LINE PRESSURE TEST
This test is to check oil pressure system for operation by measuring
oil pressure in oil pressure line. Make sure to perform this test only
when transmission fluid is at normal operating temperature.
NOTE:
D Make sure that transmission fluid level is between FULL
HOT and LOW HOT marks on oil level gauge at normal oper-
ating temperature
(155–1765F) of fluid. (Refer to "Fluid level" in this section.)
D Check that transmission is free from fluid leakage.
1) With engine at stop, remove plug and connect oil pressure
gauge to plug hole.
Special Tool
(A): 09925-37811-001
2) Install tachometer.
3) Apply parking brake and block vehicle wheels.
4) With selector lever shifted to P range, start engine.
5) Depress brake pedal fully.
6) Shift selector lever to D range and check oil pressure with en-
gine running at idling speed and at stall speed respectively.
7) Repeat the same check as in step 6) with selector lever shifted
to R range.
CAUTION:
Do not run engine at stall more than 5 seconds contin-
uously, for oil temperature may rise excessively high.
8) If line pressure is within respective specification in table below,
oil pressure system is in good condition.
