Hi
My car Legacy GT 5eat has been weird. It runs and at some times you can hear a clank sound on the back part and the car shifts to a higher gear. usually happen when shifting from 1 to 2. Scanned the car and had the following codes P0817, P0756, P0766, P0763 and P0700. if i turn the car off it works again fine for a little time. I havent used the car for almost 2 years now and i want to fix it.
Car had Mobil 1 AT oil and is full.
