At 75k, it's probably filthy and the fluid well past shot. A mere flush/refill will probably expose deposit/contamination related problems.
Three letters: ARX.
ARX it and then refill with Dex VI. With that mileage on the factory fill, I'd be looking at a pan drop/filter change as well.
No need to put a drain plug in if you can use the cooler lines, which makes for a better flush anyway.
