LINEPRESSURE TESTPROCEDURE
1. Check AfTand 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 gaugetoline pressure port.
4. Set parking brakeandblock wheels.
Continue todepress brakepedalfullywhile performing line

Refer toSOS, AT-166.
JUDGEMENT OFLINE PRESSURE TEST
• Ifline pressure doesnotrise, firstcheck tomake surethat
throttle wireisconnected properly.
1) When linepressure whileidling
is
low atall positions ("D",
"2", "1", "R"and"P"), theproblem maybedue to:

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.
