Pressure Switch
This switch is to detect the gear change completion
and hydraulic clutch operation, and it is equipped on the
GST valve.
This switch is turned ON when the pressure in the
GST valve becomes higher than 0.49 MPa (5 kgf/cm
psi) of the pilot pressure, and it is turned OFF at a
pressure lower than 0.34 MPa (3.5 kgf/cm

Oil Temperature Sensor
This sensor is to detect the temperature of
transmission fluid, and it is equipped on the GST valve.
This is provided to make correction for driving time
and current of proportional reducing valve in accordance
with the oil temperature. This is used to thermistor, and
it has such characteristics that its resistance decreases
at high temperature and increases at low temperature.

Traveling Speed Sensor
This sensor is to detect the traveling speed, and it is
equipped on the right bottom side of the differential case.
This sensor perceives tooth of the front wheel drive gear
(3) on the PTO drive shaft (2) and emits pulse. This
pulse is sent to the electronic instrument panel, and the
traveling speed is calculated by the coefficient which is
set according to the tire size. The data of traveling speed
is always sent to the ECU.
