Fluid capacity:
Fill the same amount of fluid drained from drain plug hole.
8) Bleed the air from control valve.
9) Check the level of ATF.
10) Perform the advance operation of learning control.
Turbo-model
(1) Warm up the automatic transmission. (Raise the ATF temperature to 60 - 90°C (140 - 194°F).)
(2) Set the select lever to "P" range and apply parking brake, then lift-up the vehicle.
(3) Connect the SUBARU Select Monitor to vehicle.
(4) Using SUBARU Select Monitor, check that the DTC is not output.
(5) Using SUBARU Select Monitor, select the {2. Each System Check}~{Transmission Control System}~{Current Data Display & Save}~{12. Data Display}, and then indicate ATF Temp. data with using the scroll key.
(6) Using SUBARU Select Monitor, verify the ATF temperature is within a range of 60- 90°C (140 - 1 940 F). During operation of the advance operation of learning control, leave the indication of SUBARU Select Monitor display as it is.
(7) Take all electrical load (headlight, air conditioner, seat heater, rear defogger, etc.) off the vehicle.
(8) With pressing shift lock release button, set the select lever to "R" range.
(9) Leave the vehicle for 30 seconds as it is.
(10) lf error message "Communicate Failure" is indicated on the display of SUBARU Select Monitor, turn the ignition switch to ON with depressing the brake pedal. (Keep the brake pedal depressed after this step.)
(11) Confirm that display of SUBARU Select Monitor return to normal indication. (the error message is not shown.)
(12) Set the select lever to "P" range, and then wait for more than three seconds.
(13) Set the select lever to "R" range, and then wait for more than three seconds.
