How do you change the transmission fluid on a Subaru Outback 2.5L?

Answer 1

If you're changing the fluid in an automatic transmission, you'll have to remove the entire pan which is kind of messy so be prepared! It'll be held in place by about a dozen bolts. I usually loosen all of them a half turn and then slowly drop the pan lower in the rear so the fluid can pour out away from my head and into a catch can.

You may want to invest in a "tranny filter kit" which has a new pan gasket and filter. And keep in mind that depending on the model year of your suby, the filter can be to the side of the transmission instead of on the inside (sneaky).

If your kit came with a rubber gasket, which they usually do, don't put gasket sealer on it when you put it back together or it will seriously leak.

Your Suby Dealer can tell you what kind of fluid to put into the tranny (via the dipstick tube) and how much.

Good luck!
