1. Preparation:
* Disconnect the battery: This is crucial to prevent accidental short circuits. Disconnect the negative (-) terminal first.
* Gather Tools: You'll likely need a small flat-head screwdriver, possibly a small Phillips head screwdriver (depending on the securing method), and possibly some penetrating oil (like PB Blaster).
2. Removing the Shift Knob:
* Locate the retaining clip or screw: Carefully examine the base of the shift knob. There's usually a small retaining clip or a small screw hidden underneath the knob. This is often hard to see.
* Remove the retaining clip or screw: If it's a clip, use a small flat-head screwdriver to gently pry it open or lift it away from the shift lever. If it's a screw, carefully unscrew it using the appropriate screwdriver. If it's difficult to access or stubborn, applying a bit of penetrating oil to help loosen it can be beneficial. Work slowly and gently to avoid damaging the plastic.
* Lift off the shift knob: Once the clip or screw is removed, the shift knob should simply lift straight up off the shift lever. There might be a slight resistance, but excessive force is a warning sign that something is still attached.
3. Replacing the Plastic Strip:
* Identify the strip's securing method: The plastic strip is likely held in place with clips, adhesive, or some combination. Inspect how it's attached before removing it.
* Carefully remove the old strip: Use a small flat-head screwdriver (or a similar thin, non-marring tool) to gently pry the old strip loose. Be extremely careful not to damage the surrounding parts.
* Clean the area: Before installing the new strip, clean the area thoroughly to ensure proper adhesion (if applicable) and a secure fit.
* Install the new strip: Carefully align and install the new plastic strip, ensuring it's properly seated in its grooves or clips. If it requires adhesive, use a suitable adhesive appropriate for plastic.
4. Reassembly:
* Replace the shift knob: Carefully align the shift knob and push it down onto the shift lever until it firmly snaps into place or the retaining clip/screw can be reattached.
* Reattach the retaining clip or screw: Securely fasten the retaining clip or screw.
* Reconnect the battery: Reconnect the battery's negative (-) terminal.
Important Considerations:
* Take pictures: Before you start dismantling anything, take pictures. This will help you remember how everything goes back together.
* Be gentle: Avoid using excessive force at any point. If something feels stuck, re-examine it before applying more pressure to avoid breakage.
* Consult a repair manual: A repair manual specific to your 1998 Oldsmobile Aurora can provide detailed instructions and diagrams. This is highly recommended, as it will show you the exact location of the retaining clip/screw and any other specific details relevant to your vehicle.
If you're uncomfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. Damaging the shift mechanism could lead to more significant problems.
