Automatic Transmission

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

What may have previously been diagnosed as an internal transmission failure may be the wiring, sensor, solenoid problems, and/or computer failure. We use state-of-the-art diagnostic tools to understand your automatic transmission issues.

Standard Transmission

Standard transmissions are not as complex as automatic transmissions but also 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.

Sonny’s provides expert transmission diagnosis free of charge. Whether you drive an automatic, standard, domestic or foreign vehicle, Sonny’s Automotive has an expert technician who can meet your needs.


Commercial vehicles are excluded from this transmission warranty program so don’t worry, we can give you guidance on where to take that vehicle!
