    I have a 2007 Limited with 259k. After my recent oil change I decided to check my transmission fluid since it has been a year since I changed one of the shift solenoids. When I got under there to press and pin the trans cooler bypass open the little bypass button wouldn’t budge. The trany was only slightly warm (90 F) after the oil change leak check so, I let it cool for quite sometime but it still wouldn’t budge. Haven’t driven it a lot lately but did some towing in December and had zero issues with overheating.

    Anyone else experienced this? Feels like I’m missing something simple.
