Put in a 3000 stall in my truck over the weekend. Tried the 90/100 settings in the PWM tables, helped it lock nicely but now whenever I get off the throttle it unlocks. Locks up about 3 seconds after getting back on the throttle.

Long shot but you wrote 90/100 . Do you mean 100 for the max table and 90 in the min. in the auto tcc table? Reason I ask because if you had them backwards like 90max and 100 min maybe that can cause something. I can load your stock tune wont let me load the new street tune.

Apparently, this garbage is normal.. It will not listen to any of your input on the 2nd gear lock up either.. unless its via scanner... Search TCC lock.. or tcc unlock.. you're bound to find a similar post..

scan for misfires
If you have a bunch of misfires the tcc will unlock

no misfires. this is apparantly a product of GM tuning and the T42 transmission controller that will ALWAYS unlock the converter when you let off the gas.
