Affected Component: POWER TRAIN

Summary
Some 2018-2022 Mustang vehicles equipped with a 5.0L engine and a 10R80 transmission may exhibit a buck/jerk sensation that may be perceived as an engine misfire during throttle tip-in between 35-45 mph (56-72 km/h) and with the transmission in 8th, 9th, or 10th gear. This buck/jerk sensation is a characteristic of the vehicle and can be compared to a like vehicle that is equipped with a similar powertrain (engine, transmission, and rear end gear ratio) driven in the same manner. A diagnostic trouble code (DTC) will not set because of this condition and no repair attempts should be made. If a misfire DTC is present, the DTC should be diagnosed first following the correct diagnostic procedure outlined in the Workshop Manual, Section 303-07B.
