Here's a general outline. Crucially, this is not a substitute for a detailed repair manual. Improper installation can lead to shifting problems or damage to your transmission.
1. Preparation:
* Consult a Repair Manual: This is absolutely essential. A Haynes or Chilton manual for your specific vehicle will give you detailed diagrams, torque specifications, and step-by-step instructions.
* Gather Tools: You'll likely need screwdrivers (Phillips and flathead), wrenches (metric), possibly pliers, and maybe a socket set. A transmission jack might make things easier, but isn't strictly necessary.
* Safety First: Disconnect the negative battery terminal before starting any work to prevent accidental shorts.
* Vehicle Position: Park the car on a level surface, engage the parking brake firmly, and chock the wheels.
2. Accessing the Shifter Cable:
* Locate the Cable: Your repair manual will show you the exact location of the shifter cable(s) at both the transmission and the shifter lever. Generally, you'll find them under the hood and possibly under the car, near the transmission.
* Remove Obstructions: You'll likely need to remove some plastic panels or other components to gain access. The manual will guide you through this.
3. Disconnecting the Old Cable:
* Transmission End: This will typically involve removing clamps or fasteners securing the cable to the transmission linkage. Pay close attention to how it's attached – take pictures if necessary.
* Shifter Lever End: Disconnect the cable from the shifter lever inside the car. This often involves removing a retaining clip or bolt.
4. Installing the New Cable:
* Reverse the Removal Process: Carefully install the new cable, ensuring it's correctly routed and seated in all its attachment points. Refer to the repair manual diagrams meticulously. Pay attention to any adjustment mechanisms on the cable.
* Check for Proper Movement: Before tightening everything up, check that the shifter moves freely and smoothly throughout its range. Make sure the cable isn't binding or kinking anywhere.
5. Reassembly and Testing:
* Reconnect everything: Reinstall all removed components in the reverse order of removal.
* Tighten all fasteners: Use the correct torque specifications from your repair manual.
* Reconnecting Battery: Reconnect the negative battery terminal.
* Test the Shifter: Start the engine and carefully shift through all the gears. Make sure shifting is smooth and that all gears engage correctly.
Important Considerations:
* Transmission Type: The process will vary slightly depending on whether you have an automatic or manual transmission.
* Cable Type: There may be more than one shifter cable (e.g., one for park/neutral and one for the other gears).
* Adjustment: Some shifter cables require adjustment after installation to ensure proper shifting. Your repair manual will explain how to do this.
Again, this is a general overview. A repair manual specific to your 1995 Buick Century is crucial for safe and successful completion of this repair. If you're uncomfortable performing this repair yourself, it's best to take your car to a qualified mechanic. Improper installation could lead to significant damage to your transmission.
