prioritizing work effectiveness.
Under auto shifting mode, the gear is shifted in
regular timing.
Shift Change Delay Mode
When travel mode selector (12) is set in AUTO 1 or AUTO 2
while shift switch (11) is in 3rd or 4th speed position, the
shift up timing in 2nd speed

3rd speed is delayed.
Loading work can be easily done in 2nd speed position.
Shift Up Delay
Forward traveling : The gear shifts up when traveling the
machine at high speed in 2nd speed
position for 8 seconds or longer.
However, the gear will not shift while
the lift arm is raising. When the bucket
is at transportation or traveling height,
the shift up timing delay operates
once. When the bucket is at digging
position (near the ground), the shift up
timing delay always operates.
Reverse traveling : The gear shifts up when traveling the
machine at high speed in 2nd speed
position for 8 seconds or longer.
The shift up timing delay operates
regardless of the bucket height.
Capability to activate or not activate the shift change delay
mode is selected at the transmission setting screen on the
monitor.

NOTE: The shift up delay will not operate when shifting up
from 2nd speed to 2nd L-UP.
