General Auto Repair services in kearny mesa, san diego


Ruffner Transmission is a full-service transmission repair shop in San Diego, but we service more than just transmissions. Modern cars are complex machines with several interconnecting components, and we offer a full spectrum of repairs on domestic and foreign vehicles to keep your car running in top condition for years to come.

car Suspension repair

The main purpose of a car’s suspension system is to provide a smooth ride, but a failing suspension system will do more than just create a bumpy ride. It can hinder your ability to control your car and will wear out your tires much faster than normal. 

Here’s how to tell you might need a suspension repair:

  • You can feel every bump in the road.

  • Your car drifts or pulls when you turn.

  • You have difficulty steering.

  • The front end lurches forward or “nose dives” when you brake firmly.

  • One corner of your car sits lower than the others.

  • The tread on your tires is wearing down unevenly.

To catch suspension problems before they become safety hazards, Ruffner Transmission will check the wheel alignment, shocks, springs, ball joints, and control arms to diagnose the problem.

car Brake repair

Brakes play a vital role when it comes to safety for you, your passengers, and everyone else on the road. It’s important to schedule regular maintenance and immediate repairs when necessary. Ignoring even simple fixes like new pads can be costly down the road. 

Keep an eye out for these signs that it might be time for a brake system service or repair:

  • Your car pulls to one side when you apply the brakes.

  • The brake pedal feels “spongy” or hard to press down.

  • Your steering wheel, brake pedal or the entire car shakes or vibrates when you apply the brakes.

  • The brake warning light on your dashboard lights up.

If you notice any of the above signs or if your brakes start squealing or grinding, bring it to Ruffner Transmission so we can check the brake pads, rotors and caliper assembly to pinpoint the cause of the problem.

car Tune-ups

Regular maintenance for your vehicle means more than oil changes and brake pad replacement. Regular tune-ups can spot problems long before they become expensive repairs. 

It’s probably time to schedule a tune-up if you notice any of these signs:  

  • The engine shakes or shudders when idling.

  • Acceleration is sluggish.

  • The engine frequently stalls.

  • A strange odor is coming from the exhaust.

  • You notice a drop in fuel economy.

  • The check engine light is illuminated.

Our comprehensive tune-up checklist at Ruffner Transmission includes spark plugs, the fuel filter, fuel pump, fuel injectors, PCV valve, and adjustments in the engine timing and idle if necessary.

car Timing belt repair

The timing belt is a crucial engine component that rotates the camshaft and crankshaft in sync and ensures each cylinder fires at the right time. But even though it’s made out of high-quality rubber with nylon-reinforced cords inside, it won’t last forever. It will need to be replaced before it breaks entirely. Without a timing belt, the engine will not run at all.

Here are some symptoms of timing belt wear to watch for:

  • You hear a ticking, squeaking, or squealing noise coming from the engine.

  • The engine frequently misfires.

  • Motor oil is leaking from the timing belt cover.

  • Extra emissions are coming from the exhaust.

  • The engine won’t turn over at all, which means the belt is already broken.

If you notice any signs of wear or damage, bring your car to us at Ruffner Transmission. We’ll thoroughly inspect your timing belt, diagnose the problem, and replace it if necessary.

car Oil change

The standard schedule for regular oil changes is every 3 months or 3,000 miles, but if you’ve been driving more than usual or in harsher climates that cause your engine to work harder, you might need an oil change sooner than anticipated. If you don’t change your oil or let it get too low, the resulting friction can damage engine components or seize the engine entirely in a worst-case scenario. 

If you can’t remember when you had your last oil change, here are some signs that it’s time to schedule one:

  • Your engine runs louder than usual.

  • The oil level is low.

  • The oil is black & sludgy instead of transparent & honey brown.

  • The dashboard oil light illuminates.

  • During a regular oil change, Ruffner Transmission will also check for leaks & inspect all seals & gaskets to ensure your engine gets the oil it needs.
