10R80 Transmission Transmission has very prolonged delay when switching to certain gears which results in loss of power when merging onto roads causing near misses because it takes so long to engage the gear. Truck has zero power during this shift delay. The shift delays are caused by an issue that ford KNOWS about where a bushing (CDF drum) shifts a little bit inside the transmission. Vehicle is not safe to drive. When the gear finally does engage, there is a violent jerk/surge forward which can be impossible to control.
