2008 scion XB in minnesota i have noticed if the car is not warm it will not shift into 4th gear until it reaches proper temp. then 3 weeks ago it would not shift into 4th gear, pulled over checked fluid and was just below the add, got to town and added some but still did not shift into 4th gear. went to O'Rileys and scanned it had 2 codes P0328 and P0327 took it to a small shop that does transmissions to have them scan it and to see if maybe O'Rileys just could not read it and nope just those 2 codes. any help would be appreciated. Note, i got the knock sensor but not the gaskets for it yet but they are ordered.
