Operation
Upshifting
In the following instructions, it is assumed that the driver is familiar with oper-
ating heavy-duty trucks and tractors, and can coordinate the movement of the
shift lever and clutch pedal to make smooth gear engagements while upshift-
ing or downshifting. Always double-clutch when making lever shifts.
CAUTION: Never move the range lever or the splitter control button
with the shift lever in neutral while the vehicle is moving.
1. Move the shift lever, double-clutching, to the next gear position in LO
range.
Range shift - LO to HI Range Direct (4th to 5th DIR)
2. When in last gear position for LO range and ready for the next
upshift, pull up the Range Lever and move the shift lever, double-
clutching, to the next higher speed position according to your shift
pattern. As the shift lever passes through neutral, the transmission
will automatically shift from LO to HI range.
CAUTION: Never move the shift lever to the LO speed gear position
after HI range preselection, or at anytime the transmission is in HI
range.
Splitter shift - HI Range Direct to HI Range Overdrive (5th DIR to 5th OD)
3. Move the splitter control button into the forward/overdrive position.
4. Then, immediately, release the accelerator, depress the clutch pedal
once to break torque, release the pedal to reengage clutch, and
accelerate the engine. The transmission shifts from direct to over-
drive when synchronous is reached.
Combination Range shift and Splitter shift - HI Range Overdrive to HI Range
Direct (5th OD to 6th DIR)
5. Start a normal shift, move the shift lever, double-clutching, to the 6th
speed gear position.
