USING TRANSMISSION GEAR RANGES AND COMBINATIONS
Main Transmission. Road, load, and traffic conditions sometimes require that you move the main
transmission range selector lever (1) to a position that will give a lower drive range. For example,
if you shift to 4 (2-4 range) or 3 (2-3 range), you can limit the transmission to automatically shift-
ing only within these lower ranges to meet the existing driving conditions. When the driving con-
ditions are back to normal, return the range selector lever (1) to normal driving range position (D).
When driving up a steep grade, or pulling through mud or snow, move the main transmission range
selector lever (1) to the 2 (2nd gear hold) position. In the 2 position, no automatic upshifting or
downshifting will occur (unless engine overspeed occurs). For more severe loaded grade conditions,
move the main transmission range selector lever (1) to the 1 (1st or low gear) position. This
position will give the most pulling power, engine braking effect, and hydraulic retarder effect
you can get.
