transmisssion

There can be many issues, and a warning light is just to let you know that a fault has been detected by one or more of the computers, and the diagnostic data needs to be retrieved form all the computers in your car, then a diagnostic approach can be formed. This type of work is best left to a trained mechanic, http://repairpal.com/new-york-auto-repair

You see a gear with ! in the center meaning that your transmission program detected a failure. When it doesn't pull it is in 'safe' mode and usually simply turning the engine off and starting the car again fixes that. You should however get it checked if it happens again since there is most likely an issue with your transmission.

its the light sensor telling you to turn on your lights
