FORD F-150s' : '2015 - '17 being investigated ...

Interesting. My fiancé owns a 2017 F150 with this transmission that she bought new, but she has never experienced any of the issues described in the article.
 
Oh no, more issues with Ford.......

I never ran into that downshift issue, thankfully. There were some wonky shifts but I expected as much from FoMoCo. I was more worried about seatbelts catching on fire.
 
They cover this but the CDF drum and valve bodies never became a recall? Sigh.

For all it was, I really, really liked by 2018 f150. The transmission was a crying embarrassment and a primary driver in trading it last year.

Was that the 10 speed? 6 speed better or no experience?
 
I think this all related to fine metal dust shorting out the leadframe which is essentially the wiring for the valvebody and includes the range sensor and I believe the output shaft speed sensor on the 6R80 transmission which a Ford licensed ZF design. Ford knew there were issues with fine metal contamination and there's two magnets in the transmission pan of the '15-'17 F150. The earlier ones also have this issue with only one magnet, and I believe there's been recalls and investigations on these.

I have a '15 and a'16 F150. The '15 was a no crank because of dust shorting the range sensor at about 150,000 miles. The '16 has 234,000 miles and I changed the $250 leadframe proactively, because I know there's issues, and the truck lives 1100 miles from my home. The factory service manual recommends a 150,000 service interval. The Mercon LV in these comes out looking like motor oil with those miles. Both of my trucks have had TC shudder issues which is also common. If you have a 6R80 equipped Ford with over 100,000 miles, I'd recommend getting a transmission pan with a drain plug change the fluid three times in 10,000 miles and then every 30,000-40,000 miles after that. It's literally a 15 minute job with the pan plug and a bucket pump. A drain and fill is just over 7 quarts of the 12-13 quart capacity. It's actually a really good transmission.

6R80's can malfunction and not see the OSS sensor and shift down to first or second at expressway speeds. Obviously very dangerous. The '17-early '22 10R80 is dangerous to the owners bank account with dealer replacement costing $8,000-$9,000 and aftermarket overhaul $4500+.

The 10R80 CDF drum issue was addressed in late '22, so good after that so far. I wouldn't own a pre '23 10R80 truck unless it has a service contract or a updated CDF drum. The 10R80 offers better acceleration and towing, but the '15-'17 6R80 trucks are considered to be more reliable with way less transmission issues, and many consider the '15-'17 5.0 and 3.5 to be more reliable than the '18-'20 5.0 and 3.5 engines.
