Installation Procedure

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2003 GMC Savana Special, 2003 GMC Savana Camper Special, 2003 GMC Savana, 2003 Chevrolet RV Cutaway, and 2003 Chevrolet Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
  1. Carefully slide a new selector shaft seal (1) over the selector shaft (2) with the wide face of the steel case facing outward. Position the seal so that it is starting to enter the seal bore.
  2. Obtain J 43909  and remove the inner sleeve so that the tool will slide over the selector shaft.
  3. Slide the J 43909  into position so that the end of the tool contacts the seal being installed. Use a mallet to strike the J 43909  and drive the new seal into the seal bore until it is seated at the bottom of the bore.
  4. Install the PNP Switch. Refer to Park/Neutral Position Switch Replacement .
