For those w/ CVTs, if you're keeping your cars long term, it's advised to change the CVT fluid every 30-40k kms. Driving short distances & in heavy traffic are classified under severe conditions usage. Passing on here the parts & procedure needed for '14-'18 XT CVT as shared in subaruforester.org by member, 1roamingnome:
Parts:
-Transmission pan filter
-5gal bucket of Subaru High Torque CVT Fluid
-Transmission drain plug crush washer
-Transmission fill plug gasket
-Permatex RTV, preferably its quick cure "The Right Stuff"

Basic Procedure : Vehicle must be perfectly level.
1) Drain fluid, meaure volume, observe color & smell.
2) Remove fill plug at rear end of transmission case (allen plug).
3) Drop pan, replace pan screen,. Clean magnet& pan well. Remove all original Subaru orange Gasket Maker (rtv). Use wipes that won’t leave any lint behind. That pan should have nothing in it when done, just the clean magnet.
4) Should brake cleaner be used, None should hit the valve body nor the CVT. Just use it on a pc of cloth to remove oil and debris from mating surface.
5) Clean mating surfaces of the transmission & pan thoroughly. When done, it should be clean shiny metal .
6) Apply Permatex " The Right Stuff " to the transmission pan. Follow directions. It cures fast and the equipment can be returned to service immediately.
7) With an extra pair of hands holding the pan up, mate it to the bottom of the transmission. Before mating, wipe clean any oil from mating surfaces Finger tighten bolts, corners 1st.
8) Install remaining ones by hand. Then, lightly torque in cris-cross pattern.
9) Lightly torque is super important....steel going into aluminum.
10) Replace transmission pan drain plug w/ new crush washer.
11) Fill transmission through fill plug in rear of transmission. Fill with High Torque CVT Fluid using a new pump. Do not contaminate CVT and Fluid with anything foreign.
12) Fill til fluid drips out fill port. Reinstall drain plug with original gasket, then, lightly tighten.
13) Start engine and idle til transmission fluid temp comes to between 35°C-45°C. Use a vehicle diagnostic computer that can access tranny temp out of the OBD or TCM.
14) Run the gear selector through the gears. R N D then D N R P. This ensures fluid is well circulated.
15) With engine running and transmission in park remove fill plug. Add CVT fluid til it drips out the fill plug. When it’s at a slow drip to no drip reinstall fill plug. Remove old gasket and use new gasket.Torque to light tight, torque spec 35 ft/lbs.
16) Clean everything up, clean off any splashed cvt fluid on transmission and exhaust.
17) Check for leaks and weeps. Tighten transmission pan drain plug if its leaking or weeping till leak/weep stops.
18) Now you are going to need an advanced diagnostic computer. Most of us will have to go to the dealership to access the TCM for a relearn procedure. The procedure takes about 20 mins though and will have to be done with the transmission fluid temp around that 40°C.
19) Drive lightly, no WOT, nor quick acceleration for 100kms let the transmission relearn itself out with the new fluid.

That's CVT maintenance for everyone....pro or anti.[emoji4][emoji13]

that panscreen is needed maybe after 5years.. its not like an oil filter. its a sealed trans after all.

But while one is at it, why not swap it in 1 go? The thing w/ CVTs is we gotta keep its own bits from killing itself by regular fluid changes as they're practically non-rebuildable. They're efficient, yes, but, however one sugarcoats, spins or defends em, CVTs can never claim durability the way they're currently built. Sad truth, apologies.[emoji852]
