When the vehicle is cold, and the transmission has not yet warmed up, putting the truck into gear results in a significant jerk. Specifically: Initial Gear Engagement (Drive/Reverse): When shifting into either drive or reverse from park, especially when the engine is cold, there is a noticeable delay before the gear engages. This delay is followed by a harsh ‘jerk’ or ‘thud’ as the gear finally engages. Reverse to Drive Transition: When shifting from reverse to drive, a similar delay and jerk occurs before drive engages. Hard Shifting: In addition to the initial engagement issues, the transmission exhibits delayed and harsh shifting for several minutes when cold. Shifting is not smooth and seems delayed then shifts very hard and aggressively when driving during the warm up period. Clunking Noises: While driving, I intermittently hear clunking noises when the transmission shifts gears. This occurs at [ Mention the specific times or driving scenarios when you observe this — e.g., ‘low speeds,’ ‘during upshifts/downshifts,’ ‘when accelerating,’ etc. ]. These problems are most pronounced when the engine and transmission are cold and seem to gradually improve (though not completely disappear) as the vehicle warms up. I am concerned that these symptoms indicate a serious problem with the transmission. I have asked a Ford Dealer to look at this and they state that there is NO RECALL for my VIN #. They have always appeared since I purchased this truck.
