Cool!

Very nice and thank you!
1. Where did you get the 13 mm socket?
2. My OB doesn't have a dipstick for the CVT. How can i check the level? Or just try to fill until it overflows on the fill plug?

Manual says total capacity is 12.7-13.2 qts, I drained ~6.0 qts and filled with ~5.5qts.

Reference Pictures:

so that means that you didn't change but less than half of the fluid ... Maybe better to leave it to the dealer to get the Subaru fluid and either change it all or leave it alone? Aren't you concerned to mix 2 different fluids? Next time you might end up with 3 ... What will they say to me when i go for a warranty repair?
Thank you for sharing everything and the pics are awesome!

Tools Required:

-I used a 1/2" drive ratchet but a 13mm socket is on order.

Is that 13mm square or hex?

Square and got it from harbor Freight.
12 Piece Drain Plug Socket Set

I'd be interested in other mfgs if anybody has a suggestion.

1. Harbor Freight - 12 Piece Drain Plug Socket Set
2. You check it while idling by taking out the fill plug and see if it overflows.

Thanks for the feedback.

The CVT has a torque converter just like any other automatic slushbox. So you can't get all the fluid out unless you do a re-circulation drain. I plan to drain and refill every 30k from this point forward.

No, I'm not really concerned, my car is out of warranty anyway. I realize I maybe heading into undocumented territory. I'd rather change it than let ride for the lifetime of the vehicle which i hope to be >250k miles.

I'm not suggesting you change it. This guide is help others if they do decide to change their own.

Great write up! Looks like we drive about the same.33,000 a year all highway. My wife has 41K on her 2012. Our tires still have 8-9/32nds and brakes look new. Did you have to do anything other than oil and filters @ 67K? It seems to get better with every mile. The engine is smooth as glass and I have been using Amsoil Long Life from 7,500 and that helps. We never used a drop of oil.

Thank you so much and really appreciate it!
The website I found (from this forum, of course) for the 13mm socket is:
Shop Tools - Ultimatetoolco.com
They seem a little pricy though ... I will check out your supplier for sure and Thanks!! again .

Hm, now I am totally confused . I think the rear diff on my 2013 OB, 2.5i, CVT takes a hex head. So do I need 13mm hex or square? Does anyone know?
