Road Test
4. Road Test
A: INSPECTION
1. GENERAL PRECAUTION
Road tests should be conducted to properly diag-
nose the condition of the automatic transmission.
NOTE:
When performing the test, do not exceed posted
speed limit.
2. D RANGE SHIFT FUNCTION
Check shifting between 1st ←→ 2nd ←→ 3rd ←→
4th while driving on normal city streets.
3. D RANGE SHIFT SHOCK
Check the shock level when shifting up during nor-
mal driving.
4. KICK-DOWN FUNCTION
Check kick-down for each gear. Also check the
kick-down shock level.
5. ENGINE BRAKE OPERATION
 Check the 3rd gear engine brake when shifting
down from D ←→ 3rd range while driving in 4th
gear of D range [50 — 60 km/h (31 — 37 MPH)].
 Check the 2nd gear engine brake when shifting
between 3rd ←→ 2nd range while driving in the 3rd
range of 3rd gear [40 — 50 km/h (25 — 31 MPH)].
 Check the 1st gear engine brake when shifting
between 2nd ←→ 1st range while driving in the 2nd
range of 2nd gear [20 — 30 km/h (12 — 19 MPH)].
6. LOCK-UP FUNCTION
 Check that rpm does not change sharply when
the axle pedal is lightly depressed when driving on
flat roads at 60 km/h (37 MPH).
 Check slip lock-up with following procedure.
Subaru Select Monitor is needed for checking (EC,
EK model).
Before start checking, check that the DTC is not ex-
isted using Subaru Select Monitor. When the DTC
is existed, perform the collective action with DTC
and check that the DTC is not existed again, and
then start the checking.
1) The check performed on flat and straight road or
free roller.
NOTE:
 Slip lock-up does not operate when the vehicle is
lifted up, because of not occurring surface resis-
tance.
 Also checking on the free roller, check with de-
pressing foot brake lightly to make the checking
easier, because the surface resistance will be defi-
cient2) Connect the Subaru Select Monitor.
3) Check ATF temperature using Subaru Select
Monitor.
NOTE:
 ATF temperature is between 50 — 100°C (122
— 212°F).
 When the temperature is low, warm-up the ATF
by running the vehicle or etc.
4) Start the engine, and make the lock-up duty be
able to read on data display of Subaru Select Mon-
itor.
5) 35 — 40 Drive the vehicle at a constant speed of
35 — 40 km/h (22 — 25 MPH).
6) Read the lock-up duty while vehicle is running.
Standard value:
25 — 45%
NOTE:
On the free roller, the value sometimes lowers.
 Slip lock-up control is not operating when the
lock-up duty is less than 5%, or when the lock-up
duty goes down immediately after starts rise. On
these cases, improper ATF or deterioration of ATF
may be the cause. Check the amount of ATF or re-
place them, and then recheck it.
7. P RANGE OPERATION
Stop the vehicle on an uphill grade of 5% or more
and shift to “P” range. Check that the vehicle does
not move when the parking brake is released.
8. NOISE AND VIBRATION
Check for unusual sounds and vibration while driv-
ing and during shifting.
9. CLIMBING CONTROL FUNCTION
 Check that the gear remains in 3rd when going
up a grade.
 Check that the gear remains in 3rd when apply-
ing the brakes while going down a grade.
10.TRANSFER CLUTCH
Check tight corner braking when the vehicle started
with steering fully turned.
11.OIL LEAKS
After the driving test, inspect for oil leaks.

Transfer Clutch
12) Install the transfer clutch assembly without
damaging seal ring.
E: INSPECTION
 Inspect the drive plate facing for wear and dam-
age.
 Inspect the snap ring for wear; return spring for
permanent distortion, breakage and deformation.
 Inspect the damage for D-ring.
 Measure the extension end play and adjust it to
within specifications. MENT, Transfer Clutch.>
1) Check clearance between snap ring and pres-
sure plate.
2) Before measuring clearance, place the same
thickness of shim on both sides to prevent pressure
plate from tilting.
3) If the clearance is out of specification, select a
suitable retaining plate and adjust it.
Standard value:
0.7 — 1.1 mm (0.028 — 0.043 in)
Service limit:
1.6 mm (0.063 in)4) Check that the tight corner braking does not oc-
cur when the vehicle is started with steering wheel
held at fully turned position. If tight corner braking
occurs, perform the following procedures.
(1) With the steering wheel held at fully turned
position, drive the vehicle in “D” range and with
vehicle speed at approx. 5 km/h (3 MPH) in both
clockwise and counterclockwise directions for
approx. ten times each, while repeating acceler-
ation and braking intermittently.
(2) If the tight corner braking still persists, drive
the vehicle again in a circle for several laps.
F: ADJUSTMENT
1) Measure distance “A” from end of extension
case and rear drive shaft with ST.

2) Measure the distance “B” from the transmission
case end to reduction drive gear end surface with
ST1 and ST2.
