OK guys not sure what is going on but any help would be nice. I was getting on the Highway and got on the gas. When I let off the car down shifted really hard and then the check engine light turned on. The car went into neutral but still showed it was in Drive. Once i got to about 20 it then went back into gear and everything was fine but the check engine light was on. The next day i was going to take the car in to get it checked out the light was out. Well yesterday wife was doing the same thing ans it happen again only it didn't go into neutral just the light turned on. Any advice would be great before i take it into the shop. It is a 04 limited autostick. Thanks agian
