Just yesterday the check engine light has turned on for the first time. This car has 112000 miles and runs great. I went to AutoZone and the guy there was very helpful and he connected an auto scanner and told me that there is a mulfuction associated with TCC (something like Torque converter ... ).

Any ideas or hints what this thing is? And, how much it may cost to get this repaird? Or any thing else that someone here could suggest for me to try in order to get this terrifying check engine light fixed up?

Regards.
