Common signs your transmission needs service:
-
Difficulty shifting gears or delayed engagement
-
Grinding, shaking, or clunking while driving

Transmission slipping between gears

Leaking red or brown fluid underneath your car

Burning smell or unusual noise from under the hood

Automatic and Manual Transmission Specialists
Automatic and manual transmissions require very different types of care — and we handle both with precision.
Automatic transmissions
We use advanced diagnostic software to identify sensor errors, pressure issues, and shifting irregularities. Our team can replace or rebuild key components to ensure seamless gear changes and reliable performance.
Manual transmissions
If you drive a stick shift, we offer expert clutch repair, hydraulic system service, and transmission rebuilds to restore that smooth shifting feel. Whether your clutch pedal feels spongy or gears grind when shifting, we’ll get it back in perfect condition.
Transmission Maintenance for Long-Term Performance
Like your engine, your transmission needs regular maintenance to stay reliable. Fresh fluid keeps internal parts lubricated and prevents overheating — one of the most common causes of transmission failure.
Our maintenance services include:
-
Transmission fluid and filter replacement
-
Cooling system and line inspections
-
Transmission flush and reseal
-
Preventive checkups during oil changes
Many drivers ask, “How often should I service my transmission?” The answer depends on your vehicle type and driving conditions, but a good rule is every 30,000 to 60,000 miles. Our technicians can create a maintenance plan tailored to your specific vehicle.
