The malfunction indicator light (MIL) can be a great tool if you utilize it SOON after it illuminates. It comes on when your vehicles powertrain control module (PCM) senses any kind of problem, electrical or mechanical, most times before you can feel anything out of the ordinary. So if that MIL is on, it would be most beneficial to you to call the Pros at Quality Transmission Service and have the problem properly diagnosed with our state of the art computerized equipment. Services are available for all foreign and domestic front, rear, four-wheel & AWD drive vehicles. Commercial fleet accounts are also welcome.
