4l80e PI triple disc stall

Selling my Precision Industries triple disc torque converter and TCI flex plate. Converter flashed to 2800ish RPM behind my TVS 5.3.
Converter was removed during 4l85e rebuild due to whine in first and replace with lower stall speed for towing. Turned out the whine was due to 1st gear 5 pinion plants and the nature of many of the 4l85e's.
$600 Shipped.

It's a straight cut gear set that causes the whine. Some builders use them since they are considered "heavy duty".

The helical gear set doesn't whine.
