commanded but 0% means more
base pressure, like.

I have the Fuddle HP/street version, run with both
of these things done (artifacts of the last converter,
which needed all the help it could get) and no noise,
locks up firm and slips none.
