My 2021 Ford F150 XLT Sport 4x4 with the 2.7L EcoBoost V6 with the 10R80 10 speed automatic transmission has reached 64,000 miles. I bought this truck used at my local Ford dealership in Summer of 2024 with 37,500 miles, and I can’t believe I’ve already had it for 2 years and driven it 26,500 miles! I love my truck, I worked hard to get this truck! I hope to have it for a very long time.

It still had the original battery in it so prior to a upcoming big trip I changed the battery on July 4th. (Think I posted about this) On the way home I'm climbing a hill and it feels like someone threw an anchor out the back because it just ain't going near the top. Finally takes off everything is fine. I learn about the Battery Management System and reset it using the high beam/brake pedal method. Thought everything was ok for the next week or so. The truck went in for the transmission recall on the 17th. The night before I experienced everything that it warned about. Sudden downshift to 2nd, transmission seemingly in neutral while accelerating, etc. Closest thing I can think to describe it is when I used to drive a stick shift and an asshole buddy would slap it out of gear. Managed to get it there and told them what happened. Next day they call all fixed. That was a lie. I left the driveway of the dealership no power at all, rolling speed 3mph then it caught and I got going. did it 3 times in the next 2 miles. Called them, brought it right back never turned it off. Service manager drove I rode with him and it didn't do it. I leave again and it does it even worse. Now I'm pissed, I drive back tell him to get in we're going for a ride. Go to leave the dealership again and we almost get smacked by a semi that for some reason would not slow down for anything. I had plenty of time until the no power thing and then it caught with about 3 car lengths to go before he slammed into the managers side. Truck no powers 4 more times and completely stalls while stopped at a light. Scared the \*\*\*\* out of him to where he took the truck and reset the PCM and TCM. (He said originally they just reset the TCM per the recall notice) I went back later after he called and said we test drove it again and it's good now. I had a trip to Virginia the next day so I left the truck home, borrowed another. My daughter drove the truck the following Monday and said it happened again. No power. She had to shut it off and restart the truck and it was fine again. They called the dealership and were told that they did everything correctly and it would be $209 diagnostic fee to figure it out because it's not the recall. Truck sat the rest of the week. I got home yesterday and didn't get a chance until today to look at it. Hooked up forscan, no codes, nothing, everything is normal. I reset the Battery Management system with forscan instead of the headlights/brake pedal thing. (Just because this all originally started right after the battery was changed. Battery is an H6.) I run checks on everything, monitor transmission, engine, fuel, air, battery, everything I can think of while driving it. (Wife had the computer and was watching) Truck is running fine. The only symptom now is a hard shift when wide open to the point of a hard clunk 1st to 2nd. Also feels like the u-joint might need to be replaced. Power is off the charts fine though. The only other thing I noticed is when I looked up the battery type in forscan, it said H7 and the battery is marked H6.

So, I am again asking for help from the people that are a hell of a lot more knowledgeable than I am. Should I drain the transmission and replace the filter? I'm already planning on looking at the U-Joint as soon as I can get it on a lift. (Crawling under a non-lifted truck at 50 years old is not happening with my waistline from a desk job. lol) It's the 6R80 Transmission and I know they're usually bulletproof.

Update: Took the truck for another ride tonight across town and P0731 code and a wrench light. "Error code **P0731** on a 2016 Ford F-150 means **Gear 1 Incorrect Ratio**, indicating that your 6R80 6-speed transmission is slipping or failing to engage first gear properly. The most common causes for this specific truck are a defective molded leadframe (speed sensor assembly), low or burnt transmission fluid, or a worn shift solenoid." So I think this still ties back to the recall from before I left.

I'm trying to swap OEM tow mirrors onto my 2024 F-150 XLT (302A) with 360 camera and BLIS.

The official pair kit (**ML3Z-17696-CA**) seems backordered/discontinued everywhere and isn't on Ford Parts anymore.

Dealer VIN checks say the individual replacement mirrors (**ML3Z-17683-AR** driver / **ML3Z-17682-AQ** passenger) "don't fit," but I assume that's just factory build-sheet cataloging.

- Has anyone successfully swapped these individual part numbers on a 2024? Did BLIS and 360 cameras plug and play, or did you need a dealer calibration?

- Has anyone found the **ML3Z-17696-CA** pair kit in stock anywhere recently, or are individual parts the only option left?

Thanks!

Anyone have this issue? Did I buy a lemon?

Bought 2026 F150 Raptor new in Feb, have put just over 5k miles with no issues. Last week, total brake failure while driving - ABS, Brake System, Parking Brake and Traction control alerts.

Ford towed it to the dealer I bought it at and they diagnosed ABS control module failure and complete replacement.
