Our Transmission Repair Services

Transmission Diagnostics and Evaluation

We perform comprehensive transmission system diagnostics to identify issues such as slipping gears, delayed engagement, and fluid leaks. Using advanced scanning and diagnostic equipment, our technicians assess the entire transmission system to detect both visible and hidden problems. This thorough evaluation helps prevent misdiagnosis and unnecessary repairs.

Transmission Fluid Replacement and Flush

Replacing and flushing transmission fluid is essential to maintain system health. Over time, transmission fluid becomes contaminated with dirt, metal particles, and debris that can impair performance. Our fluid replacement service removes old fluid and contaminants, then replenishes your system with high-quality fluid formulated for diesel transmissions. 

Clutch Repair and Replacement

For manual transmissions, clutch performance is vital to smooth and reliable operation. We inspect clutch assemblies, including pressure plates, discs, and release bearings, to identify wear or damage. Our repair or replacement services restore proper clutch engagement, preventing slippage and ensuring optimal power transfer from the engine to the transmission. 

Transmission Rebuilds and Overhauls

When minor repairs aren’t enough, our skilled technicians undertake full transmission rebuilds. This process involves disassembling the transmission, thoroughly cleaning all components, and replacing worn or damaged parts such as gears, seals, and bearings. A rebuild restores your diesel truck’s transmission to near-new condition, improving reliability and performance.

Torque Converter Repair and Replacement

The torque converter is a critical component that transfers engine power to the transmission fluidly and efficiently. Faulty torque converters can cause poor acceleration, overheating, and transmission damage. We diagnose torque converter problems using specialized equipment and either repair or replace the unit as needed. Regular inspection of this component helps avoid unexpected breakdowns.

Transmission Cooling System Service

Proper cooling prevents transmission overheating, a frequent issue in heavy-use diesel trucks. We inspect the transmission cooling system, including the radiator, cooler lines, and pumps, to detect leaks, blockages, or malfunctions. Repairing or replacing faulty components helps maintain optimal transmission temperature, which is crucial for preventing thermal damage.

Benefits of Professional Transmission Repair Services

Enhanced Vehicle Performance

Professional transmission repair ensures smooth gear shifts and optimal power delivery, significantly improving your diesel truck’s overall performance. This precision service reduces engine strain and helps maintain consistent acceleration and handling, which is especially important for heavy-duty trucks operating in demanding environments.

Increased Safety on the Road

A properly functioning transmission prevents unexpected gear failures or sudden stalls that could lead to dangerous situations. Professional repairs restore reliable transmission operation, helping drivers maintain control and avoid accidents, particularly on busy highways and industrial routes. This increased reliability directly supports driver confidence and vehicle safety compliance.

Cost Efficiency Over Time

Early and accurate transmission repairs prevent minor issues from escalating into major failures. Addressing problems promptly reduces the risk of expensive overhauls or replacements, saving truck owners substantial repair costs in the long run. This proactive approach also helps maintain vehicle resale value.

Improved Fuel Economy

A malfunctioning transmission can cause inefficient power transfer, leading to increased fuel consumption. Expert repairs restore proper function, optimizing fuel efficiency—a critical benefit for commercial diesel truck operators managing operational costs. Improved fuel economy also reduces the environmental impact of your fleet.

Reduced Vehicle Downtime

Timely transmission service minimizes breakdowns and reduces repair times, enabling diesel trucks to return to the road quickly. This is crucial for maintaining schedules and productivity, particularly for fleets operating in fast-paced logistics sectors. Efficient repairs also help prevent cascading mechanical failures.

Accurate Diagnostics and Tailored Repairs

Professional technicians utilize advanced diagnostic tools to pinpoint exact transmission issues. This ensures repairs are precisely targeted, preventing unnecessary part replacements and ensuring customized solutions that fit your specific vehicle’s needs. This thorough diagnostic process enhances the reliability of repairs and customer satisfaction.
