2015 Jeep JKU Automatic Transmission Fluid and Filter Change?
With my 2015 JKU hitting 80000 miles recently, I realized I have put off the transmission (Automatic) service that I put on my to-do list at 60,000 miles. I have heard many jeepers tell me to avoid changing the transmission fluid and filter because of transmission issue popping up soon after. Looking for advise and/or experiences.

Your owner's manual recommends automatic transmission fluid/filter change at 120,000 miles for non-severe service. (Too long, in my opinion.)
Nothing wrong with a fluid/filter change at the mileage you have.

If it's done properly there is nothing to worry about. 60-80k is how I handle it. It makes a big difference when I got it done the first time. Make sure they change the filter.

I can't recommend enough, buy a pan with a drain plug in it, or install a plug in your factory pan!

Circling back around on this one with a couple tips.
1) using a mittyvac to suck as much out as possible through the dipstick tube is highly beneficial. If you do not, plan on making a nice mess trying to do a controlled spill when you crack the pan lose and drop it.
2) the rear bolts on the pan are a pain to access, and your exhaust cross over is going to be in the way. My exhaust is re-routed, so not even there, and it was STILL a pain in the butt. You'll need a torx nut and a nut driver to access them most likely. There is not enough clearance to use a torx sorx bit. Also, since the exhaust will be in the way, it will make doing a controlled spill very difficult, see #1.
3) if you do not have a mittyvac, and choose not to buy one, then do yourself a favor and either buy a new pan with a drain plug or tap your pan while it's off so you don't have to make a mess next time. I'll be buying a mittyvac at my next change.

Make sure when you refill you put in exactly what came out- I just did mine and had a bit of a panic after the first proper heat cycle. Finished a day of wheeling to find the side of the Trans covered in atf. I must have barely over filled it, just enough to have it weep out and make me a touch nervous.
