The other day my CVT overheated while driving on the freeway and went into safety/limp mode, I checked the temperature for the ATF and it showed (-113C°) I added a auxiliary transmission cooler and it climbed to (123C°) during normal street driving it hasn't gone into fail safe mode yet but i want to troubleshoot it before I deem the transmission trash and replace it .

I've added some stats for reference

I read that the cvt-b count is how many times it has overheated, but I've only recently acquired this car and have encounter the safety mode once .
