Step 1: Apply parking brake and put shifter in D position. Disconnect Battery. Raise vehicle and secure with jack stands.

Step 2: Remove shifter bezel by gently prying up on both sides and ends. Do NOT pry up in one area!

Step 3: After removing bezel, remove top of center console by removing the (2) nuts at the rear, under arm rest. (Figure 1) .

Step 4: With a flat screwdriver, gently pry up the back' of the center of the console as shown in figure 2 and lift up. Before completely removing, you will need to unplug the switch on the driver's side at the front.

Step 5: Gently squeeze the lower area of the parking brake boot on each side and lift up. The boot will stay on the arm, but will be detached from the main console. Remove the (2) screws at front of console and remove center console (Figure 3) and gently pull out the side panels of console under the main dash area as shown in figure 4 and lift the console up from the rear and remove. NOTE: If there is a power outlet in the rear of the console, be sure to unplug it before removing it!

Step 6: Unplug the plug from the rear passenger side of the factory shifter and pull to the side.

Step 7: From underneath the car use a flat screwdriver and pry out the locking tab on the shifter cable end and at the same time, push up. Then pry the connector off of the shift arm. (Figure 5)

Step 8: Using a small screwdriver press the locking ear on the shifter cable locking clip where it protrudes through the cable support arm and at the same time push up on the small tab shown in figure 6. Do the same to the tab on the upper ear while pulling the cable outward toward the drivers' side. If top tab does not release, then use the screwdriver to gently pry out of arm.

Step 9: From inside remove the (4) nuts that are holding the shifter down and remove shifter.

Step 10: Install new TCI shifter and carefully snug the (4) nuts down in a criss-cross manner, THIS IS VERY IMPORTANT!! Using a torque wrench, torque them down evenly in a criss-cross pattern to 80 inch pounds. If this is not done correctly, damage will occur to shifter! Plug the harness into the shifter.

Step 11: Re-connect battery and turn ignition on and make sure the shift indicator on shifter lights up and cycle thru the gears and put in the D position. From under vehicle, reattach cable to cable support arm.

Step 12: Align shifter cable end with the shift arm and attach. Be careful and do not cycle cable thru the gears when attaching to shifter! If this happens, you must put transmission back into the D (4th gear) position! You can verify this by pulling the shift lever to the rear position. This is PARK. Then push arm forward 3 clicks. You should feel the detents in the transmission when you do this.

Step 13: Put shifter in PARK position and re-connect battery cables. Tum ignition key on and make sure the shift indicator illuminates an amber color in Park only. Now you can lower vehicle.

Step 14: Re-install center console pieces and shifter bezel in reverse order of removal in Steps 2-5.
