Line Pressure Test
AUTOMATIC TRANSMISSION
7. Line Pressure Test
A: MEASUREMENT
NOTE:
If the clutch or brake shows a sign of slippage, or
shifting interval is not correct, check the line pres-
sure.
•Excessive shock during up-shift may be due to
the line pressure being too high.
•Slippage or inability to operate the vehicle may,
in most cases, be due to loss of oil pressure for the
operation of clutch, brake or control valve.
1) Set the vehicle on a lift.
2) Remove the under cover.
3) Remove the test plug and install the ST.
ST 498897200 OIL PRESSURE ADAPTER
4) Set the ST1 and ST2.
ST1 498897200 OIL PRESSURE ADAPTER
ST2 498575400 OIL PRESSURE GAUGE
5) Lower the vehicle, and pull ST1 and ST2 into the
vehicle.

6) Connect the Subaru Select Monitor to the data
link connector and read the current data.

TION, Subaru Select Monitor.>
7) Perform the line pressure test.
NOTE:
•Do not perform the line pressure test for more
than 5 seconds at a time. Doing so will make the
engine oil and ATF deteriorate and the clutch and
brake to be adversely affected.
•After performing the line pressure test, be sure to
cool down the engine for at least one minute with
the select lever set in “P” or “N” range and with the
idle speed at 1,200 rpm or less.
•Adjust the throttle valve angle in order to match
the “P/L Solenoid Pressure” displayed on the Sub-
aru Select Monitor.
