I've got a 2015 GX460 with 183K miles and it's been a great daily driver for me. Recently the engine light came on and the code is this P2714 pressure control solenoid. It drives just fine and I haven't experienced any transmission related issues. The dealership says they won't open up the transmission for some reason or another and the only option is a new transmission for around $8K. Curious if others have experienced anything similar and if there are any other options to resolve.
