Automatic Transmissions

Automatic transmissions have a complex design.  They use electronics and hydraulics to operate a series of drums, gears, and clutches. In other words, electronics play a big part in your transmission’s operation.  They also utilize an internal computer to control transmission operations.

However, what may have previously been diagnosed as an internal transmission failure may be a wiring, sensor, solenoid problem, and/or computer failure. Therefore, we use state-of-the-art diagnostic tools.  We can detect your automatic transmission issues to determine the appropriate next steps.

Here is a video on how automatic transmissions work.

Standard Transmissions

Standard transmissions are not as complex as automatic transmissions.  However, they need a complete analysis to determine any problems. Often we see standard transmissions with a worn or broken clutch or clutch hydraulic problems. The clutch is designed to stop transmission movement so that the driver can shift gears. Proper diagnostics may prevent you from paying for unnecessary auto repairs and services.

We provide expert standard transmission diagnosis free of charge. Whether you drive an automatic, standard, domestic, or foreign vehicle, Sonny’s Automotive has the right technicians who can properly diagnose and repair repair your transmission.
