rmc523 Posted February 3 Share Posted February 3 Feds Investigating Nearly 1.3 Million Ford F-150 Pickups with Serious Transmission Problems - Autoblog The Blue Oval is facing a new headache over older pickup trucks. The National Highway Traffic Safety Administration opened a preliminary investigation into 2015-2017 Ford F-150 trucks on 21 March 2025 due to reports of issues with 6R80 or 10R80 automatic transmissions that may unexpectedly downshift without warning or driver input. The NHTSA has now upgraded that query into a full investigation, covering 1,270,970 examples of the pickup, after more than 60 percent of surveyed owners reported problems to the NHTSA’s Office of Defects Investigation (ODI). While this is not yet a recall, the frequency of complaints may lead to one. Quote Link to comment Share on other sites More sharing options...

Maybe a sensor I guess. For the record I've had no issues at all with my 2018 3.5l ecoboost. 2 Quote Link to comment Share on other sites More sharing options...

For the record I've had no issues at all with my 2018 3.5l ecoboost. I did have to have my 2018 Mustang Ecoboost reflashed at about 42,000 miles. No problems since then. I’m at 96,000 miles now. 1 Quote Link to comment Share on other sites More sharing options...
SoonerLS Posted February 4 Share Posted February 4 They had this same (or a very similar) issue with the 6R80 in the 12th Gen where it would unexpectedly downshift to 1st at highway speeds. The recall solution (which was done to my ‘13) was to alter the programming so it wouldn’t do that. As I recall, the problem was a momentary loss in communication with a sensor related to how the truck knew what speed it was going, so the truck would think it was stopped or moving slowly, and would shift to 1st to deal with that. That’s ok if you’re actually stopped, but no es bueno when you’re doing 65. The solution was to get the PCM to ignore the momentary drop-out, and boom (or, really, no boom), problem solved. 2 Quote Link to comment Share on other sites More sharing options...

My ‘13 F-150 has well over 220,000 miles on the clock, and the only real problem it’s ever had was the water pump. It is, far and away, the least problematic vehicle I’ve ever owned. My late mother’s 2017 Flex is coming up on 150,000 miles, and it has been basically trouble free, too. 1 Quote Link to comment Share on other sites More sharing options...
