Here's a general outline of the process. This is NOT a complete, step-by-step guide, and specific details may vary slightly depending on your exact model. Always consult a repair manual specific to your 1998 Saturn SL2 5-speed for precise instructions, diagrams, torque specifications, and part numbers. A Haynes or Chilton manual would be a good investment.
Steps (General):
1. Preparation: Disconnect the battery negative terminal. Gather your tools: sockets (various sizes), wrenches, screwdrivers (Phillips and flathead), jack stands, wheel chocks, penetrating oil (like PB Blaster), rags, and your new shifter linkage assembly.
2. Access: Jack up the car and securely support it on jack stands. Remove the necessary underbody shields or trim panels to gain access to the transmission and shifter linkage.
3. Disconnect the Linkage: This is the most crucial and potentially tricky part. You'll need to disconnect the linkage from several points:
* Shift lever to linkage: This usually involves removing bolts or cotter pins connecting the shift lever inside the car to the linkage rod that runs underneath. You'll likely need to access this from inside the car as well as under the car.
* Linkage to transmission: There will be connections at the transmission itself. These are typically ball joints or similar connectors. Penetrating oil may be necessary to loosen seized connections. Take note of the linkage arrangement before disconnecting to ensure correct reassembly.
4. Remove the Old Linkage: Once disconnected, carefully remove the old linkage assembly. Pay close attention to how everything is connected; take pictures or make detailed notes if necessary.
5. Install the New Linkage: Install the new linkage assembly, reversing the removal process. Ensure all connections are secure and properly aligned.
6. Reconnect the Linkage: Reconnect the linkage at the transmission and the shift lever, ensuring proper alignment.
7. Test: Lower the car, reconnect the battery, and carefully test the shifting action. Check for smooth shifts in all gears and ensure no binding or unusual noises. If there are any issues, recheck all connections.
8. Adjustments (if needed): Some linkage adjustments may be required to achieve optimal shifting feel. Your repair manual should provide guidance on this. This often involves adjusting the linkage rods to achieve proper engagement in each gear.
Important Considerations:
* Penetrating Oil: Use penetrating oil liberally on any bolts or connections that seem stuck or rusty. Allow sufficient time for it to penetrate before attempting to loosen them.
* Alignment: Proper alignment is crucial for smooth shifting. Pay very close attention to how everything fits together.
* Repair Manual: A repair manual is highly recommended to avoid mistakes and potential damage.
* Safety First: Always prioritize safety. Use jack stands properly, work in a well-lit area, and never work under a car supported only by a jack.
This is a complex procedure, and attempting it without experience and proper tools can lead to damage. If you're not comfortable with this type of repair, it's best to take your car to a qualified mechanic.
