A transmission is a complex mechanism that ultimately helps your vehicle move. The engine creates a fast speed of rotation that does not work when starting your vehicle or at very low speeds. This is where the transmission comes in; it utilizes gears to reduce the engine's speed, harnessing its power or torque so that it will help the wheels turn. Contrary to popular belief, a transmission is not an engine; they are two separate mechanisms that work in tandem to make a vehicle do what it does best – move!
