2012 CVT shutters when shifting gears or idling

Hello guys,

I have had minor shutters when changing gears (like shifting from park to reverse) and also just idling at a stop light, Iím not sure if itís the CVT or torque converter, but its gotten worse over the last year. The rpms will drop from 700 to 500 for a second or two, it has never stalled on me but it did sound close. Itís a 2012 with 94k original miles on it, but is still covered under Subaruís extended 100k warranty? Should I call SOA?

I do remember in 2013 my mechanic replaced the CVT fluid with ATF (I guess the older models w/o CVT use this?) at only 30k miles, and there were some shakes and noises that wore off on their own, which is weird, I didnít think anything of it, and now itís starting to have issues with the shutters where it sounds like itís almost about to stall out. Could this be a possibility?

I just had a drain and fill done with the appropriate CVT fluid, but after so many miles of driving with the wrong transmission fluid it really doesnít feel any different. It sounds smoother but itís the shutters when shifting gears or idling with city driving that make me a little nervous.

-Patrick

From memory the dropping in revs when coming to a stop is one of the reasons Subaru extended the warranty to 100k miles so I suggest you contact SOA fairly soon so that you can hopefully be covered under warranty.

If it was me I am not sure I would be mentioning that the CVT had the wrong fluid as this would potentially voice the warranty. Let SOA determine the cause of the problem, they are the experts.

Assuming you didn't address the error until now? So it survived 64,000 miles with the incorrect fluid. Wow. Probably because it was only a single drain and fill then, which would have replaced about 1/3 of the total fluid in the transmission.

That said, chances are extremely high that your transmission is toast due to this error. https://www.picknbuy24.com/column_349.html

Did you just recently realize he used the wrong fluid back in 2013? Quite frankly this should hit your mechanic's liability insurance, not Subaru's warranty program.

Thanks for responding, means a lot.

Spoke with the mechanic, found the receipt from 2014 as I save all of mine, and she explained to me the Subaru HP ATF was for power steering only. They just inspect CVTs. She said it sounded like it might be a torque converter issue but will of course have to inspect and drive it around.

Aah, phew! That is great news! Yes, the power steering does take ATF.

I’d agree with her about the torque converter as prime suspect, followed by valve body as second.

Either way you are covered under the extended warranty. If your mechanic is not at a Subaru dealership don’t spend money on her right now. Instead, call SOA, log a ticket, and bring the case number in hand to a dealership.

Anecdotal evidence on this forum points to less pain at dealerships for issues like these if you’ve already alerted SOA and they are watching the case.
