Transmission Services We Provide

Transmission Diagnostics

We scan for fault codes, perform pressure testing, analyze fluid condition, and road test the vehicle to pinpoint the exact cause of any transmission problem before recommending repairs.

Transmission Fluid Service

Regular fluid changes are the most effective way to extend transmission life. We drain the old fluid, replace the filter where accessible, inspect the pan for debris, and refill with the correct fluid type for your vehicle.

Transmission Repair

Many transmission problems can be resolved without full replacement. We repair solenoids, sensors, valve bodies, seals, and internal components to restore proper function at a fraction of the replacement cost.

Transmission Replacement

When a transmission is beyond repair, we install a remanufactured or rebuilt unit. We handle complete removal, installation, and post-repair road testing.

Manual Transmission and Clutch Service

We service manual transmissions and clutch systems from minor adjustments to complete clutch replacement including flywheel resurfacing, hydraulic system service, and linkage adjustment.

Torque Converter Service

A failing torque converter causes shuddering, slipping, and overheating. We diagnose torque converter issues and replace when necessary as part of a complete transmission service.

Differential and Drivetrain Service

Complete drivetrain service including differential fluid changes, axle seal replacement, CV axle replacement, U-joint replacement, and transfer case service for 4WD and AWD vehicles.

Transmission Leak Repair

Transmission fluid leaks lead to low fluid levels and serious internal damage. We locate the source of any leak and repair seals, gaskets, lines, or pan as needed.

Frequently Asked Questions

How often should transmission fluid be changed?

Most automatic transmissions need fluid changed every 30,000 to 60,000 miles depending on the manufacturer's recommendation and driving conditions. Vehicles used for towing, heavy traffic driving, or in extreme heat need more frequent service. Manual transmissions typically require fluid changes every 30,000 to 45,000 miles. Check your owner's manual or ask us and we will look it up for your specific vehicle.

Can a slipping transmission be repaired without full replacement?

Often yes. Slipping is frequently caused by low fluid, a worn solenoid, a faulty valve body, or a failing torque converter, all of which can be repaired at a fraction of the cost of a full replacement. A proper diagnosis is essential before assuming the worst. We diagnose first and give you honest options.

What does dark or burnt-smelling transmission fluid mean?

Fresh transmission fluid is typically bright red or pink. Dark brown or black fluid with a burnt odor means the fluid has broken down and is no longer protecting internal components. It also often indicates the transmission has been running hot, which can cause significant internal wear. Bring it in as soon as possible.

How long does a transmission repair take?

A fluid service takes about an hour. Diagnostic work typically takes one to two hours. Repairs involving internal components or a full replacement can take one to three days depending on parts availability and the extent of the work. We give you a time estimate before starting and keep you informed throughout.

Do you work on both automatic and manual transmissions?

Yes. We service both automatic and manual transmissions on foreign and domestic vehicles of all makes and models.

Is it worth repairing a high-mileage transmission?

It depends on the overall condition of the vehicle and the cost of the repair relative to the vehicle's value. We give you an honest assessment. If the repair cost makes sense for the vehicle, we will tell you. If it does not, we will tell you that too.
