The transmission tc-sst is failing on the 2009 ralliart from Mitsubishi the gears go crazy on me and jump around and gears are slipping and getting stuck. Other people with the same car have experienced the same thing I think it should be re-call to get this fixed. It can cause a major accident on the highway which it almost did for me.
