I have a 2014 but I would guess the prices are the same?
Had my transmission drain and fill done for $210 and Rear diff done for $116. Coolant flush was $109. All done at Goodyear - No issues. I expected to have to tell them not to flush the trans (based on what I learned on this forum), but before I could, the guy at Goodyear said you don't flush these, you just drain and fill them.
*Mine is two wheel drive.
