Electrohydraulic ControlsThe autoshift switch determines if the transmission will be shifted manually or if the transmission will be shifted automatically. The autoshift switch also determines the functionality of the left service brake pedal.Reference: For additional information about the functionality of the left service brake pedal, refer to the Operation and Maintenance Manual, "Service Brake Control" for the machine that is being serviced.Manual Shifting
Move the autoshift switch into the MANUAL position (1). Depressing the left service brake pedal will cause the transmission to downshift. If the transmission neutralizer has not been disabled, the transmission will also neutralize as the machine slows down.The operator must use the transmission speed selector in order to change transmission speeds.Reference: For additional information about shifting the transmission, refer to the Operation and Maintenance Manual, "Transmission Control" for the machine that is being serviced.Automatic Shifting (Electrohydraulic Controls)
Move the autoshift switch into one of the four automatic positions (2). When the autoshift switch is in the 2, 3, or 4 position, the lowest allowable speed for the transmission is SECOND speed. The transmission will shift into SECOND after a change in direction. When the autoshift switch is in the 1 - 4 position, the lowest allowable speed for the transmission is FIRST speed. The transmission will shift into FIRST after a change in direction.Note: The machine can be electronically configured by a Caterpillar dealer to start in SECOND after a change in direction when the autoshift switch is in the 1 - 4 position.Depressing the left service brake pedal will cause the transmission to downshift. If the transmission neutralizer has not been disabled, the transmission will also neutralize. Fully releasing the left service brake pedal will allow the machine to return to automatic shifting.Downshifting (Electrohydraulic Controls)

Transmission speed selectorManual Shifting
Press the bottom of the transmission speed selector that is located on the left side of the steering wheel in order to downshift the transmission. The transmission speed selector can be used to downshift from SECOND to FIRST in order to load the bucket. The transmission will shift into FIRST speed in order to back away from the pile.Automatic Shifting
Press the bottom of the transmission speed selector that is located on the left side of the steering wheel in order to downshift the transmission. The transmission speed selector can be used to downshift from SECOND to FIRST in order to load the bucket. The machine will remain in FIRST speed until either the machine changes direction or the operator manually upshifts the machine. Note: The transmission will only downshift if an engine overspeed will not occur. Reference: For additional information about shifting, refer to the Operation and Maintenance Manual, "Transmission Control" for the machine that is being serviced.
