The lighting - instrumentation included with the trans components - automatic is a warning system for motorists. Its job is to signal that something is malfunctioning in the transmission of the Cadillac STS. Possible problems might be that it is running either too hot or cold, or it might be slipping out of gear.
If the transmission of your Cadillac STS isn't running smoothly, you will notice difficulty when shifting gears, a loss of acceleration, and total transmission failure. Without the warnings issued by the lighting and sensor, you may not notice these problems until it is too late. Find replacement parts at StockWiseAuto.com today.
