TRANSMISSION SYSTEM
0003
1. The electronic clutch pressure control (ECPC) transmission has eight forward speeds and six reverse speeds.
The transmission is electronically controlled and hydraulically actuated. The transmission/chassis ECM is
mounted on the rear of the transmission. The ECM allows the operator to manually shift the transmission
based on the shift controls located on the left joystick. Power flows through the transmission directly to the
differential and bevel gear.

2. The differential and bevel gear, which are housed inside the rear axle, are used to transfer power from the
transmission to the final drives. The differential and bevel gear together make up the rear axle. The differential
allows the wheels to turn at different rates of speed when the machine is going through a turn, and it can be
locked by the differential lock valve.
