8) Add fluid through the refill hole until the fluid flows out of the overflow tube.[*6]
CAUTION:

• Use auto-fluid WS.

• Slowly add the fluid. Adding the fluid rapidly can cause the fluid to hit internal parts and splash

around resulting in fluid flowing out of the refill hole.

9) Wait until the fluid stops flowing and is only dripping.[*7]

10) Temporarily tighten the overflow plug using a 5-mm (0.2 in) socket hexagon wrench and a new gasket.[*8]

11) Add fluid through the refill hole until reaching the specified amount when removing/installing the oil

pan.[*9]
NOTE:

If fluid flows out from the refill hole and you cannot fill the specified amount when adding fluid through the refill

hole, perform procedures [*10] to [*15] below in order to circulate fluid until it reaches the oil passages in the

transmission and inside the torque converter, then add the specified amount of fluid through the refill hole.
Filling amount (reference):

2.0 L (2.1 US qt, 1.8 Imp qt)

12) Temporarily tighten the refill plug using an O-ring.[*10]

13) Lower the vehicle.[*11]

14) Start the engine.[*12]
NOTE:

Start the engine with the air conditioning turned off.

15) Slowly move the shift lever from the P to M position, and shift again to the P position.[*13]

16) Idle the engine for 30 seconds to warm up the engine.[*14]

17) Turn the key to IG OFF.[*15]

18) Repeat procedures from [*1] to [*15].

19) Repeat procedures from [*1] to [*2].

20) Perform final tightening of the drain plug using a new gasket.
Tightening torque:

20 N·m (2.1 kgf-m, 7.4 ft-lb)

21) Repeat procedures from [*4] to [*11].

22) Adjust the fluid amount. <Ref. to PM-72, AUTOMATIC TRANSMISSION FLUID AMOUNT ADJUST-

MENT, ADJUSTMENT, Automatic Transmission Fluid.>

23) Install engine under cover No. 2.

24) Install engine under cover No. 1.

25) Lower the vehicle.

26) Procedures finished.

C: ADJUSTMENT

NOTE:

• Use auto-fluid WS for the filling fluid.

• Be sure to always park the vehicle on a level surface when adjusting the fluid amount.

• If it is necessary to replace the automatic transmission assembly, remove/install the oil pan and drain plug,

and fill with a large amount of fluid for replacement, perform the procedures from “Automatic transmission flu-

id filling” to “Automatic transmission fluid amount adjustment”.

• If a small amount of fluid filling is necessary for repairs such as replacing the extension housing rear oil

seal or oil bleeding, perform only the procedure “Automatic transmission fluid amount adjustment”.

Fluid refill and adjustment image:

Initial refill

Overflow tube

Specified
amount

Overflow plug

Fluid temperature adjustment

Refill the oil pan with fluid to a
certain amount.

Specified amount refill

Refill with the specified amount
according to the operation.

Refills to the
extent that the
fluid overflows.

Fluid amount adjustment

Overflow the fluid at the proper temperature for
fluid amount adjustment.

Open the plug to the
extent that the fluid flows
like a thread.

When the fluid does not overflow,
refill with an amount that forces
the fluid to overflow.

While circulating the fluid with the engine start, shift to “oil temperature
detection mode” to obtain the proper temperature for fluid amount
adjustment.

1. AUTOMATIC TRANSMISSION FLUID FILLING

CAUTION:

• Perform procedures when the automatic transmission fluid is sufficiently cool.

• Always be sure to switch to oil amount adjustment mode when filling automatic transmission fluid.

• Slowly add the fluid. Adding the fluid rapidly can cause the fluid to hit internal parts and splash

around resulting in fluid flowing out of the refill hole.

1) Lift up the vehicle and maintain in a horizontal position.

2) Remove engine under cover No. 1.

3) Remove engine under cover No. 2.

4) Remove the refill plug and O-ring.

5) Remove the overflow plug using a socket hexagon wrench.

6) Add fluid through the refill hole until the fluid flows out of the overflow tube.
CAUTION:

Slowly add the fluid. Adding the fluid rapidly can cause the fluid to hit internal parts and splash

around resulting in fluid flowing out of the refill hole.

7) Temporarily tighten the overflow plug.

8) Add the specified amount of fluid through the refill hole and temporarily tighten the refill plug.
Filling amount (reference):

2.0 L (2.1 US qt, 1.8 Imp qt)

NOTE:

If fluid flows out from the refill hole and you cannot fill with the specified amount when adding fluid through

the refill hole, perform the following procedures to circulate fluid until it reaches the oil passages in the trans-

mission and inside the torque converter.

(1) Temporarily tighten the refill plug.

(2) Start the engine.

(3) Slowly move the shift lever from the P to M position, and shift again to the P position.

(4) Idle the engine for approximately 30 sec.

(5) Turn the key to IG OFF.

2. AUTOMATIC TRANSMISSION FLUID AMOUNT ADJUSTMENT

CAUTION:

• Perform procedures when the automatic transmission fluid is sufficiently cool.

• Always be sure to adjust the automatic transmission fluid amount when at the proper temperature

for oil amount inspection.

1) When using Subaru Select Monitor

(1) Connect the Subaru Select Monitor to data link connector.

(2) Turn the ignition to ON. (engine OFF)

(3) Turn off all parts effecting an electrical load such as air conditioner, audio and lights.

(4) Select {Work Support} on the «Transmission Diagnosis» screen of the Subaru Select Monitor. Select

{ATF level adjustment mode} on the «Work Support» screen of the Subaru Select Monitor.

NOTE:

If the temperature is 42°C (107.6°F) or more, leave the vehicle in a cool location and restart procedures after

the ATF temperature has decreased.

(5) Increase the oil temperature by idling the engine while checking the ATF temperature from the Subaru

Select Monitor screen.
