What the Transmission Does

Your vehicle’s transmission transfers power from the engine to the wheels and controls how that power is applied.

It helps your vehicle:

  • Shift gears smoothly
  • Accelerate properly
  • Maintain efficient performance

Transmission systems can vary depending on the vehicle, including automatic, manual, and continuously variable transmissions (CVT).

Some common signs include:

  • Delayed or rough shifting
  • Slipping gears
  • Grinding or unusual noises

  • Loss of power or hesitation

These symptoms can have more than one cause. Proper testing is needed to confirm the issue. If your vehicle is also experiencing drivability concerns, visit our engine performance page for more information.
