Evidently there is a problem with the CDF clutch cylinder. There is a bushing that will slip and can cause delayed or rough transitioning into gears. This is on the 10R80 transmission according Ford. We had no idea of this issue till we brought our truck in to Ford to have the system flushed. Which then the service tech asked had we had any issues and we said it has a delay when shifting into gears sometimes as well as when we put it in reverse it seems like it dsn’t fully engage and and then when it ds engage it is like a jolt and the truck gs at a faster pace since we was pressing the gas thinking we did not give it enough gas to go into reverse. Multiple times my wife has said that it ds this when she is backing out of our driveway into the road also while she is backing out of her parking space at school. What is bad is there are no warning lights on the truck for this issue. There are multiple recalls on this transmission that involve updating the computer settings for the trasmission but the real issue is they have not done a recall for this issue which would stop the bushing from sliding causing the delayed/harsh shifts. Since this is an engineering design issue and potential Hazzard while drive this should be a manufacture recall. Ford has already resigned the cylinder in 2022 to address this issue but anything manufactured before that is suppect.
