I plan on driving 5 hours in my TJ in about 3 weeks. I plan on giving it an oil change since it is about that time anyways, checking all of my fluids, and checking my air pressure. I was thinking about doing a transmission fluid change since I have never done that in my ownership of the TJ, but wasn't sure if it was necessary just yet. Would it be beneficial to change my tranny fluid before leaving? Also what other things should I check on just in case?
