Thread '2024 Subaru Outback XT first gear oil change front and back. - Notes'

Today I did the drain and fill on the front and back.
These are for the XT model the non-XT is very slightly different (tools needed drain plug placement etc)

Car was at 29600 miles, 2 years 2 months old.

Make sure you do the front diff and the transfer case. They have more issues with front then the rear

@Jerrysends only use approved fluid in the TC. And do the TC reset. Don't listen to anyone on a forum that says it isn't necessary. It won't relearn on it's own. BMW put the reset in the procedure for a reason and those guys on the forum aren't engineers from BMW. If you don't have a scanner that will do the basic BMW resets, you need one.
