You’re such a great resource for the Subaru community. Thank you for these well made and thorough videos!
You’re welcome!
Awesome 2 in a row! You know Subaru's better than SOA as they don't even recognize changing the fluid until 90+ it has to be planned obsolescence to make you trade up or possible issues. JMO Thanks for ALL you do & the education you gave us ALL! Much respect
They want that “low cost of ownership” to show buyers. Never mind the high cost of repair after not performing preventative maintenance!
The sales guy told us that the fluid didn’t need to be changed at all and the owner’s manual reflected that statement. I had my wife take it in over the summer to get it done anyway at 100K. She does no hard driving so hopefully it’s all good.
@@MrSubaru1387after have my local dealer tell me it doesn't need to be changed I found your videos. It was the first time I heard a "lifetime" fluid and something didn't seem right. Did it myself with your help. Thank you!
@joeymartin8722 and then I believe Subaru Japan recommends every 36k. It's so odd
@@zakedwards6128 I go by every 3yr/36k miles drain and refill.
These videos along with the impressive commonality between Subaru models are incredible for those of us that do our own maintenance. Between the weekend subscriptions to Subaru's TIS website and this kind of content, I haven't had to take my crosstrek to any dealer since 2018! Thank you!
You’re welcome!
I have 60k miles on a Outback in Ireland,have asked 4 main dealers about the possibility of changing CVT fluid.None of them want to do it,I am a little nervous of doing it myself as it's our only vehicle.Thanks for great videos
Do it! It's actually easy and just make sure to level the oil on 95-100F and refill on flat. Had a really bad experience with overfilling by other mechs.
Right you know somebody wasnt rushing it if you did it yourself
Bro honestly its easier than doing an oil change.
That was an awesome information session and demonstration, MrSubaru1387. Thank you for this and all your other informative and helpful videos.
Thank You!
If you kept the temp at the correct degree, drained and refilled, then did the PRND and back sequence, would you have to actually use a scan tool or relearn procedure?
One thing I've learned with these fill plugs for the transmission and both the differentials is using the new grip edge hex sockets. Using them, I have yet to worry about stripping the bolt out compared to using the standard style hex bolts. Comes in handy too when techs who worked on them previously tighten the ever living daylights out of them or strip them partially
Just bought one from MAC Tools. "RPRT"
If I could afford it I’d buy you a lift! I’m 71 with 3 Outbacks I do most of my own service so not really up for scurrying around on the ground.
Really like your videos, thanks!
Agree ! I'm only 53 but bad hip, knees and shoulder. I would absolutely love a Lift !! Well I guess I will leave a note for Santa !! Very good videos !!
Hey man I used to work for Subaru in Australia, when the cvt came out, Subaru told us tech that they are sealed unit and not too change fluid. But I don’t believe the fluid does not need to be changed ever.
Just finished this on my 2013 OB 2.5i and it runs super smoooooth now! Excited to take her on the highway tomorrow. Thanks again!
I have a Forester with 170,000 miles, don't know the service history but it's pretty clean. So glad I found your videos so I can start going through things. Let's get mine to 223,000 too!
I've made do with a 10$ fluid pump from harborfreight for years now, around 6 or 7 times on a couple cars. No need to purchase the myvac units for all you at home mechanics 😊
Which of your videos would best help diagnose a failing valve body vs. torque converter vs. CVT? I tried searching but I'm still unclear how to isolate each point of failure.
Thank you again Mr Subaru! I need to look at that fill tool that you use. Sure beats trying to use funnels for difficult fluid fill jobs.
The little soo-bar-oooo. Wow
That was really great:
I have an idea for another episode - how to use the computer to turn off features like stop start tech and begin start up in ‘S’ mode
Waiting on the Ascent cvt video. Replaced the fluid with the dealer back in June. 64k miles no issues. Dealer said fluid was dark. Carfax showed no info on prior owner. Bought it with 33k on it.
