It seems that quite often when I shift to drive from park the vehicle does not move until I shift to 3rd. Also when I shift to 1st manually the indicator on the cluster does not always indicate 1st. I adjusted the cable per the fsm and that seemed to make it a little better, but not much. Also, if I downshift manually leaving it in each gear for a few seconds it goes into first almost every time. I am also getting PCM codes 1520 and 1527. Any advice will be appreciated.
