The TCC solonoid is the electronic device that causes the torque converter to lock-up and un lock when you are the drive over about 45.

Drive about 50, touch the brake lightly, if it is working the torgue converter will disengage and you will hear and engine rpm increase. After you hear the increase, it will shift back into lock up. The rpm change is about 250.

If the torgue converter will not unlock then it is a major stall condition as it will be a direct connection to the engine without a torgue converter. Good luck

Suggested Repair

Road-test the TCC: drive about 50 mph and lightly touch the brake. If it is working, the torque converter should unlock, engine RPM should rise about 250, then lock up again. If it will not unlock, the direct coupling can cause a major stall.

Conversation Summary

The owner of a 1993 Toyota Corolla 1.8 says the car stalls for a couple of seconds when coming to a complete stop after replacing the fuel filter, coolant temperature sensor, and tune-up parts. They asked where the TCC solenoid is and how to tell if it works. The expert explained that it locks and unlocks the torque converter above about 45 mph and described a brake-tap road test looking for roughly a 250 RPM change; failure to unlock can cause a stall.