Mr. Subaru, thanks for all your work and resources. I hope you can post a short video or something similar to show people just like me where are the safe point to jack up the subaru forester by using flooring jack. I have seen too many videos on UA-cam that couldn't explain this right. Again, thanks for your help and knowledge!
We have a 2015 Forester. Subaru issued us a 100,000 mile warranty on the transmission but told us it would void the warranty if we ever changed the fluid! The dealer kept telling us to change the fluid until I showed them the letter stating NOT to change the fluid! I’ve been extremely uneasy about waiting till 100,000 to change the fluid. I do it every 30,000 on my Hondas.
I saw you use that Mityvac a couple of videos ago and...I got myself one. Great tool, good for a lot of things!
LOL I bought so many tools because of Mr. Subaru
Excellent, you just saved me $300.00. Of course Subaru America will not be happy with me, hence with you ! 😊
Done my valve body yesterday and will be doing that cvt fluid on Sunday morning..i always enjoy watching all of your vids only difference that i use a XTOOL D8..although this video will be very helpful
How important is it to clear the adaptives and learn process? Our 2017 Outback needs a CVT servicing badly and Subaru would never touch it until I recently went up there and mentioned its a shame Subaru of America thinks the fluid is forever which we know there is no such thing. The new service guy said they are scared to touch then when they haven't been touched for a long while as they've had a few not move afterwards LOL.......Sigh 100k on ours and I worry if I dont do the fluid exchange like you just did they are going to hook it up to a machine and blow the internals to bits now that they will all of a sudden service it. But back to the original question it sounds like I'd need a dealer to do the clearing process. Thank You
When I did on my Impreza 2016 the first cvtf change I disconnected the exit circuit to warmer/cooler thing.....
When I start the engine and in the same time put the new fluid in I observed on the exit the old oil come out. At least 2 liter old oil (I believe old oil resting in tourgue converter.
In total I used 13 l of oil . Pan down and change the metalic "filter".
Clean the magnet.
For leveling I use and obd ho can read CVT temp.
In comparison with drain and fill I think I manage to change a much big procentage....
I kindly ask you...why you don't collect the old oil from upper exit hose ? I know you have a good reason but I don't know what is this reason. Thank you. You are an inspiration for me.
Thank you for the clearly displayed procedure. Would this also apply to a 2017 XT CVT with the 2.0 turbo motor?
I just hit 125k on my 2015 Forester and was curious if I can do a CVT service without the learning process since I don't have access to a tablet like a TOPDON?
Subaru manuals do not call for it. Relearn is only needed for
TCM replacement, Disassembly of transmission, CVT replacement, Valve body replacement, or after Clearing AT learning values. Check the subaruforester threads.
Lots of miles on that car! Great video, thanks!!
Thank you again Mr Subaru! I don't miss one of your videos, thank you very much for your excellent contribution 🙌🏻👏🏻
Is flushing a necessary step? Cvt fluids are not cheap.
How much cvt fluid do you generally use when doing a flush and fill? The valve body kit on subarupartsdeals only includes 2 quarts of fluid. Gotta be more than that, right?
Hi, I replaced my Subaru outback 2013 2.5 transmission, but now the car start but don't move, I fill the transmission with oil til it was dripping from the 8 MLM Allen screw, I also found that the transmission oil don't get hotter even when the car is on for a long time (40-60 minutes, ) what you think it can be the problem? And thank you for all your videos they are a great source of knowledge
So when you replace fluid you have to do the AT learning each time you repalce the fluid?
MrSubaru, great video. I have a 2015 Outback that has never had the fluid changed. Can you recommend a DIY scan tool to read the CVT temp?
I love all your videos! I have learned so much from you. I’m hopping you can help me out with a small recommendation. I have a 2016 cross track with 101k on it and I’m getting oil in my radiator. I have been told it’s the dreaded Subaru head gasket issue. What I need is someone reliable in Southern California area that can do the job. Of course I don’t trust the dealers and they are the biggest crooks out there right up with car sales people. lol. But yes someone please! Thx.
