Introduction
Your machine is equipped with a countershaft transmission. These transmissions have eight forward speeds and six reverse speeds. These speeds are electronically controlled by the electronic control module (ECM).
The transmission is located on the left rear side of the motor grader. The transmission is mounted as a single unit onto the engine flywheel housing. The engine is mounted to the frame.

The power from engine (4) is transmitted directly to transmission (1). When the transmission modulator control is released, power is transferred to drive shaft (2). Drive shaft (2) transmits power from the transmission output shaft to the differential and bevel gear (3). Differential and bevel gear (3) transfers power to final drives (5). Final drives (5) transfer power to chains (6). Chains (6) drive wheels (7).
