Ok so the trans wont shift into over drive. I have scanned codes and got a p0700 and p1492 code. So the other day while driving I decided to pop the trans into neutral, turn off the key and turn it back on and put the trans back into drive and it shifted itself into overdrive. When doing this as long as you are over 45 mph it will stay in overdrive. Anything lower than that it hard shifts back into 3rd. Any ideas?
