this code is set when the pcm detects the tranmsission is slipping in a gear. this can be caused by low fluid, or worn clutch packs.
the best thing to do would be to clear the code, have the transmission fluid servise with a new filter and see if the code returns. I have seen the filter crack and suck air in and set theis code off.
