What might cause my 2010 Acura TSX check transmission light to come on?

The 2010 Acura TSX check transmission light may come on due to low transmission fluid or an issue with the transmission temperature sensor. One of the first things You should do if Your transmission warning light comes on is to check the transmission fluid. If Your fluid level is good, a problem with a transmission temperature sender may be the culprit. A light that flickers or comes on only when hitting bumps on the roadway may indicate a loose transmission wiring connection or a bare wire. Other problems, such as harsh or erratic shifting, not shifting from first gear automatically or transmission fluid that appears dark or smells burnt are problems that do not require a transmission warning light to tell You that there is a problem.
