The 2014 Owner's Manual requires that with severe service the ATF should be changed at 45k miles.
I got to thinking that perhaps driving across country with 6-7 days of 500+ miles a day at 65 mph might be considered severe, so I had mine done by the dealer this week at 54k miles. It cost me $250 with tax. I'm considering that cost an insurance premium against a failure of the transmission. Tomorrow I begin another x-country road trip, which will make the third time crossing the country in the car. I've got 1k miles on the new Continental Purecontacts, so they are well-seated (so-to-speak). They have pretty much held the 45 psi for the month they have been on the car so I'm satisfied they are good-to-go.
LLninja - welcome back my friend 8^) You probably know how to test the shocks for wear: push hard on a fender four or five times getting a good rhythm, then stop and count the number of oscillations before the car comes to rest. IIRC, there should be only one complete oscillation for a good shock. To verify, I just did it on my car and there was one oscillation.