Thank you for all that you do! It would be awesome to see you actually enjoying the cars, you should make a rally car!
I try to do my own maintenance but I took my Forester in to the dealer for an oil change that was included with the purchase of the vehicle. I now remember why I don’t go to the dealer. After I picked up my vehicle it made a loud clunk as I put it in gear, they left the fuel door not fully closed. I got home and did a once over and found my air filter cover not snapped closed. Then I did a long road trip which required an oil change on return. The drain plug was like the plug you had on that car, the oil filter and oil fill cap were also super tight. Then I went to rotate the tires and I needed a 25” breaker bar to get the lugs off. My standard cross bar wouldn’t cut it and I’m a big dude. Apparently the gorilla the dealer hired has never heard of a torque wrench.
It is THIS service (on my 2021 Forester) I would drive south to have you do. Looking at 40,000 km (as recommended for severe service in the manual) and that is probably two years away yet.
I see you doing some kind of partial transmission fluid replacement. In some videos I saw full fluid replacement - they just disconnect one of the tubes from transmission to heat exchanger, then start car for short period of time (to get about 1 quart of old fluid), then add new fluid into the transmission. And do this until you got fresh transmission fluid from tube. + Usually they recommend clean magnet inside transmission and replace the filter.
How do you thing is dangerous \ not required or better to do on high milage?
Have you ever seen the transmission leak from the torque converter/trans pump cover? It weeps down and drips off the diff drain bolt ,so it looks the diff is leaking. Subaru has a TSB out on this. I had to have my forester done this week. Found to be bad RTV from the factory, The mechanic sad it never cured right . Its a pretty big job the trans needs to come out and the pump cover needs new RTV and seals needs to be replaced.
After all that, did it work better for you? Thanks for the video
Thank you.
Much appreciated.
Thanks for the update Robert great job as always ❤❤❤it. Take care of yourself and family and Girlfriend and be Blessed ❤️❤️👍.
Is it possible to do a CVT relearn without a bidirectional scan tool ?
I cannot afford the TOPDON scan tool that you use (currently $4K). Will the TOPDON Artidiag pro do everything needed to change CVT fluid (measure temp, clear adaptives, AT Learn)?
Wow. 223000 miles
Which model Topdon scanner are you using? And if I'm shopping for a different model what text would I search for to ensure I'm getting the AT relearn?
Mr Subaru; If I put a little air pressure into fill plug hole, would I be able to force out any add’l old fluid? Maybe make a hose fit tight into fill plug hole and attach to a foot pump like used to inflate air mattresses?
Thank you for the time and commitment to putting these videos out!
I have this car with 210K miles and never had a CVT fluid change. I think the CVT is leaking and I’m struggling to find where. I was planning to do the fluid change as a start but I’m don’t know if that’s a good idea since it’s never been serviced. Does anyone have thoughts?
Thanks! I'm about to do this on our '16 Forester at 136k. I see you're using the Phoenix, is there a more affordable topdon tool that can do the relearn?
Something that a home users can afford.
I noticed while driving with the windows down I can hear a sound that resembles crickets from underneeth at certain rpm. I suspect the cvt but the fluid got replaced only 30k km ago. I can't feel/notice any chain slipping when it happens, just the sound of something slipping/grinding.
Have the wheel bearings checked.
Could I use valvoline cvt fluid for the first drain and then use Subaru oil for the final fill to save some money?
HELP!! I have a 2013 Impreza. It was throwing a P2764 and a P0700. I replaced the CVT Valve Body. The P2764 went away but I still had the P0700 and the dash warning lights. I then replaced the Transmission Control Module under the dash. No change. I now drained the transmission fluid, replaced the filter (not a filter), and put in new fluid. I cleared the codes. Once I drive it about like 20mph all the dash lights come back on and I get the P0700 code again! I don't know where to go from here? I don't have the Subaru Tool for codes or diagnosis since I'm not doing this for a living. Any suggestions would be appreciated.
