CAUTION

- When performing service operation, refer to “Repair Contents” in “General Description”. REPAIR CONTENTS>Repair Contents

- Prior to starting work, pay special attention to the following:

  1. Always wear work clothes, a work cap, and protective shoes. Additionally, wear a helmet, protective goggles, etc. if necessary.

  2. Protect the vehicle using a seat cover, fender cover, etc.

  3. Prepare the service tools, clean cloth, containers to catch grease and oil, etc.

- Prevent scattering of grease and oil. If it scatters, wipe it off immediately to prevent it from penetrating the floor or flowing out, to protect the environmental.

- If the grease and oil is spilt over the engine, exhaust pipe or the under cover, completely wipe it off to avoid emission of smoke or causing a fire.

- Vehicle components are extremely hot immediately after driving. Be wary of receiving burns from heated parts.

- When performing a repair, identify the cause of trouble and avoid unnecessary work.

- Before disconnecting connectors of sensors or units, be sure to disconnect the ground terminal from the battery sensor.

- Always use the jack-up point when the lifting device, shop jacks or rigid racks are used to support the vehicle.

- Before starting works, remove dirt and corrosion around the target area.

- Keep the removed parts in order and protect them from dust and dirt.

- All removed parts, if to be reused, should be reinstalled in the original positions with attention to the correct directions, etc.

- For the parts except for the non-reusable parts, replace then with new parts if necessary.

- Be sure to tighten bolts and nuts to the specified torque.

- Always use new application oil during work.

- Always remove or install the transmission body in an area where lifting devices, transmission jacks, etc. are available for ready use.

CONTINUOUSLY VARIABLE TRANSMISSION(TR580) > CVTF
INSPECTION

- When inspecting CVTF level, observe the specified CVTF temperature.

- Do not add CVTF at a cold condition since the oil may blow out.

When there is no severe conditions or intrusion of water, etc., replacement of CVTF is unnecessary.

1.

Prepare the CVTF for refiling.

2.

Connect the Subaru Select Monitor.

3.

Turn the ignition switch to ON. (Engine OFF)

4.

Display [ATF Temp.].

5.

Start the engine and raise [ATF Temp.] to 35 — 45°C (95 — 113°F).

Make sure to perform the CVTF level inspection within [ATF Temp.] of 35 — 45°C (95 — 113°F).

6.

Operate the select lever in P→R→N→D and D→N→R→P to circulate CVTF with the engine idling.

7.

With the engine idling, lift up the vehicle and remove the filler plug.

- CVTF is at the specified level when it is up to the filler plug hole lower section.

- Prepare the container for draining of engine oil.

8.

If the CVTF level is below the bottom of the filler plug hole, check for oil leakage, and add specified CVTF.

Always use specified CVTF. Using fluid other than specified CVTF will cause malfunction.

- If the initial load is not within the specified range, select the drive pinion washer, and repeat the step until the initial load is within the specified range.

- When a thicker drive pinion washer is selected, the initial load decreases. When a thinner drive pinion washer is selected, the initial load increases.

Initial load:

5.1 — 17.1 N (0.5 — 1.7 kgf, 1.1 — 3.8 lbf)

Preparation tool:

ST1: ADAPTER (499787500)

ST2: WRENCH (499787700)

ST3: HOLDER (498937110)

Using the following formula, calculate the tightening torque for a torque wrench.

T2 = L2/(L1 + L2) × T1

T1: 170 — 250 N·m (17.3 — 25.5 kgf-m, 125.4 — 184.4 ft-lb) [Specified tightening torque range]

T2: Tightening torque

L1: ST1 length 0.072 m (2.83 in)

L2: Torque wrench length

Example:

Torque wrench length m (in) | Tightening torque N·m (kgf-m, ft-lb)
0.4 (15.75) | 144 — 211 (14.7 — 21.5, 106.2 — 155.6)
0.45 (17.72) | 147 — 215 (15.0 — 21.9, 108.4 — 158.6)
0.5 (19.69) | 149 — 218 (15.2 — 22.2, 109.9 — 160.8)
0.55 (21.65) | 150 — 221 (15.3 — 22.5, 110.6 — 163.0)

Using a dial gauge and a magnet stand, measure the backlash by inserting the dial gauge through the window of differential case.

