Automatic Transmissions


What You Need to Know

Automatic transmissions are complex.  They use electronics and hydraulics to operate a series of drums, gears, and clutches. They also utilize an internal computer to control transmission operations.

The Importance of Diagnostic Tools

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


What You Need to Know

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 worn or broken clutch or clutch hydraulic problems. The clutch is designed to stop transmission movement so that the driver can shift gears. We will diagnose your standard transmission to determine how much work might be needed.

Free Transmission Analysis

We provide expert standard transmission diagnosis free of charge. Whatever type of vehicle you drive, Sonny’s Automotive has expert technicians to properly diagnose and repair your transmission.

Here is a video on how standard transmission works.

Commercial Vehicle Exclusion

Commercial vehicles are excluded from Sonny’s Transmission Warranty Program.  (We can give you guidance on where to take your commercial vehicle for any necessary repairs.)
