Hollywood1 Posted 4 hours ago Report Share Posted 4 hours ago I just thought I would write a quick post about some maintenance that I performed yesterday. I am on my second edge ST now coming from a 2020 to a 2024. I've got about 16,500 miles currently. Yesterday I did a complete fluid change. The radiator fluid tested fine and was pretty easy to swap. The rear differential was very dark, almost black and the new fluid is a caramel color so it was definitely at the end of its life. The PTU wasn't as bad, but definitely a dark, dark brown whereas the new fluid again is a caramel color. I also figured that it would be a good idea to do a transmission drain and fill since I've been getting a hard 1-2 shift. The transmission fluid definitely had a slightly burnt smell to it and was nearly black and the new fluid is a red color. Just a heads up to anybody who is wondering about the maintenance intervals that Ford recommends, I would definitely do them early. I got all of those fluids from rock Auto for about $100.