Excellent, does anyone know the fill and drain plugs torque specs?
Thank you for video. Blessings to you.
Why does it seem as though no one pulls the drain pan and change the trans filter?
Seems to me like a bit too much trouble, for not that much gain. No gasket available. Have to let the Permatex cure. Takes several hours instead of one.
There’s not a filter on these
Do you need to wipe the AT learning mode or can you just do the flush? Additionally, how many times should you flush - till mostly clear?
It’s interesting to note that my 2021 Forester doesn’t call for CVT fluid changes just inspections.
Why do you need to do AT learning? So we can't change the fluid without doing AT learning?
Hello MrSubaru what kind of scanners do you recommend under 500.
Under/close to $500, the Topdon Artidiag900BT is great - www.topdon.us/search?q=artidiag900bt%2A&ref=FbllMMFzVRFf0i&type=product
There is a small bump on the side of the transmission. Is there a little cartridge filter in there? It is a small one if it is like the one that other Japanese transmissions sometimes have.
Can you please do a video on the cvt "filter" replacement or a full service taking the pan off, maybe even changing that solenoid that goes bad, any preventative maintenance to keep these bad boys alive 😂
Dude you’re awesome! Ty for another amazing video!🎉
Mr. Subaru, I have a 2019 Outback Limited.
Drained CVT FLUID 4 qts drained BUT after refilling with 4 qts no fluid dribbled out the fill. So I topped it off with a fifth qt. Still no fluid dribbling.
I was afraid to put any more fluid so I put the fill plug in and started the car and went through the gears.
Well a bunch of lights came on!
Eyesight, check engine light, and it is now stuck in “off road mode.
I don’t have a scan or code reader, is anything I can do to clear the light or at least get it to come out of “off road mode”.
Lastly I did let the car warm up to 95 degrees and checked fill plug and had no fluid dribbling, I intend to put another qt in until it’s dribbles out.
We recently purchased a certified used 2021 Forester and love the vehicle. My other Subarus are all older and out of warranty and I have the CVT fluid flushed regularly. My concern is Subaru of American says not to change the CVT fluid. As long as I have the Subaru service center do the flush will that void my CVT warranty?
I was surprised when I called around locally trying to find even an independent Subaru specialty shop willing to do a cvt service on our 14 forester, and they all refused, saying that they’re ‘lifetime.’ This was within the last year.
We finally decided to sell the forester earlier this year and bought a newer outback. Hopefully the official word from soa changes in the near future so I can get the transmission serviced within the extended service period. I’m not comfortable not having fluids changed *ever* but also not thrilled about possibly doing it myself.
How much fluid do you use to flush total ish
How many quarters do I need for the two flushs? Six for each flush?
Nice work, thank you for great content!
If a bolt broke off taking the transmission pan off. Would it seal with a bolt missing using rtv?
Does the 2024 Outback have a drain plug on the cvt?
Hi got a question how many quarts of oil should i used to do the same steps you did, and is recommend to change the filter also or no? Thank you.
do you have video on the air bleeding procedure of the control valve, after removing and replacing atf on a 2010 forester. or do you feel it is not needed when doing a drain n fill on the auto trans? Cheers!
i have a 2018 forester 2.5l premium trim that has about 115k miles and the CVT fluid has never been changed... at this point, because its well over 100k, should I just leave it untouched or ignore all the false Subaru marketing claims of "lifetime fluid" and not ever needing to replace the CVT fluid?
Just found your channel. After getting up to temperature and rechecking the fluid level is the car running or off?? Sounds like the car was running in the video.
Could this be done my taking a temp measurement of the pan, if you don't have a diagnostic tool?
Hi Mr. Subaru, thank you for your videos! May I ask a question: do we need to change the transmission filter when we change the fluid? Thanks!
So I have a 14 forester with 120 k on it. Had dealer do the first cvt at around 60k and a local independent subaru specialist shop do a drain and fill about 500 miles ago. Have been experiencing some shuttering now when accelerating in stop ang traffic. Could that be because they did the relearn process or because they didn't? Or sign of something worse?
