Pull dipstick, read it, (and manual) for directions. Check level. Use long funnel to fit into dip stick tube. Fill as needed.

You don't have an automatic in a 2017. You have a CVT. No dipstick. Why do you think you need to add fluid?

This was common during the 4EAT days when people would drain the ATF and the refill the still full engine with 4 more quarts of oil. Eventually Subaru changed the transmission drain plug from a 17mm bolt head to a T70 Torx bit. Looks like they need to do that again with the CVT

I tried topping off the high torque CVT last year with no luck.

You're supposed to open the crank case and fill to the top line.

A factory manual is available here.
Thank you! Do you happen to know if it's the same for 2017 outback? I see the same plug on my car but it seems rather low to the pan and I am curious how all the fluid that came out would go back in?? I carefully measured all that got drained and it came to 4.5 quarts. Does this seem correct?

Thanks again!

It's the same 2015-2019 to the best of my knowledge.

There is more in the cooling system and the torque converter but you will likely not get that out without some heroic flushing techniques.

Just by pulling the drain plug you will usually get 4.5 quarts.

There is a different plug, higher up on the CVT, where you refill until the fluid comes out of that plug hole.

An often missed part of the transmission drain/fill procedure is an overflow line that will release about 8cc in to a different area (the bell housing) and you can drain that after you have topped off the CVT.
--------------------
This is a pretty thorough Youtube process of draining (flushing) and refilling the CVT. The only thing he missed was to drop the transmission pan and replace the sump filter and pan gasket.
