You will need 7qts of fluid if you are doing the filter also.

Hi mate! I am from Kazakhstan and I owned this car last year. I can't find original and Amsoil here in Kazakhstan. Could you please check the characteristics of Shell Spirax S5x? Is it compatible for Ascents?

@danielpacheco8650 says:

Hey man great video. Dealer try and charge me $400. Ill do myself

@m.a.omarkhail8294 says:

Hey @BuiltForSpeed the dealership told me that the Transmission should be 40 degrees Celsius. Is that true?

Hi bro, I want to do my own CVT change on my 3.6 outback TR690 transmission. Subaru recommends CVTF-II high torque fluid. Is this Amsoil CVT fluid ok to use? I checked their website and it didn't mention it is a high torque or CVTF-II, are you sure this fluid is ok to use?

@georgestephenson356 says:

This seems like a partial CVT fluid change. The Ascent CVT holds around 13 qts, right? This guy did a PARTIAL change of fluid. To change completely you need to flush it with fluid, then refill it with pressurizing pump, or while running.

@dyu18 says:

Is this fluid compatible for the subaru outback 3.6r ?

@hansgiger4183 says:

To much bullshit blah blah talking, nothing technicall information

@Life2race says:

Surprisingly if you look at the. Subaru book that came with car In fine print says change fluid at 27k or 3 yrs

@Marco-qe5zw says:

CVTs dont have gears… great video, thanks!

im also curious to see the color of the Amsoil after 30k

@Ryan-kk2rr says:

How's she running since the change? I just hit 30k and was thinking of going with Amsoil based on your video.

@alycorleto says:

Good video but you did not show where you added the cvt fluid Very important.

@nathanbrowning712 says:

Extremely helpful video. Thanks man!

Once warranty runs out I’m going Amzoil

@chrisryan8863 says:

I love Amsoil and use it in all my cars except ones that are under warranty and the manufacturer "requires" use of their ATF fluid. If the tranmission had an issue they will void the warranty if you don't use their fluid. "Mr. Subaru" on Youtube is a Subaru tech and he called Subaru of America and was told directly two things that I think are ridiculous: 1. The CVT transmission is a supposed "lifetime" service unit, meaning no fluid change is "required" and any draining or opening up the system at all voids warranty (I think this is crazy but that is apparently something to consider if the car is still warrantied), 2. If the transmission had to be serviced for a problem the tech has to use their fluid. Anyway, I am just sharing this so you and the channel followers are aware of this. I think the idea of "lifetime" fluid is nuts, but if my car was still warrantied I would be careful to drain it.

@somebody3398 says:

Changed the CVT fluid on my 2020 Subaru Forester and I ended using 6 quarts of CVT fluid, which was juuuuust enough. To air on the side of caution I would suggest 7 quarts, but if you are confident you are not going to spill too much fluid during the change then 6 quarts will do. This is without changing the filter and dropping the pan. Just a drain and a refill.
