Shift Control Cable

The replacement process for shift cables starts by setting the steering column shift lever into park position then lifting the vehicle. You should detach the clips between cable and floor panel reinforcement while keeping the transmission manual shaft in mechanical park. The first step consists of disconnecting the bracket retainer from the cable and eliminating the Transfer Case cable clip when present. Disconnect the Shift Cable end by removing it from the transmission range selector lever ball stud and then depress the cable tangs before pulling it out from the bracket. Lower the vehicle into position with the steering lever in park and take out the driver seat before pulling back the carpet material and driver space insulation. First untie the instrument panel knee bolster then loosen the retainer that connects the cable to the steering column before disconnecting the cable end from the steering column ball stud. Firmly pressing the tangs will allow you to remove the cable from the steering column bracket while preventing avoidable twists or bends in the Shift Cable. Take out the cable both from the support and remove the grommet installed in the floor panel. The cable must enter the vehicle while you install the floor panel grommet before checking that the cable remains untwisted and unbent. Position the Shift Cable onto the support while keeping the transmission manual shaft lever at mechanical park then connect the cable to the steering column bracket with full tang contact achieved. Position the cable end to the steering column ball stud then fasten it with the retainer. Install the carpet material along with the insulation and return the driver seat and instrument panel knee bolster to its original position. Gently lift the vehicle once more while performing proper alignment on the cable before securing it to its bracket followed by attaching the Shift Cable end to the transmission range selector lever ball stud and finishing by attaching the cable clip on the Transfer Case if present. After securing the cable to the bracket with the retainer, reattach its clips to the floor panel reinforcement while the vehicle remains in the raised position. A proper transmission shift test should be performed to confirm operational functionality. Further adjustments to the cable should also be done when obtaining all gear positions becomes challenging.

Remove the range selector cable heat shield bolts and the heat shield itself, ensuring the transmission manual shaft is in mechanical park.
