What does TC light mean

What is your question?

I had a display panel light to come on and it read TC with a line across the letters. My car was in motion after I fueled and the engine was running but I couldn't accelerate rate. I could mash the pedal but the car barely moved. I shut the engine down and sat in car for a few minutes. Restarted and it ran normally and light went off.

How long has your 2004 Cadillac Escalade had this problem?

Just a few minutes
