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.
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

4) Attach the magnet at the specified position of the
oil pan.
5) Apply liquid gasket to the oil pan.
Liquid gasket:

6) Install the oil pan by equally tightening the bolts.
Tightening torque:
5 N·m (0.5 kgf-m, 3.7 ft-lb)
7) Pour ATF through the oil charge pipe.
Specified and recommended fluid:
Capacity:
Fill with the same amount of ATF as drained.
8) Check the ATF level.
9) Perform Clear Memory 2 operation.

10) Perform the inspection with driving the vehicle
at the end of repair work, and make sure there is no
faulty as below;
•Excessive shift shock
•Oil leakage from the transmission body, etc.
•Occurrence of noise caused by interference etc.
NOTE:
If excessive shift shock is felt, execute advance op-
eration of learning control.

eign matters.

Basic Diagnostic Procedure
AUTOMATIC TRANSMISSION (DIAGNOSTICS)
1. Basic Diagnostic Procedure
A: PROCEDURE
Step Check Yes No
1CHECK PRE-INSPECTION.
1) Ask the customer when and how the trou-
ble occurred using the interview checklist.
2) Before performing diagnosis, inspect the
following item which might influence the AT
problems.
•General inspection
•Oil leakage
•Stall speed test
•Line pressure test
•Transfer Clutch Pressure Test
•Time Lag Test
•Road Test
•Inhibitor Switch
Is the unit that might influence
the AT problem normal?
Go to step 2.Repair or replace
each item.
2CHECK SPORT INDICATOR LIGHT.
After the ignition switch is turned to ON, wait
for at least 2 seconds.
Does the SPORT indicator
light illuminate?
Go to step 4.Go to step 3.
3CHECK SPORT INDICATOR LIGHT.
1) Turn the ignition switch to OFF.
2) Check the SPORT indicator light.
Light Display.>
3) After the ignition switch is turned to ON,
wait for at least 2 seconds.
Does the SPORT indicator
light blink?
Go to step 4.Go to step 5.
4CHECK DTC.
Read the DTC.
NOTE:If the communication function of Subaru Select
Monitor cannot be executed normally, check
communication circuit.

3. CLEAR MEMORY MODE
NOTE:
To clear the previous DTC, use {Clear Memory},
and to clear the learned value, use {Clear Memory
2}.
1) Check that the select lever is in “P” range.
2) On the «Main Menu» display screen, select the
{Each System Check} and press the [YES] key.
3) On the «System Selection Menu» display
screen, select the {Transmission} and press the
[YES] key.
4) Press the [YES] key after the information of
transmission type is displayed.
5) On the «Transmission Diagnosis» display
screen, select the {Clear Memory} and press the
[YES] key.
NOTE:
If {Clear Memory 2} is selected and performed,
DTC are not cleared.
