The Power Train Transmission, often referred to simply as the transmission, is a key component of a vehicle's powertrain system. The primary function of the powertrain transmission is to transfer power from the engine to the wheels at different speeds and torque levels. It provides various gear ratios to match the engine's power output to the desired speed and load conditions.

Attributes:
Provides the driver with direct control over gear selection.
Lower gear ratios provide more torque while higher gear ratios offer higher speeds and better fuel efficiency.
Designed for ease of maintenance and serviceability.

Applications:
The Power Train Transmission is a critical component of a vehicle allowing for the efficient transfer of power from the engine to the wheels and is mainly used in Cat® 777, 777E, and 777G Trucks.
