Our standards
At Clarity Auto Care, we do transmission service right. We use manufacturer-specified fluids and procedures, not generic shortcuts. Our certified techs provide comprehensive diagnostics before recommending any work. No unnecessary rebuilds, no surprise add-ons—just honest assessment and quality repairs to keep you moving.
Understanding your transmission
Your automatic transmission is one of the most sophisticated components in your car. Think of it as the bridge between your engine and wheels—it takes the power from your engine and delivers it smoothly to move your car forward or backward.
Here's how it works: Your engine spins at thousands of RPMs, but your wheels need to turn much slower (and with more power) to get you moving. The transmission uses a system of gears, fluid pressure, and a torque converter to make this happen automatically.
Think of transmission fluid like your car's blood—it needs to be clean and fresh to keep everything running smoothly. Without proper fluid, internal components wear out quickly and shifting becomes rough or impossible.
Long story short: healthy transmission = smooth, effortless driving.
When any of these components start failing, you'll feel it immediately.
Common Transmission Warning Signs
When your transmission isn't working properly, it usually gives you clear warning signs before major problems develop.
Common symptoms to watch for:
- Rough or delayed shifting - gears don't engage smoothly
- Check engine light - often transmission-related in modern cars
- Slipping gears - engine revs but car doesn't accelerate properly
- Strange noises - whining, grinding, or clunking sounds
- Fluid leaks - red or brown spots under your parked car
- Burning smell - overheated transmission fluid
Here's the thing: catching problems early saves thousands. A transmission fluid change costs much less than a complete rebuild or replacement.
Remember:
Your transmission is one of your car's most expensive components. Regular maintenance and early problem detection can extend its life by 100,000+ miles, while neglect often leads to complete failure by 150,000 miles.

Our Transmission Services
We provide comprehensive transmission care, from routine maintenance to complete replacement. Our goal is always to find the most cost-effective solution for your specific situation.
Services We Provide:
- Transmission Fluid Service - Complete fluid replacement with proper flushing procedures
- Transmission Diagnostics - Advanced computer and road testing to identify exact problems
- Solenoid Replacement - Repair shifting issues caused by faulty electronic components
- Valve Body Service - Address internal hydraulic control problems
- Transmission Replacement - Complete unit replacement when repair isn't cost-effective
Common Solenoid Problems We Fix:
Solenoids are electrical components that control gear shifting. When they fail, you'll notice specific symptoms:
- Stuck in certain gears - car won't shift out of 2nd or 3rd gear
- Shifts too late - engine revs high before changing gears
- Shifts too early - engine struggles and shakes from premature shifting
- Harsh shifting - gears engage with a jolt or bang
Fortunately, solenoids can often be replaced individually, offering a cost-effective alternative to major transmission work.
Why Different Cars Need Different Approaches:
- BMW and Audi have complex electronic controls requiring specialized diagnostic equipment
- Toyota and Honda CVT transmissions need specific fluids and service procedures
- Mercedes 7G-TRONIC and 9G-TRONIC systems require dealer-level diagnostic capabilities
- VW DSG dual-clutch transmissions have unique service requirements
- Ford and Nissan continuously variable transmissions need specialized knowledge
We follow manufacturer procedures exactly, using the right fluids and diagnostic tools for your specific transmission type.
When Do You Need Transmission Fluid Service?
Transmission fluid doesn't last forever. Over time, it breaks down from heat and contamination, losing its ability to protect internal components.
General guidelines:
- Conventional automatic: Every 30,000-60,000 miles
- CVT transmissions: Every 30,000-50,000 miles
- High-performance vehicles: Every 20,000-40,000 miles
- Severe driving conditions: More frequent service needed
Signs you need service now:
- Hard bumps or jolts when shifting - very noticeable to customers
- Car hesitates or jerks when accelerating - common experience
- Strange whining or grinding noises - they'll definitely hear this
- Takes too long to shift into gear - frustrating daily experience
Rebuild vs Replacement: Our Honest Approach
When major transmission problems occur, you have options. While we can perform rebuilds, we often recommend replacement for better long-term value.
Why we prefer replacement over rebuild:
- Reliability: Remanufactured units have all components renewed
- Warranty: Better coverage on complete units
- Cost-effectiveness: Often similar cost to complete rebuild
- Time: Faster turnaround for getting you back on the road
We'll always give you honest advice about the most cost-effective solution for your situation.
Quality service at fair prices
Complete auto care: from oil changes to engine swaps.

I went to Clarity Auto Care for a 30-point inspection before making a car purchase on a Saturday afternoon. The service was great and efficient. Sergei and his team took the time to fully explain all the repairs that needed to be done. They provided a clear inspection report with pictures and answered all my questions! I highly recommend them and will certainly come back for repairs. Thanks, Sergei!

When I found Clarity via Yelp business leads, I was in a serious bind trying to find an available mechanic with an available replacement radiator for my 2013 Nissan in between my multiple jobs (all of which require driving). Huge thank you to Sergei at Clarity Auto Care for his thorough, prompt service and communication! As a car novice, I'm always nervous to try a new repair shop but Sergei's calm, confident demeanor made me feel more at ease. The front lobby/waiting area is surprisingly spacious and relaxing (not something typical or expected in my experience with auto repair shops). I also noted a Carfax care certificate on display in the lobby which gave me further peace of mind that this business is recognized for its quality of service. The estimate process was simple and included detailed notes as well as pictures. Before beginning the repairs, Sergei answered all questions without hesitation or annoyance (something I've experienced before at other places). After the repairs were completed, Sergei further demonstrated his abilities & attention to details with helpful notes about the car's overall performance and potential repair needs for the future. He spoke candidly with me about the car's long term performance given its age and without trying to upsell me unnecessarily. I'm so grateful to have found Clarity and Sergei and would definitely return! PS This is also located less than a 10 minute walk from Belmont Caltrain which makes for much easier transportation while your car is in the shop!
