An automotive transmission gearbox is a crucial component of a vehicles powertrain that transmits power from the engine to the wheels while regulating speed and torque. It allows the driver to change gears efficiently, optimizing performance, fuel efficiency, and drivability. Transmission gearboxes come in various types, including manual transmissions (MT), automatic transmissions (AT), continuously variable transmission (CVT), and electric vehicle (EV) transmissions, each designed to meet different driving needs and vehicle applications.
