What is a Transmission?by Reliable Transmissions on 07/09/13
The transmission is a mechanical component designed to transmit power from a vehicle’s engine to the drive axle, which makes the wheels drive the vehicle.
Your car’s transmission is the most complicated and least understood major component in your car or truck. In today’s cars, the transmission is a combination of sophisticated hydraulics and computer-controlled electronic components.
By varying the gear ratio, the transmission alters the levels of power and speed to the wheels. For example, in low ranges, the transmission provides more power and less speed; in high ranges, just the opposite is true. This reduces the load on the engine, while increasing the vehicle’s speed and fuel economy.
