Subaru Outback (BR): Differential Gear Oil in Continuously Variable Transmission

A: INSPECTION

Check that there is no leakage of differential gear oil from the converter case.

B: ADJUSTMENT

NOTE: Immediately after removing the overflow drain plug, remaining gear oil (approx. 8 cc) may come out of the overflow pipe. This is not included in the specified amount. When removing the overflow drain plug, make sure the gear oil flows out of the overflow drain plug hole by filling with gear oil.

1) Remove the air breather cap.

2) Lift up the vehicle.

3) Remove the overflow drain plug.

1. Overflow drain plug

4) Fill in the differential gear oil through the charge pipe up to where the oil flows out of the overflow drain plug.

Recommended gear oil: <Ref. to CVT-5, RECOMMENDED GEAR OIL, SPECIFICATION, General Description.>

5) When the flow of the differential gear oil turns into a narrow stream, install the overflow drain plug.

NOTE: Use a new gasket.

Tightening torque: 35 N*m (3.6 kgf-m, 25.8 ft-lb)

6) Install the air breather cap.

C: REPLACEMENT

CAUTION:

• Immediately after the vehicle has been running or after idling for a long time, the differential gear oil will be hot. Be careful not to burn yourself.
• Be careful not to spill differential gear oil on the exhaust pipe to prevent it from emitting smoke or causing a fire. If gear oil adheres, wipe it off completely.

1) Lift up the vehicle.

2) Remove the differential gear oil drain plug using TORX bit T70. Drain differential gear oil.

3) Install the differential gear oil drain plug using TORX bit T70.

NOTE: Use a new gasket.

Tightening torque: 70 N*m (7.1 kgf-m, 51.6 ft-lb)

1. Differential gear oil drain plug

4) Pour gear oil from the charge pipe.

Recommended gear oil: <Ref. to CVT-5, RECOMMENDED GEAR OIL, SPECIFICATION, General Description.>

Gear oil capacity: <Ref. to CVT-5, RECOMMENDED GEAR OIL, SPECIFICATION, General Description.>

5) Adjust the level of differential gear oil. <Ref. to CVT-41, ADJUSTMENT, Differential Gear Oil.>

Variator Chain Break-in

A: GENERAL DESCRIPTION

Perform Variator Chain Break-in when the following work has been performed.

• Variator chain replacement
• Primary pulley and secondary pulley replacement

B: PROCEDURE

NOTE:

• During variator chain break-in, VDC warning light and EPB warning light illuminate because of the difference between the vehicle speed value and G sensor value. This is not the malfunction. If the warning light illuminates, clear the VDC and EPB memory after the variator chain break-in is finished. <Ref. to VDC(diag)- 25, Clear Memory Mode.> <Ref. to PB(diag)-25, Clear Memory Mode.>
• During variator chain break-in, if the above malfunction code is detected, fail mode is entered. If this happens, symptom such as engine speed rapid increase occurs, even when the accelerator pedal is depressed gradually.

1) Lift up the vehicle.

CAUTION: Lift up the vehicle until the tire bottom is 0.3 m (0.98 ft) or more above the ground.

2) Shift the select lever to "P" or "N" range.

3) Apply the electronic parking brake.

4) Connect the Subaru Select Monitor to data link connector.

5) Idle the engine to raise the CVTF temperature to 40 - 50ºC (104 - 122ºF) displayed on the Subaru Select Monitor.

NOTE: When CVTF temperature does not rise easily or if you want to rise CVTF temperature faster, maintain the engine speed within 2,000 - 2,500 rpm at "P" or "N" range to raise the CVTF temperature.

6) With the select lever in "P" or "N" range, increase the engine speed to 3,000 - 3,500 rpm from the idling condition, and maintain the speed for approximately five seconds, then release the accelerator pedal.

7) Depress the accelerator pedal gradually again from idling condition to increase the engine speed to 3,000 - 3,500 rpm, maintain the speed for approximately five seconds, then release the accelerator pedal.

8) Release the electronic parking brake.

9) Shift the select lever into manual mode and set to 1st.

10) Depress the accelerator pedal gradually, and increase the engine speed to 5,300 rpm from engine idling condition.

NOTE: Increase the engine speed while taking care that the engine speed does not become too high.

11) Release the accelerator pedal to fully closed position to lower the engine speed to 4,000 rpm.

12) Depress the accelerator pedal gradually again, and increase the engine speed to 5,300 rpm.

13) Repeat the step 11) and 12) for 40 times.

14) Release the accelerator pedal to return the engine speed to idling.

15) Shift the select lever to "P" range, and then turn the engine to OFF.

AWD ON/OFF Switching Mode

A: GENERAL DESCRIPTION

• Follow the messages displayed on the Subaru Select Monitor when working.
• Perform as necessary in FWD mode.
• When switched to FWD, AWD light illuminates.

B: PROCEDURE

CAUTION:

• Do not turn the power of the Subaru Select Monitor OFF during work, and do not disconnect the data link connector.
• On completing the work in FWD, switch back in AWD.

1) Shift the select lever to "P" range.

2) Connect the Subaru Select Monitor to data link connector.

3) Turn the ignition switch to ON. (In the case of a push button start, press the push button ignition switch twice without stepping on the brake) 4) Turn off all switches causing an electrical load, such as headlights, A/C, seat heater and rear defogger.

5) Select {AT related learning & inspecting mode} in the "Transmission Diagnosis" screen of the Subaru Select Monitor.

6) Select {AWD ON/OFF switching mode} in the "Learning and inspection mode related to AT" display screen of the Subaru Select Monitor.

7) Follow the messages displayed on the Subaru Select Monitor screen when working.

Switching completes successfully if any of the following messages is displayed.

• When switching from AWD to FWD: {Switched to FF. To return to AWD, perform basic mode again.}
• When switching from FWD to AWD: {Switched to AWD. To return to FF, perform basic mode again.}

NOTE:

• If communication error occurs during switching mode, start in the "AWD ON/OFF switching mode" again.
• If operation is interrupted before the successful end message is displayed, perform the {AWD ON/OFF switching mode} from the beginning until confirming the operation is successfully ended. If this mode fails to complete successfully, the cause is as follows.
  • Select lever is not in "P" range.
  • Engine is running.
• For details concerning the operation procedure, refer to "PC application help for Subaru Select Monitor".
