I have a 2005 Aveo and my hold light has been coming on while driving randomly. Ill be on the interstate going around 60 mph and the hold starts flashing along with the check engine light. So it won't change gears when it happens so I have to pull over and cut the engine off then its fine. Not sure why this is happening. I did have a new motor put in about 1,000 miles ago. The engine was used but low miles.
Any feedback? I'm a woman so any advise would be greatly appreciated.
