NHTSA Complaint #11708380 — 2018 FORD F-150

Ford has issued multiple TSBs regarding THE DEFECTIVE 10R80 10-speed automatic transmission, particularly in F-150s (2017+). The issue is around the CDF drum in Ford F-150s (and other vehicles with the 10R80 transmission) is a known issue where an internal bushing can slide, causing significant fluid pressure loss, erratic shifting, and potential transmission failure, especially in models from 2017-2023. Ford was aware of this because they released multiple bulletins, and they even redesigned the CDF drum with JL3Z-7H351-B to fix the problem, but never issued a recall notice. I was leaving my house, and my truck did not move. It revved up to 5 thousand rpms, and then a loud bang noise happened, and then the truck moved. I took it to the dealership, and they said the CDF drum failed, and now they quoted me $7,000 to fix the known issue. When I called Ford to ask for some sort of assistance, they responded that I should have purchased the extended warranty. This is not right that they knowingly have a defective part and are refusing to issue a recall or offer some sort of financial assistance. I drive a 2018 Ford F-150 XLT 5.0L that has no mods or ever been tuned or modified; mileage is roughly at 121,000.
