I have a 2019 Ford F150 with a 10R80 transmission. It has been shuddering and has erratic shifting. Now it is at a dealership and they want $9000 to repair a known problem. It appears that Ford and the NHTSA are aware of this problem with these transmissions. The problem has been going on since Ford went to these transmissions. When will the Federal Government step in and make Ford have a safety recall. Going from 8th Gear to 2nd gear is like hitting a concrete wall. Ford has several Bulletins out for repairing these transmissions but refuse to inform the consumer. So if this problem happens outside of the warranty Ford wants to get paid. Please help the American consumer and hold Ford accountable for the defective product.
