Hi , Thanks for all the pictures. I have a 2015 forester2.5i also. I believe the info.
on your second thumbnail is incorrect. The fill plug for the CVT is located higher than the plug that you show. If I remember correctly the fill plug is on the same side as you show but its about 3-4 " higher. I know this because a couple months ago I mistakenly drained the CVT trans ,thinking it was the engine oil drain,never make that mistake twice. Anyway not sure about any of the other illustrations. ed

 

Is there an unlabeled CVT overflow plug somewhere?

As in you fill at the fill hole until it comes out the overflow hole?

I have the MT so I can't look at mine but might be useful for other people

 

IMHO, the Rear Diff Fill and Drain photos are correctly labeled.

The Oil Drain photo is correctly labeled.

I can't speak for the Front Diff or CVT photos.

Thanks for posting the photos. Hopefully someone can correctly identify the Front Diff and CVT.

Please update the photos once the locations have been confirmed.

 

I have just added official diagram for CVT Refill plug and Front Diff Drain (star shape plug) and Overflow (level) plug location.

Comparing digram with photos will clarify the locations.

Hope it helps.

 

Creavation, thank you for this thread and for taking the time to post the photos and diagrams.

I am really hoping that with time, members can help with expending on this with more details concerning "how to" replace these fluids so that when we tackle these projects for the first time, we can make sure to have all the right tools (socket sizes/ types, extensions, funnels, fluid pumps, type and amount of fluid etc) so that we don't get stuck in the middle causing hours of delay running around with a second car to pick up the missing needed item.

For me, the front diff on the cvt looks especially unique.

Usually, there is only one filler/ level plug towards the top. One removes the cover which dumps the fluid, replaceces the cover, and adds fluids to the only fill plug towards the top until it starts to drip out. Close the plug and done.

The rear diff looks even easier considering that it has one plug for dumping the old fluid and one to fill/ level check and no need to mess with the diff cover gasket.

This front diff on the cvt, however, has three plugs that need to be removed. Especially odd, but kinda cool once it's understood, is the level check that has the opening towards that bottom (same as the drain plug). I can only imagine that there is some type of chamber in the diff housing that only sends fluid there once it reaches a certain level.

A unique chamber is likely also built into the housing to fill these front diffs.

Definitely more complicated than the standard simple diffs designs that I usually see, but mostly from an enginearring standpoint. It shouldn't be too bad to change fluids once we know what tools and supplies are required/ recommended for the do it your selfers.

Also, too bad we don't have a dip stick on the cvt. For th past 10 years I have changed out the transmission fluids in all of my cars and most family members cars.

This no dip stick thing and having to have the cvt up to a certain temp is probably going to force me into the dealership for this service for the first time in over a decade.

One could probably measure the amount of fluid that goes out and fill with the same amount, but what if it was a bit low to begin with for some reason? No dip stick is not ideal imo.

Again, thanks very much for this thread and I really hope that it gets expended on concerning the specific tools needs and maybe some tips.

Happy New Year!

 

Shora; I did a re-fill article on the 2015 2.5i CVT trans.It is from
9/11/14 and is titled Re filling the 2015 2.5i CVT Trans. You may want to read it to familiarize yourself with the procedure. ed

 

front diff fill plug

hello, how hard was it for you to remove the front diff fill plug? so far i have broken two extension bits trying to get it off and i am literally moving the engine while i am trying to get it off. this is the first fluid change for the front diff if that is helpful.

 

Hi all, I might have slightly damaged the front differential overflow plug (8mm Hex) and the front differential drain plug (T70 Torx), and I am worried if I don't replace it during the next few fluid changes I might strip it and can't take it out. I tried very hard to find the part number on service manual or Subaru website, but cannot find them to save my life. Do you guys know or know where to find the part #? Much appreciated for your help !
