Default TT3000 is locking and locking on 1 to 2 and 3 to 4 upshift...

I hope you F-body guys can help me out as well... The converter I have is the Yank Truck Thruster 3000.

Under normal driving pulling away from a light or a stop sign the converter will lock as soon as the up shift is applied then a second later the converter will unlock then do the same thing on the 3 to 4 upshift. It feels like a bog and its kind of annoying. How can I get rid of this? I have access to Ls1 edit if neccessary.

Thanks,
Sean

Easiest way is to raise the lock-up speed in Edit at low tps.

Are you sure it is locking? In an F-body, the factory does not use lock-up in second gear.

Try unchecking the "lock converter through shifts"
as a starting point. You may have to raise the whole
TCC lock speed vs TPS curve, to keep it from being
a pest. I had the same kind of deal with my TCI3000.
It's just not noticeable with the stock stall speed &
tightness but feels real jerky with a looser converter.
