Transmission Rebuilds & Replacements in Kearny Mesa, San Diego


Full-Service Transmission Repair

Your transmission is one of the most important and complicated components in your vehicle. Its job is to transmit the right amount of power from the engine to your wheels so you can drive at a given speed. In other words, if your transmission isn’t working properly, you’re not going anywhere fast. 

Ruffner Transmission is a full-service transmission repair shop in San Diego specializing in transmission rebuilds and replacements, fluid and filter replacements, and transmission diagnostics. We work on vehicles with manual, automatic, and four-wheel drive transmission, as well as continuously variable transmission (CVT) vehicles. With over 20 years of experience in transmission repairs, our technicians have the expertise to diagnose your vehicle’s problem quickly, fix it right the first time, and get you back on the road safely.

Transmission Rebuild

A transmission rebuild starts with the complete removal and disassembly of your transmission. From here, our expert technicians will carefully inspect all components to identify which parts need to be replaced and those that are still in good working shape. Upon completion, your transmission will be restored to its peak operating condition without having to replace every single part.

Transmission Replacement

If your car is leaking transmission fluid or refuses to shift into gear, you might need a complete transmission replacement. Unlike a transmission rebuild, a transmission replacement involves removing your old transmission and swapping it out with a refurbished or re-manufactured one. Replacing your transmission offers peace of mind that you won’t have to worry about problems in the future.

Fluid & Filter Replacement

Transmission fluid acts as a lubricant for all of the moving parts inside your transmission. Having your transmission fluid changed every 30,000 to 60,000 miles will extend the life of your transmission and could help you avoid a costly repair down the road. At Ruffner Transmission, our fluid and filter replacement services include draining and changing your transmission fluid, cleaning the oil pan, and replacing the filter.

Transmission Problems, Symptoms & Diagnosis 

Because your transmission has so many interconnected parts that are always moving, heating up, and interacting with other components, it’s normal for them to experience a degree of wear and tear over time. If you experience any of the following problems, we recommend bringing your vehicle into our San Diego transmission repair shop for a professional diagnosis and inspection as soon as possible:

  • A burnt smell coming from beneath the hood

  • Leaking transmission fluid

  • Difficulty moving your manual transmission gear shifter

  • Cloudy or thick transmission fluid on a dipstick test

  • Gear slipping, grinding, or jumping during acceleration

  • Vehicle shaking while driving at any speed
