Tips That Will Help Prolong the Life of Your Transmission

• Have your vehicle checked twice a year for transmission leaks.
• Inspect the transmission fluid after running your engine hot.
• Make sure you keep your engine in good condition and good working order.
• Make more frequent transmission fluid changes if you drive in high-stress conditions.
• If you think there is a problem with your transmission, have it checked out right away.
• Have the transmission fluid checked on a regular basis.
• Never play transmission mechanic, it is best if you have your transmission checked by a professional.

You depend so much on your vehicles every day. Whether it’s the family SUV or a work truck, it can be frustrating when you experience transmission problems. Sometimes, standard transmission maintenance is all you need to get back on the road. Other times, the damage may be more severe and major transmission repairs—or even a full transmission rebuild—may be required.

When it comes to transmission repairs, you want to put your trust in a specialist who understands the complexities of a transmission and the entire drivetrain system. A regular mechanic may not be as knowledgeable about transmissions, so you’ll want an expert like Ralph’s Transmission to help you. Transmissions are our business.

A Commitment to Quality

Ralph’s Transmission opened in 1969 and has become a Central Valley tradition. It has always been a family-owned business known for quality service with a distinctively personal touch. When you take your car, truck or SUVs to Ralph’s, you know it’s always in the best of hands. When local transmission industry veterans, Mario & Maria Jauregui, purchased this Modesto shop, they were drawn to its strong local roots. “We’ve always believed in family-run businesses,” Mario says. “The heritage of Ralph’s was strong and we wanted to continue growing on the shop’s longheld commitment to quality.”

Looking Forward

At Ralph’s Transmission, we are committed to more than just continuing a local legacy of excellent customer service. We are focused on the future. The transmission industry has changed a lot since 1969, so we have incorporated new technology and cutting-edge techniques to bring Ralph’s Transmission into the 21st Century. This has included the installation of heavy-duty lifts to handle large work trucks and hiring technicians with specific transmission experience to provide specialized services. One of our boldest moves is offering an industry-leading 3 Year, 100,000 Mile Warranty on all transmission rebuilds performed at Ralph’s Transmission shop. We stand behind our quality and you can rest assured that your rebuilt transmission will stand the test of time.
