This means you have aload of miles and you have to go to the mechanic or you will fail a transmission test. Sometimes it stays even when a mechanic tries fixing it good luck.

Good news scenario
On Kias and Volkswagons (and maybe others) this light comes on if you don't screw the gas cap on tight enough. Try it, it saves a pile of bucks for having the mechanics check and replace the "thermin wire" or "muffler bearings" (and tighten the gas cap)
