- Follow along as we scan this Subaru, test the components and repair the problems.
Subaru solenoid failures are common on these CVT transmissions. The dealer doesn’t offer individual solenoids so if you OEM parts you will need to purchase a complete valve body. There are some online course that sell solenoid kits but I don’t have any experience with those parts.
There is also several software updates for this vehicle to help with transmission operation.
Don’t forget to perform a learned value reset when you’re done followed by a test drive to complete the adaptation.
I had the same issue before with my 2012 impreza. I got a good/used original soleniod from ebay for CAD$200. Bought the gaskets and o-rings from the dealer for another CAD$150 and its been working without issues ever since. A new valve body + install is CAD$2500 from the dealer.
Valve bodies will often go on Subarus. No more cvts for me.
don't buy individual solenoids, they are aligned from the factory in the valve body.
I love the longer formats, Chad. I can’t thank you enough for sharing your knowledge and experience with us.
I tried to do the AT learning after a solenoid replacement on my valve body and keep getting session ended abnormally. message I saw elsewhere some people saying I need to run the rear differential inspection mode first and then the AT learn. Have you run across this? Other problem is my scanner does not seem to have this diff inspection mode. Any other thing it could be from preventing me from doing the AT learn?
m having codes of P2763 Torque converter solenoid circuit high and P0974 Shift solenoid Circuit high, Im wondering if the whole valve body needs to be changed or just the harness? I had a previous code of just P2764 Torque converter circuit low and I changed the solenoid but after a couple days the P2763 and P0974 showed up
I am currently going thru a big headache with a 2009 Impreza with the Lock Up Valve, still trying to work out what the hell is going on with it.
Thanks for Video, really appreciate some people with knowledge like you spend time educating others. Wife drives same 15 outback with 70k miles, it has the TR580 with TCM on top of transmission cover. I was convinced she had a Transmission issue but now not so sure anymore. I came to see what resistance value you would call acceptable and mine are all within tolerances when cold. Her issue if I was to try to explain feels like if you were to put a manual transmission in 6th gear at low speed, does the shudder only once, if you put some gas it does not do it. there are no check engine light or DTC codes in ECU or in TCM. Trans has fresh fluid. old one wasn't too bad just not as tacky as new one. fluid had been replaced at 35k miles already. originally my first thought was spark plug but no knock sensor code, mass air flow but reading dynamic value seems to work well then read about all type of issues with CVT and in particular the locking of torque converter that possibly happens too early on acceleration so if not enough gas it feels like a engine blocking. This happens in shift manual mode just the same. One thing more if I disconnect battery for let's say an hour (I guess all learning memory gets erased) then can functions well for maybe an hour (maybe until it gets to normal operating temp) then issue starts again. Then after that it can do it cold or hot just the same. I'm thinking issue is caused by a control module thus the reason it is not detecting something is wrong and not throwing any code. Thanks to anyone who spent the time reading and if you have any idea that could help thanks in advance.
Bloody awesome video, thank you for your time on doing it and showing us all. GREAT WORK BUDDY.
Great video, please keep them coming like this
Love the long version, thank you
Great video. Appreciate /prefer long detailed video. Nice work 👍
I like this video as I have a '17 Forester 2.5i( 180000 miles), CVT fluid changed every 30000 miles.
Check out the STIS Tech Tips Nov. 2020 article for TC relearn on test drive procedure, it's a separate procedure from the scanner relearn, it's not in the SI.
Great thanks
i like a start to finish video the best the length longer single videos easier to follow
Going full works for me ☕ 👍
great video, never knew that is so much electronic in this car !
What's P0971 on a legacy 2.5i? Thx
I have R2 automatic, doesn't move ? R or D