When measuring, fix the differential bevel pinion in place with a screwdriver covered with cloth, or a similar tool.

Specification:

ST2: WRENCH (499787700)

4.

While rotating the drive pinion, tighten the LH differential side retainer and loosen the RH side until it does not rotate anymore. The backlash is “zero” when the drive pinion comes to the point where it doesn’t rotate.

5.

After reaching the “zero” state, loosen the LH differential side retainer by 3 notches and secure it with the lock plate. Retighten until the RH differential side retainer stops. Rotate the drive pinion 2 or 3 times. Tighten the RH differential side retainer further 1-3/4 notches. This sets the preload. Finally, secure the differential side retainer with the lock plate.

Turning the differential side retainer by one notch (A) changes the backlash approx. 0.05 mm (0.0020 in).

Insert the ST (Axle Shaft) into the right and left sides of differential case.

The ST (Axle Shaft) is a SUBARU genuine part.

CONTINUOUSLY VARIABLE TRANSMISSION(TR580) > AT learning
PROCEDURE

- When replacement of TCM/replacement or disassembly of transmission body/replacement of control valve body/clearing AT leaning value is executed, perform AT learning mode.

- Do not turn the power of the Subaru Select Monitor OFF during work, and do not disconnect the data link connector.

1. PREPARATION FOR LEARNING
1.

Warm up or cool down until [ATF Temp.] displayed on the Subaru Select Monitor is 40 — 65°C (104 — 149°F).

2.

After stopping the vehicle, shift the select lever to “P range”.

3.

Apply the parking brake.

4.

Lift up the vehicle.

While working, be sure to keep the lower edge of the tires 0.3 m (0.98 ft) or more above the ground as vehicle will vibrate.

5.

Connect the Subaru Select Monitor.

6.

Turn the ignition switch to ON.

7.

Turn off all systems causing an electrical load, such as headlights, A/C, seat heater and rear defogger, etc.

2. CLEAR AT LEARNING VALUE

Be sure to perform the AT learning mode after performing Clear AT learning value.

1.

On [Start] screen, select [Diagnosis].

2.

On [Vehicle selection] screen, enter vehicle information and select [Set].

3.

On [Main Menu] screen, select [Each System].

4.

On [Select System] screen, select [Transmission Control System].

5.

On [Select Function] screen, select [Work Support].

6.

On [Work Support] screen, select [Clear AT learning value].

7.

Follow the messages displayed on the screen when working.

8.

When [Clear completed. Turn off the ignition switch. Execute AT learning again.] is displayed, Clear AT learning value is completed.

3. AT LEARNING MODE

AT learning mode is performed with the vehicle lifted, without actually running the vehicle.

1.

On [Start] screen, select [Diagnosis].

2.

On [Vehicle selection] screen, enter vehicle information and select [Set].

3.

On [Main Menu] screen, select [Each System].

4.

On [Select System] screen, select [Transmission Control System].

5.

On [Select Function] screen, select [Work Support].

6.

On [Work Support] screen, select [AT learning mode].

7.

Follow the messages displayed on the screen when working.

8.

When [AT learning normally ended.] is displayed, AT learning mode is completed.

- If communication error occurs during learning, retry the “AT learning mode” from the beginning.

- If the message [Execute AT learning again after fixing troubles of the vehicle] is displayed during learning, select [OK] to display the List of Diagnostics Trouble Code. After repairing the locations indicated by the DTC, start the “AT learning mode” over from the beginning.

- When communication error occurs during learning, select lever does not shift occasionally. If select lever does not shift, turn the ignition switch to OFF before operating the select lever.

- If the message [AT learning ended abnormally. Try again from the beginning.] is displayed, start the “AT learning mode” over from the beginning.

  Display | Main causes for abnormal termination
  [AT learning ended abnormally. Try again from the beginning.] | Fault is detected during AT learning. The accelerator pedal is depressed during AT learning. An unspecified operation was performed during AT learning ATF temperature becomes out of specification during AT learning. Battery voltage is low. The malfunction indicator light is lit. Parking brake is not applied hard enough. Brake pedal is not fully depressed. Abnormal idle speed increase, etc.
