Hello, I have a 2012 Toyota Corolla automatic 175k miles bought used from a private party. It has a P2714 pressure control solenoid D Performance/stuck off. It shifts fine smooth like normal up to freeway speed of 70mph, but when i accelerate from 70-85mph, it dances between 3-4k rpm. That's the only time it acts funny. Above 85mph it seems fine. The transmission fluid was gray (like it has never been changed). I Flushed the system, now all IM readiness are in the green, but the P2714 would come back if i'm happy on the throttle between 70-85mpg. My next plan is to replace the solenoid, I have looked on the internet but it's been mentioned on top of the transmission and or inside the pan. Where is it? Thank you.
