Operation
Warning: UltraShift PLUS initiates upshifts from MANUAL and LOW for
engine over speed protection. Some engines do not use the engine overspeed
protection.
• The system will automatically shift or inhibit shifts to prevent over-
speed or under-speed of the engine.
• The transmission may also deny a shift while ascending or descend-
ing grades if the load of the vehicle, and grade of the terrain in com-
bination with the drivetrain ratio and engine torque will fall outside of
the acceptable range to perform a shift. If the shift is denied it will
sound a tone.
Transmission Manual Override:
• If the vehicle is being back driven and the engine is approaching a
higher than normal level, the transmission system will override the
MANUAL position and perform and upshift.
• If the start gear is changed and it causes the engine to lug at takeoff,
the transmission system will override the MANUAL position and
select the best available gear.
Note: *If the driver attempts to select a non-neutral mode without depressing
the service brakes the transmission will not shift into gear and the driver
will have to return to Neutral and depress the brakes before selecting the
desired mode again.
Important: If the driver depresses and holds both pedals (even if done acci-
dentally) the launch will be abrupt and the engine and brake forces may rock
and bounce the vehicle. Releasing either pedal will stop this immediately.
