TCC Lock in Second ? 4L80 w/ CircleD triple disc clutch. Stalls around 3000 hot.
Any benefit to locking toward the top of Second gear ?
.
.
Second question: What is best strategy to soften part throttle TCC lock in 3rd and 4th gear? Working in the HPTuners 15231 TCC DC Minimum table;
Should I "ONLY" Lower the Duty Cycle vs Line pressure in the bottom most cells, ie 0 through 24 ish line pressure ? Percentage reduction, or should I just "Minus 10" from a few columns ?
Would it be smart to leave the low temperature and high temp rows alone, so I don't slip more if I get it hot ?
.....Thanks for any tips.

Triple disc is gonna be rather abrupt , You could pay with they rate of apply but I would worry of burning the clutch, Ask the manufacturer what he thinks (converter).
Locking at the top of gears may or may not be beneficial , In my own car locking above 3800 rpm gained 30ftlb torque on the dyno. But that would vary by converter . rear, engine, power bands.
As for the rest not being a tuner I will leave that to someone else.
