What is the first thing I need to think about and research? Or what may be causing the problem?
My experience is more w/the TH350C, but the FIRST thing I would check is to see if the TCC solenoid ground supply circuit was shorted between the PCM and the solenoid, or if the solenoid has failed internally. Then I'd check for the solenoid fluid exhaust passage being blocked off w/a piece of gasket or sealer, etc. You'll have to drain the pan and remove it.

You should check the TCC apply valve for being stuck in the "on" position- you did mention a sticky valve in the valve body...

The only other non TC thing I can come up w/is the torque converter clutch valve being stuck.

If this all gets you nowhere, then I'd be suspecting the TC.
