2015 2.5L Legacy- 128k CVT Transmission pump out- Still running well until I turn.

Long story short I had the wrong fluid put in 2 yrs ago, just realized it added the CORRECT fluid and boy did it freak out and shuddered horrible. Had it re flushed again running so much better except when I turn. My guy says the tran pump is out and it will eventually fail. HOW long do I have to figure this out?
