Transmission parts for Volvo trucks 

A drivetrain is a system of transmission devices for transmitting torque from the engine to the drive wheels of a vehicle. The transmission system includes: gearbox, driveshafts, transfer case, axle shafts, differential, semi axis, and constant-velocity joints. The layout of the drivetrain system varies depending on which axle is the drive: the front, rear, or all axles of the vehicle. The gearbox comes in manual or automatic.

The AT has received many designs and modifications and currently continues to technically evolve. More
