What is the main drive gear in a transmission?

The main drive gear in a transmission, often referred to as the output gear, is the gear that transmits power from the transmission to the vehicle's driveshaft. It is crucial for converting the engine's rotational motion into usable torque for the wheels. The main drive gear typically works in conjunction with other gears in the transmission to provide different gear ratiOS, allowing for varied speed and torque outputs depending on driving conditions.
