Modes

Economy Mode

Selecting the Economy mode will change the speed of the transmission shifts in order to provide earlier upshifts. This will enhance fuel economy.

PTO ON/OFF

Selecting the PTO mode will enable the control of PTO devices.

Note: This functionality is only available if the PTO is controlled by the transmission ECM.

Hold

When the Hold mode switch is chosen, the transmission shift points will be widened so that the present gear will be held for a longer duration before an upshift or downshift event. When the Hold mode switch is depressed again, the transmission will shift normally.

Quick Gear Limit

The Quick Gear Limit feature utilizes the shift pad MODE switch activation to indicate that the transmission should not upshift beyond 1st gear. This feature can be used to effectively limit vehicle speed during vehicle maneuvering or stop-and-go driving during refuse applications. Further, the reverse range may be inhibited during Quick Gear Limiting, if desired. The Quick Gear Limit feature only inhibits upshifts past 1st gear. If the transmission is above 2nd gear, the transmission will continue to operate normally until 2nd gear is attained, at which time upshift will normally be inhibited. Vehicle operation conditions sufficient to overspeed the engine in 1st gear will result in an engine-protection upshift to higher gears.

Oil Level Check Sequence

The CX31 transmission is equipped with an electronic oil level sensor (internal to the transmission) in order to make transmission fluid level checking more convenient. To initiate the oil level check sequence, press and hold the upward arrows and downward arrows simultaneously. This will begin a two minute countdown. Refer to Illustration 3.

Note: If the user presses and holds N or Up and Down arrows at any time, the user will exit the mode. Refer to Table 1.
