I was driving down the street and the car stopped going I let it sit for awhile and it went a little then stopped I had to tow it to a transmission shop and they said that water got into transmission because of the way the water flows from the radiator to trans to cool it. Transmission fluid was mixed in water and water in transmission so I had to replace both and clean entire system out. I also am having problems with my headlights staying on at night they keep going on and off while I am driving I see this too is an ongoing problem and a safety issue.
