2000 GMC C3500 Automatic Transmission Shifter Cable

You should remove the cable retainer from the transmission mounting bracket, squeeze the cable retainer while pulling the cable towards the rear of the vehicle, disconnect the cable end from the transmission shift ball stud, position the transmission shift to PARK (P) and rotate the shift clockwise until the lever reaches the full clockwise stop position.

You should push the white lock button on the range and select the lever cable end out. This will free the metal core to adjust the body which is inside the cable end. You can not push the white lock button completely out and inspect the metal core adjust body on the cable end for dirt or debris. If the travel of the metal core adjust body remains restricted after the cleaning, you should replace the cable assembly.

You should make sure that the steering column transmission shift lever is in Park (P), install the carpet and the carpet retainers on the driver's side and route the range select lever cable under the fuel lines.
