Focus 2013 TDCi (Diesel) 2lt. Automatic. Current issues with gear changes especially clunk and jerk when in 1st or reverse also tacho fluctuates. Have had diagnostic done by automatic transmission specialist and faults were shown for multiple engine issues, no transmission faults showing. Advise was to have any TCM and PCM software updates done then diagnose again and action issues. Does anyone know what software updates are available for this vehicle.
