Default CVT Help

Can someone point me in the right direction of how to change the transmission fluid on a 2016 CVT WRX.

Is this something that can be done at home or is this a take it to a shop job?

I also donít know the fluid capacity of the transmission.


Thanks in advance

You drain it, then you fill it, then you bring it up to a specified temperature range, then you either add or remove fluid while it is running.

I have been looking for CVT ATF High Torque, and all Iím finding is 5 gallon containers. Is this not available in quarts?

Doesn't look like it - Amsoil spec only shows it compatible with the regular CVTF (green/blue).
Subaru High Torque is orange. Sometimes you have to pay to play. Maybe you should make friends at the dealer parts department so you can get them to sell you a couple quarts in a Mason or Mayo jar.
When dealer techs perform a drain-n-fill they use 4 to 6 quarts. when they replace a reman CVT they may need a quart or so. They usually just pump it out of the 5 gallon pail. There is a billing part number they use for invoicing quarts on repair orders so the issue is whether they want to go through the hassle of selling it to you.

How much would a flush or CVT service cost on average?

You'd have to call a dealer - every dealer has their own pricing. Sometimes they are bundled. Dealer I worked at used to have a service where we would drain and fill the front differential, rear differential, and ATF/CVT pan. for $275 - $350 depending on which trans you had.

Keep in mind you only get 1/3 to 1/2 the fluid if you drain the pan. The rest is in the torque converter. I know the dealer I worked at only had a flush machine for older "Dexron" type ATF, and would not invest in machines for CVT. Subaru uses 3 different types of CVT fluids that can't be mixed.

How would one determine the correct CVT fluid to use? By VIN? By transmission number? I've got a 13 Crosstrek with a replaced CVT by the dealer under warranty. I've put on about 55k miles and would consider doing a "partial change" as in drain and fill the identical amount by measuring. But if there's any chance I don't have the right fluid....I'm doing nothing.

It is more or less model specific. You have a GEN II CVT - blue or green color. The two are interchangeble. Use Subaru CVTF-II.

I wouldn't do a thing. If that replacement transmission was going to fail it would have by now. That CVT fluid is pretty robust unless there is a catastrophic failure. I have drained many Gen-I and Gen-II CVTs at 180,000+ miles and the fluid is still clear, plenty of color, fresh smelling, just a tad bit darker.

CVT transmissions do not have a bunch of clutch discs in it that wear and contaminated the fluid so it does not get "dirty" like old 4EAT/5EAT/5AT. That is why Subaru "officially" has no service interval for CVT.

1st of all... the 2015+ WRX CVTs have an extended 10yr warranty.

Unless you already have a basis for forfeiting that warranty, either do the service at an 100% "authorized dealer" or do no service at all.

Do you have a leak or any reason to suspect your fluid (or transmission) is in trouble?
Dealers should service leaks and and any CVT-related issue under the extended warranty. After 2 or 3 leaks they may choose to replace your entire transmission.

The gen 2 CVTs have a set of clutches that can wear.
They do recommend a fluid interval if you're towing.

And the fleet purchasing industry looks at maintenance intervals to calculate cost of ownership when deciding what vehicles to buy. The more things you can leave off the list, the better your vehicles look to a fleet buyer (think rental cars, taxis, etc). PCV valves, brake flushes, transmission services, coolant, spark plugs - all pushed out to or past 100k miles...

The high torque fluid comes in 5 gallon buckets - if you want some, for some reason, bring empty quart/gallon jugs and have them fill them up for you. The stuff is stupid expensive.

Yes, but with the exception of the transfer clutch none of the other clutches are used to change gear ratios. Even the lock-up clutch is fully engaged above 5-7 MPH. God help you if your trying to tow with a '13 Crosstrek CVT...
