Signs You Need Transmission Service

Transmission problems often start small and become more noticeable over time. Schedule an inspection if you notice:

• Delayed shifting or hesitation when accelerating

• Hard shifting or “clunking” between gears

• Transmission slipping (RPMs rise but the car doesn’t accelerate normally)

• Shuddering or vibration during shifts

• Burning smell or dark/burnt fluid

• Fluid leaks under the vehicle

• Check Engine Light or transmission-related warning light

• Strange noises in gear (whining, humming, grinding)

If you’re unsure if it’s safe to drive, call us—some symptoms can indicate a more urgent issue.

Transmission Services We Offer

Transmission problems can come from fluid condition, leaks, electronic controls, sensors/solenoids, or internal wear. We start with diagnosis and recommend the right path based on what we confirm.

Transmission Diagnostics

• Professional scan + drivability evaluation

• Identify shifting, slipping, shudder, and warning light causes

• Confirm whether the issue is mechanical, hydraulic, or electronic

Transmission Fluid Service

• Fluid condition check and service recommendations

• Help prevent premature wear and overheating

• Address shifting quality concerns related to fluid degradation

Transmission Leak Repair

• Identify leak source (pan gasket, seals, cooler lines, etc.)

• Repair leaks to protect the transmission from low-fluid damage

Shift & Drivability Concerns

• Harsh shifts, delayed shifts, slipping, or intermittent shifting issues

• Diagnose control-related issues (sensors/solenoids/electronic faults) and mechanical causes

If the issue turns out to be outside the transmission (engine performance, mounts, driveline, etc.), we’ll tell you—because fixing the wrong system wastes money.
