My Saturn stopped pulling when stopped, thankfully at our driveway. It would not go forward and the engine just revved. It would pull in reverse but not in drive. Attempted the manual mode but still did not pull and did not show gear indication on dash. Upon several times turning on and off it started pulling. The dealership could not recreate. Program update to tcm and $300 later we left. One month later the transmission slipping so bad it almost stalled in intersections creating a potentially dangerous scenario. We took it to the dealership the next day to have them say we need a new transmission. The dealership was unaware of a recall on the news regarding a transmission problem for the Auras but not for this problem or model. This needs to be a recall since it is a safety hazard. Please consider a recall for this problem.
Entering highway and lost gear - got 2nd back to be able to drive off the highway. Stopped for a train: could not reverse. Lost gear: no forward or backwards on a two line bridge. Towed to a shop: transmission control module malfunction. Able to get to a dealer: nobody wanted to hear what happened - nobody able to tell when car would be even checked for problems. That was a serious safety issue: what if the vehicle stalled in a middle of a intersection instead of on a slow moving bridge. Dealer was not interested in hearing what I found about transmission issues and NHTSA investigation regarding 2007 Auras.
