    May be you can take that TCC and goto a Transimisdion shop to see if they have similar one .

    TCC is the TORque CONverter CLutch...it is a clutch..built within the torque converter..also known as "torque converter lock-up"....its operation "freezes" the torque converter ..and applies ONLY once the car has gained sufficient speed. It is NOT involved in making the car go from a standstill.
    THe TCC solenoid valve controls the TOrque Converted CLutch...but operational or damaged, it has no effect on making the car go from a standstill....only the actual torque converter (hydraulic) will make the car go from a standstill and the car can go on the road at normal speed without the TCC being applied....the engine would simply run faster due to torque converter slip.
    IF the car refuses to go, the forward clutch either does not apply or is damaged..or some other transmission mechanical component has been damaged from abuse.

    What symptoms might one expect from a TCC solenoid being stuck open at all times? If the torque converter is constantly engaged, would the vehicle be able to overcome inertia? Would the computer be too confused to continue the program with a torque converter being engaged at 5 mph and 750 RPMs?

    If a torque converter is stuck engaged you would have a hard time stopping the car with all your might pressing the brake. Again, it is likely not a solenoid or anything externally replaceable without removal of the transmission.

    So if the TCC solenoid is stuck open, could that loss of pressure prevent the shift solenoids from working properly?
