Overview
John Deere continues to use its proven transmissions with 8 forward and 8 reverse gears. The Motor Grader offers two options in manual or Auto-Shift Plus. Auto-Shift PLUS adds additional functionality for the operator by modulating the clutches and reducing/removing the need for the inching pedal. This simplifies the needed operator inputs for starting and stopping the machine. Auto-Shift plus also offers Hill Hold and adjustable RPMs to further enhance their experience while plowing snow at high speeds or fine grading around obstacles.
Event Based Shifting
Event Based Shifting (EBS) is transmission shifting logic that senses the load on the engine as well as other inputs to determine the optimum shift time when the operator selects a new gear. The inching pedal is not required when performing directional changes (shuttle shifting) or changing gears. This logic gives John Deere the edge on transmission performance in grader applications.
Auto-Shift Plus
Allows operators to seamlessly transition from a stop to full speed without shifting or using the inching pedal. This is achieved by modulating the torque through the transmission, instead of the transmission acting as a direct drive. Auto-Shift automatically shifts between gears 4-8 for roading applications. Auto-Shift Plus functionality can be configured in the monitor.

Adjustable Auto Shift Plus
This feature allows the operator to set the minimum/idle to 800/1000/1200 rpm while in gear using Auto Shift Plus. Auto Shift Plus will still maintain the ability to stop the machine and maintain low ground speed while using only the brake and throttle, but the increased engine rpm allows for increased hydraulic flow. This allows the operator to have more control of the machine speed while providing additional hydraulic capacity.

Hill hold
While using Auto-Shift Plus when coming to a stop on a hill, the transmission will hold the machine and then transition back into gear when the throttle is pressed. The state of hill hold will be represented in the monitor by the following icons where green is enabled.
