Engines vs Transmissions

Engines vs Transmissions

Engines generate the power needed to move your car, while transmissions control how that power reaches the wheels.

Engines create combustion power; transmissions multiply and route that torque to the driveline.

  • Engine symptoms: knocking, low compression, excessive oil consumption.
  • Transmission symptoms: slipping, delayed shifts, burnt fluid.
  • Always confirm VIN, engine code, and transmission tag before ordering.
