Saw this on the other F150 forum and didn't see it posted here when I searched.

I've been seeing behavior like this, especially when it downshifts 4 -> 3, so I'm going to take it in next chance I get. Hopefully this will do this trick.

"Some 2017 F-150/Raptor vehicles equipped with a 10R80 automatic transmission built on or before 1-Aug-2017 may exhibit harsh or delayed shifts and/or an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0711 stored in the transmission control module (TCM)"

I noticed a lag up shifting from 3-4. Maybe this will take care of it. Some days it feels like an inexperienced driver using a manual and can’t find the next gear

Yea my truck gets weird at times too but I have an 18.

Mine some days seems real harsh from 1st to 2nd like whiplash harsh then other days seems fine....

I dont notice any issues from 3-4 though.

Thanks Morn

Good to know. Im not seeing any "Outstanding Field Service Actions" on the FordEtis site for my vehicle or anything on the Ford Pass app so fingers crossed.

Mine is actually an ‘18 as well, built in early August if I recall correctly

“built on or before 1-Aug-2017”

Lucille falls squarely within that era, but, I don’t feel as though there are any drivability concerns. She was also held at ramp 59, as well as run through a 2nd q/a - I posted the punch list after Lucille and I got together. It was 4 pages and quite a few miles.
