Good morning people and Happy New Year to you all. I'm new here and trying to be more hands on with my Jeep Wrangler due to the crazy rise of mechanical costs. Question, I have a 2016 Jeep Wrangler with approximately 190,000 kilometres on it. Besides Oil and brakes I haven't done much else. Looking at being more hands with "minor' maintenance. Wanting to change the transmission and transfer case fluid. Some threads I've read about the transmission fluid is due to the amount of kilometres on the Jeep it's better to leave it alone because I may run into some "problems" ... Some expert advice would be greatly appreciated .
