Sad to say that PTU was not one of Ford's "Better Ideas". In my OM it says the PTU dry fill is 23.7 oz, so you're not going to get all of it out during a change. Thankfully on my 2017
2.3 EB it appears to be easy enough to access. I know you had a 3.5 EB. Maybe my inline 4 cyl engine allows for easier access than your V-6 did. I had the dealer change it at ~9,000 miles, it costed $110, including labor and fluid. I read that earlier non EB engines do not have a drain plug on the PTU. Mine does and it appears relatively accessible. Possibly my 2017 might have cooling on the PTU, earlier ones didn't. I'll do more exploring to see how feasible it is for me do it myself. And yes the "it never needs service unless the warning message appears" is ludicrous. Almost as bad as the transmission fluid is good for 150,000 miles
. I did a transmission drain and fill at 12,200 miles and the fluid was very dark brown. The dealer said it was a sealed unit and the only way to change the ATF was with the ATF flush machine
. Between my family and myself we've mainly owned Ford's for 50 years, and always had good luck with them. Hopefully with maintenance I'll be able to keep this 2017 Explorer for as least as long as our 2005 Explorer with 194,000 miles and still running good.
