The transmission is hydro-mechanical where all gears are in constant mesh and the designation is HTE204 for L110E and

HTE205 for L120E.

There is a single-stage hydraulic torque converter between engine and transmission.

Front and rear axles have fully floating axle shafts with planetary gears in the hubs. The front axle is equipped with a

differential lock.

The service and parking brakes on the machine are wet type disc brakes.

The service brakes are integrated in the respective wheel hubs and the parking brake is located on the output shaft in the
