Komatsu Advanced Transmission with Optimum Modulation Control System

Skip Shift Funtion

Automatically selects a gear position depending on the slope grade when driving uphill without shifting down through each gear. It reduces the number of downshifts, makes the driving smoother, improves the operator’s comfort and reduces material spillage.

Auto Idle Shutdown

In order to reduce unwanted idle time, Komatsu machines feature Komatsu Auto Idle Shutdown. This function will shut the engine off and apply the parking brake and hydraulic lock after a preset idle time limit
