How do I know if I have a transmission problem?

Transmission issues can show up in several ways. Common signs your vehicle may need transmission service include the following:

  • Check engine light or check transmission light
  • Low or leaking transmission fluid
  • Unusual noises coming from the transmission
  • Transmission slipping between gears
  • Difficulty moving the vehicle or complete transmission failure

If you notice any of these symptoms, we recommend having your vehicle inspected by a qualified technician to address potential transmission problems early.

    What is preventive maintenance?

    Preventive maintenance is essential to keep your vehicle running efficiently and to prevent costly repairs. Regular maintenance can include oil changes, tire checks, brake inspections, and fluid top-offs. In a recent survey:

    • 38% of cars had low or dirty engine oil
    • 54% had underinflated tires
    • 28% needed better cooling protection
    • 19% required new belts
    • 16% had dirty air filters
    • 10% had contaminated brake fluid
    • 17% were overdue for a transmission service

    By staying on top of maintenance, you help extend your vehicle’s lifespan and enhance safety.

    How Can I Track Routine Maintenance?

    Maintaining a clear service schedule helps prolong your vehicle’s life and reduces the risk of unexpected issues. If you prefer, Sampson Transmission can maintain your schedule, ensuring timely reminders for essential services that keep your vehicle in top shape.

    Does It Matter Where I Take My Vehicle for Service?

    Yes. Certified mechanics undergo regular training on the latest vehicle systems and diagnostic tools. This expertise allows them to accurately diagnose issues and recommend effective solutions. Our team at Sampson Transmission uses:

    • Electronic scopes for monitoring sensor signals
    • Diagnostic scanners to communicate with vehicle computers
    • Tech-info resources for accessing wiring diagrams, technical bulletins, and more

    Choosing a certified mechanic ensures precise diagnostics and reliable repairs, reducing the risk of misdiagnosis and unnecessary expenses.

    Why Won’t My Car Start?

    A car that won’t start can have multiple causes. If there’s no sound when you turn the key, the issue is likely in the starting circuit, which includes the starter motor, battery, switches, and wiring. While replacing the battery is often the first step, a full system check is essential for an accurate diagnosis.

    If the engine cranks but doesn’t start or stay running, there may be issues with the fuel system, ignition system, or mechanical issues such as compression, or timing. This situation requires an in-depth engine and computer diagnostic to pinpoint the root problem.

    How Often Should I Replace My Spark Plugs?

    While many manufacturers recommend replacing spark plugs around 100,000 Kilometers, we suggest a replacement interval between 60,000 to 80,000 Kilometers to avoid premature wear on other parts like ignition coils. Replacing spark plugs sooner reduces the risk of costly coil replacements and ensures optimal engine performance.

    What Causes Brake Pulsation?

    Brake pulsation—a noticeable up-and-down movement of the brake pedal—can result from two scenarios:

    • ABS engagement on slippery roads, which is normal
    • Warped rotors on dry roads, which is a cause for concern

    If the rotors are warped, we can replace them, to ensure safe and smooth braking.

    Why Did My Check Engine Light Turn On?

    A check engine light indicates that the car’s computer has detected a problem in the fuel, ignition, or emissions system. It’s important to address this promptly, especially if the light starts flashing, as this could signify an engine misfire that may damage the catalytic converter if ignored.

    Which Parts Need Regular Replacement, and When?

    Your owner’s manual provides specific guidelines for part replacement intervals. Common items include oil, filters, brake pads, and spark plugs. Following these schedules not only keeps your vehicle running smoothly but also protects your warranty.

    How Can I Keep My Vehicle’s Warranty Valid?

    To keep your warranty intact, follow the service intervals listed in your Owner’s Manual or Warranty Booklet, and keep accurate records of each service, including dates, parts installed, vehicle mileage, and receipts.

    Do I Have to Go to My Dealer for Service to Maintain My Warranty?

    No, you’re free to use any reputable mechanic or repair shop for routine maintenance, and your warranty will remain valid.

    Am I Required to Use Manufacturer Parts to Retain My Warranty?

    No, automakers cannot require the use of their parts for vehicle maintenance. Quality aftermarket parts are an acceptable choice, allowing you to maintain your warranty while keeping costs down.
