Our Heavy-Duty Engine & Transmission Services

Engine Maintenance

Your engine is the heart of your vehicle — and preventive maintenance is the key to keeping it running strong. Regular oil changes, filter replacements, and tune-ups help maximize performance and extend engine life.Our expert technicians will inspect, service, and maintain your engine for peak performance and fuel efficiency.

Transmission Maintenance

Like your engine, your transmission requires regular care to perform properly. Our transmission maintenance service includes fluid checks, filter replacements, and inspections to detect early signs of wear — preventing costly breakdowns down the road.

Transmission Flush

A transmission flush removes old, contaminated fluid and replaces it with new fluid to protect internal components.If you notice slipping gears, grinding noises, delayed shifting, or surging, it’s time for a flush. We recommend this service every 30,000 miles or 2 years — or sooner if symptoms appear.

Timing Belt Replacement

The timing belt keeps your engine’s valves and pistons in perfect sync. A worn or broken belt can cause severe engine damage.We check your timing belt according to manufacturer recommendations and replace it before problems occur — ensuring reliable performance and avoiding expensive repairs.

Cylinder Head Repair & Reconditioning

The cylinder head seals the combustion chamber and regulates airflow in and out of the engine. Damage or warping can lead to compression loss, misfires, or poor performance.Our technicians specialize in cylinder head inspection, repair, and resurfacing, restoring your engine’s power and reliability.
