NOTE:
The level of ATF varies with fluid temperature. Pay
attention to the ATF temperature when checking
ATF level.
1) Raise the ATF temperature by driving a distance
of 5 to 10 km (3 to 6 miles). Otherwise, idle the en-
gine to raise ATF temperature to 70 — 80°C (158
— 176°F) on Subaru Select Monitor. <Ref. to
5AT(diag)-15, READ CURRENT DATA, OPERA-
TION, Subaru Select Monitor.>
2) Park the vehicle on a level surface.
3) After selecting all positions (P, R, N, D), set the
select lever in “P” range. Idle the engine for 1 or 2
minutes, and measure the ATF level.
4) Make sure that the ATF level is between upper
and lower marks of the HOT side.
5) If the ATF level is below the lower mark, add rec-
ommended ATF until the fluid level is between up-
per and lower marks.
CAUTION:
•Be careful not to exceed the upper level.
•When the transmission is cold, be careful not
to add ATF to the upper level on HOT side.
Overfilling of ATF may cause oil splashing.
6) Raise the ATF temperature by driving a distance
of 5 to 10 km (3 to 6 miles). Otherwise, idle the en-
gine to raise ATF temperature to 70 — 80°C (158
— 176°F) on Subaru Select Monitor. <Ref. to
5AT(diag)-15, READ CURRENT DATA, OPERA-
TION, Subaru Select Monitor.>

Stall Test
AUTOMATIC TRANSMISSION
5. Stall Test
A: INSPECTION
NOTE:
The stall test is extremely important in diagnosing
the condition of an automatic transmission and en-
gine. It should be conducted to measure the engine
stall speeds in “R” and “2nd of manual mode”.
Purposes of the stall test:
•Operational check of the automatic transmission
clutch
•Operational check of the torque converter clutch
•Engine performance check
1) Check that the throttle valve fully opens.
2) Check that the engine oil level is correct.
3) Check that the coolant level is correct.
4) Check that the ATF level is correct.
5) Check that the differential gear oil level is cor-
rect.
6) Raise the ATF temperature to 70 to 80°C (158 to
176°F) by driving a distance of 5 to 10 km (3 to 6
miles). Confirm the ATF temperature on Subaru
Select Monitor. <Ref. to 5AT(diag)-15, READ CUR-
RENT DATA, OPERATION, Subaru Select Moni-
tor.>
7) Place the wheel chocks at the front and rear of
all wheels and apply the parking brake.
8) Move the select lever to ensure it operates prop-
erly, and then set to the “2nd gear of manual
mode”.
9) While stepping hard on the brake pedal, gradu-
ally step on the accelerator pedal.
10) When the engine speed is stabilized, quickly
record the engine speed and release accelerator
pedal.
11) Shift the select lever to “N” range, and cool
down the engine by idling it for more than one
minute.
12) Perform the procedure for “R” range in the
same way as “2nd on manual mode”.
NOTE:
•Do not continue the stall test for MORE THAN
FIVE SECONDS at a time (from fully closed throttle
to fully open throttle until stall speed reading). Do-
ing so will make the engine oil and ATF deteriorate
and the clutch and brake to be adversely affected.
•After performing the stall test, be sure to cool
down the engine for at least one minute with the se-
lect lever set in “P” or “N” range, and at an idle
speed of 1,200 rpm or less.
•If the stall speed is higher than the specified
range, attempt to finish the stall test in as short a
time as possible, in order to prevent the automatic
transmission from sustaining damage.
Stall speed (at sea level):
2,300 — 2,800 rpm

Time Lag Test
AUTOMATIC TRANSMISSION
6. Time Lag Test
A: INSPECTION
NOTE:
When the select lever is shifted while the engine is
idling, there will be a certain time elapse or lag be-
fore shock is felt. Using this, check the condition of
forward brake, reverse brake, 1st one-way clutch,
forward one-way clutch and 3rd one-way clutch.
•Perform the test at normal operation fluid tem-
perature of 70 — 80°C (158 — 176°F).
•Be sure to allow a one minute interval between
tests.
•Make three measurements and take the average
value.
1) Fully apply the parking brake.
2) Start the engine.
Check the idle speed (A/C OFF).
3) Shift the select lever from “N” to “D” range. Using
a stop watch, measure the time-lag from shifting
the lever until the shock is felt.
Time-lag
Specification: 1.2 sec. or less
If “N” → “D” time-lag is longer than specification:
•Line pressure too low
•Forward brake worn
•One–way clutch not operating properly
4) In the same manner, measure the time lag of “N”
→ “R”.
Time-lag
Specification: 1.5 sec. or less
If “N” → “R” time lag is longer than specification:
•Line pressure too low
•Reverse brake worn

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.
