TRANSMISSION OPERATION CONTINUED
Programmable Transmission Initial Gear Setting
The initial gear is the gear that engages when the transmission control switch is engaged in FORWARD or
REVERSE position without selecting a specific gear. Each direction can have only one initial gear, and each direc-
tion can use different initial gears. Initial gears can be the same as but not higher than what is set as maximum
gear. Initial gear setting can be changed using the Messenger system when transmission is in NEUTRAL and the
machine is stopped. Changes made are new defaults at time of change or after a power cycle.
Programmable Transmission Maximum Gear Setting
The maximum gear is the highest gear the transmission will shift into. Each direction can have only one maximum
gear, and each direction can use different maximum gears. For FORWARD position, gears 3 through 8 are avail-
able. In REVERSE Position, gears 3 through 6 are available. Initial gear setting can be changed using Electronic
Technician when transmission is in NEUTRAL and the machine is stopped. Changes made are new defaults at
time of change or after a power cycle
Transmission Modulator Control (inching pedal)
The transmission modulator control (inching pedal) disengages power to the wheels. Press pedal in order to
decrease power to the wheels. A sensor monitors pedal position and varies hydraulic pressure to direction
clutches. When the pedal is fully depressed, power to the wheels will be disengaged.
The inching pedal can be used in all load conditions and provides the operator with speed control between two dis-
tinct gears. This is useful when the operator demands high engine speed for quick implement control while varying
C AU T I O N
Avoid prolonged use of the inching pedal when moving heavy loads. Shift into lower gear
to match load condition. Failure to follow this caution may result in equipment damage.
· Do not use inching pedal as a clutch for directional changes. Machine is designed to
"shuttle shift". Failure to follow this caution may result in equipment damage.
If the inching function is used in high load conditions, the operator should shift into a gear matched for that load
condition. If constant stalling occurs, downshifting is advisable.
