How do you change the automatic transmission fluid in a 2005 outback?

Answer 1

Approx 30,000 miles.

Instructions: There is a #70 torx bolt in the transmission to drain the fluid. You will need to purchase a new transmission bolt washer from the dealer before removing the bolt. Place a drain pan under the car and remove the bolt. Drain the fluid, replace the washer on the drain bolt, clean the drain bolt, reinstall the the drain bolt and fill with the same amount of Subaru transmission fluid that you drained. This should be around 3.5 to 4 quarts. If the Transmission Fluid has not been changed for a long time, drive the car and then repeat this process two more times. This is to change fluid trapped in the transmission. Not all of the fluid comes out each time the transmission is drained.

On some models the filter is on the side of the transmission and can be spun off and changed. on other models it is internal. The manual states internal filter does not need to be changed.
