I have a 1996 Kia Sephia with 1.8 liter engine and has a automatic transaxle. It's been running very good till one day, I parked and the next morning, it was not be moving at all. The engine starts good but doesn't seem to engage in reverse or drive. What happened? Could it be a loose connection? The levers are shifting but still nothing. Anyone have an answer? Fluid is up to level and checked all the wires and they seem to be OK.
