Torque Converter Clutch circuit malfunction
What does it exactly mean?

anyone?

There is a fault in the lock-up control system which may be caused by a faulty solenoid. My cousin had this code awhile back, and if memory serves me correct, we had to change the lock-up(?) solenoid. Once replaced the code never returned. BTW - this was done on a '00 TL-P. Hope this helps.

I would have to agree with Lawaia. Sounds like a selonoid problem (but it could be something else)

how much would it cost if that was the case, and what causes this?

honestly ??? PM fla-tls hes owns a tranny shop and may be able to tell you more
