What is the purpose of an automotive transmission?

[JanelleRose]

An automotive transmission can alter the gear ratio, expanding the range of torque and rotational speed variations in the drive wheels to adapt to frequently changing driving conditions. It also enables the engine to operate under favorable conditions (higher speed with lower fuel consumption). Additionally, it allows the vehicle to reverse while maintaining the engine's rotational direction. The transmission can also utilize neutral gear to interrupt power transmission, enabling the engine to start, idle, and facilitating gear shifting or power output. Below is additional information: 1. As a crucial component in a vehicle's drivetrain system, the automotive transmission compensates for the fact that piston engines cannot achieve the wide range of torque and speed variations required by vehicles. 2. Transmission repair is one of the most complex systems in overall vehicle maintenance.
