Shift High Range and Low Range
When the car is stops (less than 2km/h or 1.2 mph and
less than 1500 rpm), the AT selector position is neutral,
the brake is applied, and the TOD switch is changed to 4L
from TOD (or to TOD from 4L), the high-low shift motor
starts by power applied from the TOD control unit and
turns the shift shaft through the worm gear.
The shift shaft turns the shift cam through the torsional
spring.
The end of the shift cam moves the lockup shift fork and
the spiral groove on the outside of the shift cam slides the
high–low shift fork.
