I have an 06 auto Altima ser and haven't had any real issues... Today I was driving on the highway and the tranny kept slipping.... It threw an engine code (p0780) which from what I can tell is a shift malfunction code, has anyone ever got this problem?

I had the same code

My car was acting up before and after that code(it showed the code only for a couple of hours and then it disappeared). The worst was when I was making a turn and going back on the gas it would slam in gear, bad sometimes. I was having a hars downshift in a straight line also when it was a red light and wanted to stop. I ended up replacing the valve body and after that problem solved . The trans oil was normal when I had the problems. Hope this helps... Gl and hope u don't have to replace Anything since the trans service is expensive... Keep me posted if you figure it out.
