Acceleration lag in a rolling or standing start. Most noticeable when stopped with truck facing uphill or slowing to a near stop and then slowly accelerating (slowing for a stop light that turns green as you approach the intersection). Once acceleration kicks in, the vehicle jumps as if the transmission has dropped from neutral to being into gear at increased rpm's or the clutch has slipped. Gear indicator doesn't show vehicle had ever dropped into neutral. If acceleration rate is increased from stop or rolling start, problem does not seam to occur. Problem was noticed from beginning of ownership and has been intermittent ever since (truck was purchased new in March 2015). Have not taken to dealer for diagnosis as it is intermittent, but talked to a non-Ford mechanic that had heard of other people noticing acceleration lag.
