OASIS Broadcast wrote:Some 2015 MKC vehicles built on or before 8/8/2014 and equipped with 2.3L may exhibit a harsh shift or bump felt after the shift caused by the torque converter. Make sure the Adaptive Learning Drive Cycle (Workshop Manual Section 307-01) has been performed before evaluating the vehicle. If the concern is still present, follow this procedure: Vehicle must be at operating temp, Select the ‘S’ shiftbutton and use the manual shift paddles to select 3rd gear. Drive 15 mph, slightly depress accelerator pedal (Light Acceleration to 1500 rpm). At about 22 mph converter will start applying TCC (Torque Converter Clutch), at end of converterclutch apply is where the bump may occur. Repeat this drive procedure 5 times -- If a bump is felt replace the torque converter and use availble service labor times.
