Transmission Direction and Speed Control

Usage:

432D BLD

Direction Selector




Illustration 1g00726726

The transmission direction control lever is located on the steering console.


FORWARD (1) - Move the transmission lever upward. The machine will move forward.


NEUTRAL (2) - The machine should not move when the transmission lever is in neutral.


REVERSE (3) - Move the transmission lever downward. The machine will move in reverse.

Forward directional changes and reverse directional changes are possible while the machine is moving. However, reducing the engine speed is recommended, when directional changes are being made. Reducing the machine ground speed and/or braking is recommended, when directional changes are being made. This permits operator comfort and maximum service life of the power train components.

Speed Selector




Illustration 2g00726741

The transmission has five forward speeds and three reverse speeds. Rotate the transmission lever to the desired gear speed:

"1" - First Speed

"2" - Second Speed

"3" - Third Speed

"4" - Fourth Speed

If the transmission is in fourth gear and the direction control is in the FORWARD position, the transmission will shift into fifth gear automatically. The autoshift control in the manual mode will prevent the transmission from shifting to fifth gear. If the transmission is in fourth gear and the direction control is in the REVERSE position, the transmission will only shift into the third gear.

The transmission can be manually downshifted by using the neutralizer/downshift switch that is located on the loader control.

Neutralizer/Downshift switch for the pilot loader control

Press the downshift switch and release the downshift switch on the loader control. The transmission downshifts one gear speed, provided that an engine overspeed would not occur.

Note: The initial transmission downshift will always respond. Subsequent downshifts will occur provided that an engine overspeed would not occur.

Press the downshift switch and release the downshift switch on the loader control for continued downshifts until the machine is in first gear. Automatic downshifts into first gear are not allowed. The normal autoshift function continues in five seconds after the downshift switch is released.
