Today’s vehicles are primarily computer-controlled and utilize sophisticated technology to operate properly. The use of this technology plays a significant part in the diagnosis of your vehicle’s performance. When your vehicle is illuminating the dreaded “Check Engine” light or not running properly, Computer Diagnostics are often needed to determine what part is malfunctioning.

When a warning light is illuminated, this means the on-board computer system in your vehicle has detected a problem or service need with one or more of the many different systems it monitors and controls, such as your engine or transmission. Therefore, we recommend our Computer Diagnostics service to provide you with an accurate assessment of your vehicle’s condition. Mr. Transmission Computer Diagnostics services utilize state-of-the-art equipment, which is connected to your vehicle to view any computer trouble codes.
