I hear different things about the difficulty of changing the ATF on Fords with this transmission. I'm 70, and not a DIYer. If I was convinced it was as easy as you say, I would be tempted to do it. But I see these videos about removing a wheel, some sight glass on the side you have to check the fluid level thru, and having the car itself perfectly level when you do it.We have 2017 2.3 EB Explorer with the 6F35. Changing the ATF is easier than doing an engine oil and filter change. An 11 mm plug on the bottom of the transmission to drain and to fill is through the vent under the air filter duct. The vent is easy to get to. It has a large yellow cap that is pressed in and pulls out. The vent tube is tall enough and wide enough to easily use a transmission funnel to add the ATF. Your vent/fill tube looks like Ford is serious when they say the ATF is good for 150,000 miles . I drained the factory fill at 12,000 miles and it was extremely silvery, no pink at all. 10,000 miles later it was still but less silvery and grey, no pink. Again 10,000 miles later it was much less silvery and slightly pinkish. This is a heavy and fairly powerful vehicle that has a smaller car transmission that appears to stress the ATF. Since changing the ATF is so easy I'm trying to maintain a ~20,000 mile drain and fill routine to hopefully maintain a longer tranny life.
I've seen the fill tube under the hood, and it just doesn't seem that hard.
The stories here and elsewhere about dealers and independents refusing to do this service, or not unfounded. I nearly begged a Valvoline instant change store to do it, and maybe get some of the BITOG coveted Maxlife, but no go.
It's frustrating, because I'm on top of all other maintenance.
I only drive about 6,000 miles a year, rural area, no stop in go, moderate climate. Maybe I'm over thinking this.
2015 Fusion 64,000 miles. Thankfully, I was smart enough to avoid the Ecoboost.