Hopefully they used the correct CVTF, and properly filled it. That would be more of a possible cause than not performing a relearn.
Well lovely, that'll be an awkward return visit and not a great first experience with this place.
Love your videos btw, you're like the car care nut guy but for subaru.
Would hope you make a future video where you can elaborate on the cold start timing chain rattle issue, and when you'd consider it serious enough to warrant the repair cost. Not sure when mine started but in looking through many a subaru forum online it seems like people have had this for many years with their vehicles but just live with it.. And not a lot of folks returning to say it torpedoed their engines years later... So not quite sure how concerned I should be.
@@romdm7071 ouch. Yeah not great. If the issue only started right after their service, I’d say that’s a 🚩
Yeah, really wanna give them the benefit of the doubt and hope it's something else, as they're supposed to be a reputable shop with good reviews.
Only thing I could add is it's not consistent.. Not even something I can can say for sure I feel everyday.. And pretty sure not when cold.
When researching found someone elsewhere with similar issue that described it well... Like trying to take off in a manual in too high a gear.. But doesn't happen from dead stop. Only at times during acceleration in slow moving traffic
How long does it take to get the fluid to 95F from idle? Is it too hot right after driving 20 mins?
How often to do this on a car bought new? Do you need to do the "rinse and dump" if you do regular drain and fill?
I added a comment a few minutes ago, went to check for responses and my post was missing. Before re-entering, am I doing something wrong?
Do you guys do the relearn just for drain and fill? I thought relearn was only needed for valve body or solenoid changes?
Whats the best way to fill it without using that pump?
Mr Subaru, is the first refill to flush the valve body and any old fluid in cooler?
Thanks for another cracking video - saved it before I watched it even :) Have my new to me Forester just arrived from Osaka, 2.0i CVT with Eyesight and approx 44,000 miles on a 2014 plate. Thinking of doing the CVT as I can't see it being done in the history. Quick question is I may? Subaru CVT fluid is ferociously expensive here in Ireland, is it ok to do the flush with other brand CVT Fluid (meeting Subaru specification), drain it, and then do the final fill with Subaru fluid?
I’m learning so much from your videos! Is the AT relearn always needed after a CVT fluid change?
🙏 Thank you.🇦🇺🇦🇺🇦🇺
Why is the drain at a higher position than the sump?
Hi Mr Subaru I always watch your videos you're doing i great job.I have a big problem with my g4 and I think the mechanics are just riping me off and making things worst
What is it "learning" I wonder...can we just replace the fluid?
Do you change the filter as well?
My 2011 Legacy is coming up on 200000 miles. The last time the fluid was changed was about 100000 miles ago. It shifts and runs well. Should I leave it as some say or should I go ahead and change it?
So it seems that you need scan tools to change the cvt fluid or is there a way for the average guy to do this?
Am I missing something. What about the filter??
is it NOT recommended to do this service (on your own) if we do not have the computer to do the re-learn process?
I was wondering the same. I don't want to mess it up by doing it poorly and I'd like to do it myself, but I don't think I can get that sort of diagnostic tool now. I'm used to the pretty basic drain/fill on older cars.
Do Subaru's not have transmission filters or is that not something that needs to be changed?
is it possible to do this without the relearn? if not, is there a consumer tool that can be bought to monitor the temp and do the relearn?
So today my 09 WRX hatchback would not get out of reverse and my clutch pedal was not returning unless I pulled it back up. Any ideas🙏🏽
Does no one change the filter in these cars? I've never done a trans service without a filter, but subaru doesn't seem to change them.
Hi, I have a Forester with code p0841, they recommended that I change the oil and the transmission filter along with the transmission oil pressure sensor.. is it recommended to change the filter as well or just the oil?
Wow would you say that cvt was about 3 qts.low?
@MrSubaru1387, what about the front and rear differentials? Do those also need to be drained, or will this do that as well?
