Transmission Repair & Service
Your transmission is responsible for shifting gears and transferring power from the engine to the wheels. When it’s not functioning properly, you’ll feel it—hesitation, slipping, hard shifts, or even no movement at all.
Our team provides complete transmission service in Spokane, including everything from routine maintenance to rebuilds and replacements.
Transmission Diagnostics
Not sure what’s going on with your transmission? We use advanced transmission diagnostic equipment to identify internal issues, whether they’re mechanical, electrical, or fluid-related.
Symptoms we troubleshoot:
-
Slipping gears
-
Delayed engagement
-
Rough or jerky shifts
-
Burning smells
-
Leaks under your car
-
Dashboard transmission warning lights
Once we identify the issue, we’ll explain it clearly and help you make the right call—whether it’s a repair, rebuild, or fluid service.
Transmission Fluid Service
Low, dirty, or burnt transmission fluid is a major cause of premature transmission wear. We offer fluid flushes and exchanges for both automatic and manual transmissions to keep things running smoothly.
Benefits of routine fluid service:
-
Smoother gear changes
-
Improved fuel economy
-
Longer transmission life
-
Reduced risk of overheating
We recommend checking your transmission fluid every 30,000 to 60,000 miles, or sooner if you drive in heavy traffic or haul loads frequently.

If your transmission is damaged, we offer a full range of repair services including:
-
Clutch replacement (manual transmission)
-
Solenoid and sensor replacements
-
Valve body repairs

Torque converter replacements

We work on all major makes and models, including front-wheel, rear-wheel, and all-wheel drive systems.

Frequently Asked Questions
How much does engine repair cost?
It depends on the issue. Minor repairs like sensors or gaskets can be a few hundred dollars, while a full engine swap or rebuild can cost more. We’ll always provide an upfront quote before starting any work.
Do I really need a transmission flush?
If your transmission fluid is old or dirty, yes. Routine fluid changes help your transmission last longer and shift better—especially in stop-and-go traffic or mountainous terrain.
How do I know if I need a new engine or transmission?
Our engine diagnostics and transmission diagnostic process will reveal whether a repair, rebuild, or replacement is the best option. We’ll explain everything clearly so you can make the right choice.
How long does engine or transmission repair take?
Simple repairs can often be done same-day. Swaps or rebuilds may take several days depending on parts availability and the complexity of the job. We’ll keep you updated throughout the process.

Absolutely. We service all makes and models—foreign, domestic, gas, hybrid, and diesel.
