TCI3200 Problems!!
While cruising if I let completely off the gas, the TC will not unlock. Instead the car has major surge back and forward. I have to tap the brakes to get the converter to unlock. When I release the brake, the TC locks back up and the surging continues! What is going on here? Do I need a new converter? Is there something wrong inside the tranny? This converter keeps locking up when it shouldnt!

How do you know it isn't doing what's programmed?
Or, if it hasn't ever been programmed, that's the likely
trouble. Lot of mods on there, your deceleration fuel
cutoff is a likely bad boy but it may also just be screwy
low-MAP, low-RPM mixture supplying the jerk and the
throttle follower supplying the air. But you can tell the
PCM to release at whatever MPH/TPS you like. The
stock TCC settings don't play so well some of the time.

The torque converter will only lock up and unlock based on commands from the PCM. Since it does lockup properly and then unlock when you tap your brakes, it sounds like a programming issue.
