Correct me if I'm wrong on this TC issue I have.

Shouldn't the TC unlock when you take your foot off the accelerator pedal? While at a steady speed above 48 mph and TC locked, when I let the engine go to idle (or try to) my TC is staying locked unless I tap on the brakes fairly hard. I do have a modified VB and 3disc converter but I don't think that should matter, right?

The torque convertor should unlock and the RPM drop.  The TC lock up switch is put in to keep the convertor locked.        I believe the APPs going to idle circuit sends a signal to unlock the TC.
