JUDGEMENT OFLINE PRESSURE TEST

• Ifline pressure doesnotrise, firstcheck tomake surethat
throttle wireisconnected properly.

GOVERNOR PRESSURETESTING

1. Check
AIT
and engine fluidlevels. Ifnecessary, addfluid.
2 .. Drive vehicle forabout 10minutes untilengine oiland ATF
reach operating temperature.

ATF operating temperature:
50 -80°C (122-176°F)

3. Install pressure gaugetogovernor pressureport.
4. Set parking brakeandblock rearwheels.
5. Jack upfront wheels.
6. Set selector leverinDposition anddrive vehicle.

Be careful ofrotating wheels.
•

Governor pressure:
• Governor pressureisnot generated whenvehicle is
stopped. (frontwheels arenotrotating.)
• Governor pressurerisesgradually inresponse tovehicle
speed. (frontwheel rotating speed.)

If not, check governor valveassembly. RefertoAT-36.
