I took delivery of my Brand New F150 8-1-18. On 8-2-18 the transmission started too slip / chatter when shifted to drive or Reverse ramdomly. I brought it to the nearest dealer and they said it was normal.. 5 days of dealing with this , I brought it to another dealer who added a couple of quarts of trans fluid.. I took the first trip up the highway with the truck with 200 miles on it and the transmission was slipping in all gears and blew a bunch of transmission oil out the back of the truck. Towed it to a 3rd dealer and they said the 2nd dealer over filled the transmission. Went 6 days with no vehicle. Got it back yesterday, took the same trip home with it, and the POS transmission was slipping the entire trip. Fluid temps average 235F. Now it's back at the original dealer that over filled the transmission. Now I'm without a vehicle again until further notice, no loaner car available. Called ford customer service, they are 100% useless!!!! The dealer did say that several trucks are having the same problem as mine and ford will not change the transmissions until they figure out the problems.. I traded in a perfectly good 2016 F150 for this POS with more bells and whistles Stay away from these 10 speed transmissions!!! Oh yeah a Ford Rep did call back and gave me free oil changes for 4 years, I told them keep that **** and put a transmission in the truck or buy this POS back..( neither are they willing to do) It only has 350miles on it..

Very disappointed in them!!! (Ford)

Thank you guys for the comments. I have met the criteria for lemon law at this point.. I will be pursuing it!! An update about the F150, it's been over 2 weeks with out a truck now. I picked it up at 8am this morning from the dealer, at 9:15am, I'm waiting for a tow again. Transmission is over heating and not shifting and slipping.. Can't make this up!!! Service manger said ,"blow it up good so they will be able to change the whole thing".. Problem is, dam thing just slips and will not blow up.. It cools down below 230 degrees and works again ( somewhat) ..

I have a 2018 Ford F-150- lariat sport. I have 2 issues the transmission is slipping in cold weather, it shifts rough in all weather and it seems to rev at times. I have to take it in for this issue it seems to be getting worse as it gets colder. I’ve read that others have had the same issues.
The second issue is a pumping noise when I open the drivers door after it’s been sitting for awhile. It’s coming from under the cab near the rear of the cab. I took it in for service and they advise it’s normal. It’s the fuel pump priming. I said who would design a vehicle with this annoying noise. Doesn’t seem right. Has anyone had the same issue?

Lemon Law that truck. Don’t give up, don’t settle. Make them take it back.

good luck..

My suggestion would be, you drive the truck with tech in it.. Have them acknowledge too you the problem exist.. And record them!!

I'm still going through lemon law procedure.. Transmission been apart 4 times now but continues to slip when it is warm and everytime.. Ford will not change the trans out!! Only 3000 miles on this truck now.. I have many case numbers on it too from ford.. Electrical issues, head liner came down and unglued, electric fuse box ( under hood) was wired wrong, tow 7 wire plug wiring issue, and etc.. Only good thing is when I bring it in now, there is a vehicle waiting for me to drive.. It is going back in next week to the 4th dealer to try and solve the trans problem..

i have an 18 3.5 with 27k km on it and the trans just took a dump or at least 3rd gear. I have to have it towed to the dealer now because it’s oretty much not drivable, I had to drive it home in manual mode when this happened. So far otherwise I’ve had no problems or issues but have noticed the trans a bit clunky in past and had weird 2-3 shifts but just brushed it off. Now that I read ipnin the 10sd I can see that I’m not alone with the issues and it’s more common, my dealer tech told me on phone there’s like 9 tsb out on it right now.
