Subaru Outback: Road Test

A: INSPECTION

1. GENERAL PRECAUTION

Road tests should be conducted to properly diagnose the condition of 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 ←→ 5th while driving on normal city streets.

3. D RANGE SHIFT SHOCK

Check the shock level when shifting up during normal driving.

4. KICK-DOWN FUNCTION

Check kick-down for each gear. Check the shock level during kick-down at the same time.

5. ENGINE BRAKE OPERATION

6. LOCK-UP FUNCTION

When the accelerator is lightly depressed while driving on a flat road in lock-up range, check that rpm does not change abruptly.

7. P RANGE OPERATION

Stop the vehicle on an uphill grade of 5% or more and shift to the "P" range. Check that the vehicle does not move when the parking brake is released.

8. NOISE AND VIBRATION

Check for noise and vibration while driving and during shifting.

9. OIL LEAKAGE

After the driving test, inspect for oil leaks from the transmission body.

Stall Test

A: INSPECTION

NOTE: The stall test is extremely important in diagnosing the condition of an automatic transmission and engine.

The test is necessary to measure the engine stall speeds in "2nd gear of manual mode".

Purposes of the stall test:

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 correct.

6) Raise the ATF temperature to 70 to 80ºC (158 to 176ºF) 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)-18, Read Current Data.>

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 properly, then set to "2nd gear of manual mode".

9) While stepping hard on the brake pedal, gradually 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 one minute or more.

NOTE:

Stall speed (at sea level): 2,100 - 2,600 rpm

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 before shock is felt. Using this, check the condition of forward brake, reverse brake, 1st one-way clutch and 3rd one-way clutch.

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 Standard: 1.2 seconds or less

If "N" → "D" time-lag is longer than specification:

4) In the same manner, measure the time lag of "N" → "R".

Time-lag Standard: 1.5 seconds or less

If "N" → "R" time lag is longer than specification:

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 pressure.

1) Lift up the vehicle.

2) Remove the test plug and install the ST.

ST 498897200 OIL PRESSURE ADAPTER

3) Set the ST1 and ST2.

ST1 498897200 OIL PRESSURE ADAPTER
ST2 498575400 OIL PRESSURE GAUGE ASSY

4) Lower the vehicle, and pull ST2, which were set in step 3), into the vehicle.

5) Connect the Subaru Select Monitor to the data link connector and read the current data. <Ref. to 5AT(diag)- 18, Read Current Data.>

6) Perform line pressure test in the same manner as the stall test.

NOTE:

7) Remove the ST and install the test plug.

NOTE: Use new O-rings.

Tightening torque: 13 N*m (1.3 kgf-m, 9.6 ft-lb)

Transfer Clutch Pressure Test

A: INSPECTION

1) Lift up the vehicle.

2) Remove the bolts holding the heat shield cover, and move the heat shield cover to the rear.

3) Remove the test plug and install the ST.

CAUTION: Be careful not to cut yourself on the heat shield cover when removing the test plugs and setting the ST.

6) Connect the Subaru Select Monitor to the data link connector and read the current data. <Ref. to 5AT(diag)- 18, Read Current Data.>

7) Perform the transfer clutch pressure test in the same manner as the line pressure test.

NOTE:

 Clutch Fluid

A: INSPECTION 1) Park the vehicle on a level surface. 2) Check the clutch fluid level using the scale on the outside of the reservoir tank. If the clutch fluid level is below "MIN", fill the clutch fluid up to "MAX" level, and make sure that there is no leakage. MAX. level MIN. level Reservoir

 Driving tips

● On a road surface where there is a risk of wheelspin (for example, a snow- or gravel-covered road), you can pull away from a standstill safely and easily by first selecting the 2nd gear of the manual mode. ● Always apply the foot or parking brake when the vehicle is stopped in the
