NHTSA Complaint #11707667 — 2020 FORD RANGER

I bought my 2020 Ford Ranger preowned with around 64k miles on it. After having owned it for about 6 months or so, I started to notice lots of problems with the transmission. After first noticing it, the problems persisted for a couple more months until I finally decided to address it. The problems were very characteristic of transmission slippage, and they got progressively worse week by week, which it what ultimately prompted me to address it. When accelerating and shifting through the lower gears (15-30 MPHs, approximately), the shift would be delayed and lag a couple seconds. This would often cause stalling in the acceleration, particularly when going from a stop to a start, such as through traffic lights. There were also very rough and aggressive shifts at higher gears when driving on the highway. It would feel like rough jolts that would rock the truck a little. Also transitioning the truck into reverse often caused serious jolts as the transmission shifted very aggressively. Eventually, I took my truck into an AMCO transmission shop for inspection. They confirmed that my transmission was damaged and needed replaced. This was at about 86k miles. I took the truck into a Ford dealership to get a second opinion and they also confirmed my transmission needed replaced. I went ahead and had the transmission replaced at that point. The replacement was done with the truck at 86k miles. The Ford dealership replaced the 10R80 transmission with a re-manufactured 10R80. It has now been about 8k miles and 9 months since the transmission was replaced, and the re-manufactured transmission is starting to experience similar problems. Mostly with a lag when shifting in lower gears and hard jolts when placing it in reverse. The problems are not as bad as the original transmission before I had it replaced, but some still remain. There were no warning lamps or messages with this problem. Ford's 10R80 transmission is notorious for failing and being a safety problem to the public.
