Our Five-Step Transmission Diagnostic Process
-
Customer Consultation
We begin by listening to your symptoms and vehicle history. This helps us narrow down potential causes. -
Road Test & Visual Inspection
If safe to drive, we evaluate shift behavior, performance, and noises during a controlled test. -
Advanced Transmission Diagnostic Testing
Using manufacturer-level scan tools, we read transmission fault codes, monitor live data, and evaluate internal pressure, temperature, and shift timing. -
Inspection of Transmission Fluid
We check the level, color, and smell of your transmission fluid to assess wear and contamination. -
Detailed Results & Estimate
You receive a complete digital inspection with prioritized recommendations, photos, and an upfront estimate—no surprises.
The Importance of Transmission Fluid Maintenance
Clean transmission fluid is critical for reducing friction, cooling internal components, and ensuring consistent hydraulic pressure. Over time, fluid breaks down and accumulates debris, leading to:
-
Hard or delayed shifting
-
Increased transmission temperature
-
Worn clutches and seals
-
Poor fuel economy
-
Total transmission failure if neglected too long
We recommend fluid service every 30,000–60,000 miles depending on vehicle type and driving conditions. Ask us about your specific make and model—we’ll check the fluid condition and advise you honestly.
Transmission Fluid Service Includes:
-
Draining or flushing old fluid
-
Replacing the transmission filter and pan gasket (if applicable)
-
Refilling with fresh, manufacturer-approved fluid
-
Reprogramming adaptive shift memory if needed
-
Resetting transmission-related service reminders
This routine maintenance extends transmission life and helps prevent costly repairs.

For manual vehicles, we also offer:
-
Clutch replacement and hydraulic component service
-
Flywheel resurfacing or replacement
-
Shift linkage adjustments
-
Gear synchronizer inspections and repairs

Manual or automatic, your vehicle deserves expert care—and we’ve got the tools and experience to deliver it.
Frequently Asked Questions (FAQs) About Transmission Service & Repair
Q: How often should I change my transmission fluid?
A: Most vehicles benefit from fluid replacement every 30,000 to 60,000 miles. Some newer transmissions are labeled “lifetime fill,” but even those may need service depending on usage. We recommend checking fluid condition during every major service visit.
Q: Is a transmission flush safe?
A: When done correctly using the right equipment and fluid, a transmission flush is safe and effective. We follow manufacturer guidelines to avoid dislodging harmful debris.
Q: What’s the difference between a fluid change and a flush?
A: A fluid change replaces only the fluid in the pan (about 40–60% of the total), while a flush replaces nearly all of the fluid throughout the transmission. We’ll help you decide which service suits your vehicle’s needs.
Q: Can I drive with a slipping transmission?
A: We don’t recommend it. Slipping puts stress on internal components and can lead to complete failure. It’s best to have it diagnosed right away.
Q: What causes transmission failure?
A: Common causes include old or low fluid, worn internal parts, overheating, and neglecting service intervals. Early detection and regular maintenance are your best defenses.
Q: How much does transmission repair cost?
A: Pricing varies by issue and vehicle type. A fluid service starts around $150, while major repairs or rebuilds can range from $1,500 to $3,500 or more. We’ll always provide an honest, upfront estimate before starting work.
