Hello, I am new here, I have a 2014 diesel cruze with 126,000 miles. A friend helped me replace the timing belt and water pump. Once it was put back together it fired right up without a issue. Once it was off the lift and restarted the Stabili trak and TCS needs service lit up. The tachometer also does not work, as well as when it is put into gear it the transmission shifts very harshly and once underway the automatic transmission does not shift out of first. Does anyone have any idea what could have gone wrong and what I need to do to fix it?
