Some 2015-2019 MKC and 2016-2019 Explorer vehicles equipped with a 2.3L engine may exhibit a vibration/rough idle when the vehicle is in drive (D) or reverse (R). The vehicle may also exhibit a lack of engine revolutions per minute (RPM), lack of acceleration on take off and/or shudder while driving. This may be due to the torque converter overheating causing damage to the torque converter as well as possible internal damage to the transmission. To correct this condition, follow the Service Procedure to replace the torque converter and specified internal transmission components that may have been damaged.
