Our Auto Repair Service Specialties

  • Auto A/C Repair & Service

    Auto A/C Repair & Service

    Your auto A/C system is complex and likely to experience at least some type of issue during your vehicle’s lifetime—whether your air conditioning unit just needs to be recharged or you have a faulty condenser or computer issue, which are both very common auto A/C problems. If your car air conditioning isn’t keeping you cool the way it should, stop by Protrans Automotive for an A/C diagnostic and any necessary air conditioning repairs. Our mechanics won’t tolerate a bunch of hot air coming from your vehicle.



  • Brake Repair & Service

    Brake Repair & Service

    Your car’s brakes must apply thousands of cumulative pounds of force to stop reliably during a single trip around town. So, it’s no wonder brakes wear out over time and require service. Staying on top of brake maintenance items, such as brake pad replacement, and promptly addressing brake problems, like noises and poor response time, is essential to protect yourself, your passengers, and other drivers on the road. Protrans Automotive offers complete brake repair and service to ensure your brakes perform optimally.


  • Check Engine Light

    Check Engine Light

    If your check engine light is on, Protrans Automotive has the equipment and skill to properly diagnose the issue and handle any necessary auto repairs. A thorough check engine light diagnostic is more than just connecting a scanner to your vehicle and pulling trouble codes, as a code does not always indicate exactly what is wrong with your car. In the Riverside area, our mechanics are known for their auto diagnostic capabilities and figuring out precisely what’s wrong with the vehicles we service.


  • Suspension Repair & Service

    Suspension Repair & Service

    Your vehicle’s suspension system serves two main purposes: handling and comfort. The shocks and struts also have a significant impact on your vehicle’s safety, as worn shocks and struts can affect how your wheels connect with the road and accelerate wear and tear on your tires. Protrans Automotive offers comprehensive suspension repair and service, including struts, shocks, tires, and tie rods, so you’re able to stop, turn, and control your car with ease. If you’re feeling every bump in the road, give us a call.


  • Transmission Rebuilding, Repair & Service

    Transmission Rebuilding, Repair & Service

    If you think your vehicle has a transmission problem, you may be feeling nervous, as transmissions have a bad reputation for being expensive to fix. But we advise you not to wait. In most cases, the problem will only become worse, and you’ll be facing more extensive transmission repairs. Protrans Automotive started out as a transmission rebuilding shop, and we continue to be Riverside’s transmission experts. We can determine exactly what’s causing the symptoms you’re experience and handle all necessary transmission repairs.


  • Wheel Alignments

    Wheel Alignments

    Wheel alignments keep your vehicle running safely and efficiently by reducing tire wear, improving gas mileage, and promoting safer driving conditions. Left untreated, wheel alignment problems can turn into steering and suspension issues because driving with wheels out of alignment not only puts stress on your tires but also on suspension system components. We have state-of-the-art wheel alignment equipment at Protrans Automotive, and we’ll make sure any wheel alignment issues you’re experiencing are totally straightened out.
