Automatic Transmission Repair

Automatic transmissions represent the most common drivetrain configuration, and our shop has extensive experience servicing every major manufacturer's design. If you're experiencing delayed shifts, slipping gears, or fluid leaks, we perform thorough inspections to identify the root cause. Our repair process includes precision adjustments, component replacement, and comprehensive testing to restore smooth operation.

Automatically Shifted Manual Transmission Service

Dual-clutch and automated manual transmissions combine the efficiency of manual gearboxes with automatic convenience, but they require specific diagnostic equipment and expertise. We service these sophisticated systems found in many European and performance vehicles, addressing concerns like rough shifting, clutch wear, and electronic control issues. Our detailed approach ensures these specialized transmissions receive the precise calibration they need.

Clutch Repair

A failing clutch affects your ability to shift gears and can cause significant drivability problems if left unaddressed. We handle clutch replacements for manual transmission vehicles, including pressure plate, disc, and release bearing installation. Our technicians also inspect flywheels for damage and resurface or replace them as needed to ensure optimal clutch engagement and longevity.

CVT Transmission Service

Continuously variable transmissions deliver excellent fuel economy but require specific maintenance protocols to prevent premature failure. We perform CVT fluid exchanges using manufacturer-specified fluids, inspect belt and pulley wear, and address common issues like shuddering or loss of acceleration. Regular CVT maintenance at our shop extends transmission life and maintains the smooth, seamless power delivery these systems are designed to provide.

Manual Transmission Repair

Manual transmissions offer driving engagement and mechanical simplicity, but they still require skilled repair when synchronizers wear or bearings fail. We rebuild manual gearboxes, replace worn components, and address shifting difficulties that compromise your driving experience. Our attention to detail during reassembly ensures proper gear mesh and smooth operation across all ratios.

Road Ripper Transmission

Performance and heavy-duty applications demand transmissions built to withstand increased torque and harsh operating conditions. We service and repair reinforced transmissions designed for racing, towing, and commercial use. Our experienced staff understands the unique requirements of these robust systems and can recommend upgrades or modifications to improve durability and performance for demanding applications.

Transmission Differential

The differential works in tandem with your transmission to distribute power to the wheels while allowing them to rotate at different speeds during turns. We diagnose and repair differential issues including gear wear, bearing failure, and seal leaks. Our comprehensive service includes fluid changes with appropriate lubricants, gear pattern inspection, and backlash adjustment to eliminate noise and ensure reliable power transfer to your wheels.
