If your vehicle has over 100,000 miles, it’s important to prepare yourself for the possibility of transmission-related problems. Transmission failure is not guaranteed at this mileage — however, this stage of ownership is when routine inspections and preventative maintenance become especially important. Below, this transmission repair specialist in Villa Park, Illinois is going to highlight some of the most common failures in high-mileage cars.
Worn clutch packs and bands
Automatic transmissions use clutch packs and bands to engage and hold the correct gears. These parts depend on friction material and hydraulic pressure to run smoothly.
Constant heat exposure and repeated gear changes gradually wear down friction surfaces. As clutches wear, they lose their ability to hold gears securely when the vehicle is under load. Transmission slipping is usually the first (and perhaps the most noticeable) sign of clutch wear.
Valve body issues
The valve body can also impact smooth shifting. The valve body controls how transmission fluid flows through the transmission and uses clean, properly conditioned fluid to shift gears smoothly.
Transmission fluid breaks down and collects contaminants as it ages. Dirty fluid can restrict fluid passages and cause valves to stick. Valve body problems commonly result in hard shifts, delayed engagement or erratic shifting behavior. High-mileage vehicles that go long periods without regular transmission fluid service are very likely to develop these problems.
Electrical control failures
Modern automatic transmissions have many electronic sensors, modules and solenoids. These electronics control shift timing and overall performance.
Constant heat and vibration can damage sensitive electronics over time. Aging vehicles can also develop wiring problems due to corrosion or wear.
Electrical transmission failures generally trigger dashboard warning lights or cause the vehicle to enter limp mode. A professional transmission repair specialist in Villa Park, Illinois will use advanced diagnostic equipment to correctly identify and resolve these electronic problems.
Torque converter failure
The torque converter is another part that shows its age in high-mileage cars. It transfers engine power to the transmission while keeping the vehicle from stalling when stopped. It also contains a lock-up clutch to improve fuel efficiency at steady cruising speeds.
The lock-up clutch inside the torque converter can wear out over time. This clutch can slip instead of engaging firmly when it no longer holds properly. This can cause noticeable vibration at highway speeds. Drivers may also experience fluctuating or unstable RPMs while cruising.
Seal and gasket failure
Even though internal components get most of the attention, external sealing parts are just as important. Transmission seals and gaskets naturally deteriorate as vehicles age. Continuous exposure to heat and internal pressure causes these components to harden and crack.
Transmission fluid can leak from the system when seals fail. Low fluid levels reduce essential cooling and lubrication for internal components. Low transmission fluid levels can then lead to overheating and rough shifting.
Neglected maintenance-related failures
Some transmission wear is inevitable as mileage increases. Taking your vehicle to a professional transmission repair specialist in Villa Park, Illinois for routine service can considerably slow this process.
Fresh, clean transmission fluid protects internal components from excessive heat and friction. Old or contaminated fluid, on the other hand, increases the risk of internal damage. Regular inspections can increase the life of your transmission and early attention to minor problems can prevent sudden breakdowns.
