Hello all. Sorry to beat the drum again, but I wanted to get some opinions regarding transmission fluid changes/flushes. I recently purchased a 2014 Highlander Limited Platinum that had 82,300 miles. I put on another 2k miles and decided to look into transmission fluid changes since the previous owner never serviced this fluid. Some people say to do it before 100k, some say do it every 30k once you get the vehicle brand new. Has anyone changed their transmission fluid around the same mileage as me for the first time and has it worked out since (with no shifting issues)?
