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

Engines create combustion power; transmissions multiply and route that torque to the driveline. Replacing the wrong component wastes time and money.

Engine symptoms: knocking, low compression, excessive oil consumption, failed emissions.
Transmission symptoms: slipping, delayed shifts, burnt fluid, codes for solenoids or TCM.
Always confirm VIN, engine code, and transmission tag before ordering a reman unit.

Contact our parts specialists if you need help matching a unit to your VIN.
