However, if you proceed, here's a general overview. This is not a substitute for a factory service manual specific to your 2005 Malibu's transmission type (automatic or manual). You MUST consult that manual for precise procedures, torque specifications, and fluid type/amount.
Tools and Materials You'll Need (Likely):
* New Transmission Fluid: The correct type and amount are crucial. Your owner's manual or a parts store using your VIN will tell you the specific fluid required.
* Transmission Fluid Drain Pan: Large enough to hold several quarts of fluid.
* Torque Wrench: Essential for tightening the drain and fill plugs to the correct specifications.
* Wrench(es): To remove the drain and fill plugs. Sizes will depend on your specific transmission.
* Funnel: To avoid spills when adding new fluid.
* Jack and Jack Stands: To safely lift the vehicle.
* Wheel Chocks: For added safety.
* Gloves: To protect your hands.
* Rags or Shop Towels: For cleaning up spills.
* Optional: Fluid Pump: Makes refilling easier, especially if the fill plug is hard to reach.
General Steps (Consult your service manual for specifics):
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks. Wear safety glasses.
2. Warm Up the Transmission: Run the engine for 10-15 minutes to warm the fluid. This helps it flow more easily.
3. Locate the Drain and Fill Plugs: These are usually located on the bottom and side (or top) of the transmission pan, respectively. Your service manual will show their exact locations.
4. Drain the Old Fluid: Position the drain pan under the drain plug and carefully remove the plug using the appropriate wrench. Let the fluid drain completely. This may take some time.
5. Remove the Transmission Pan (Optional, but recommended): This allows for a more thorough cleaning and inspection of the pan and filter (if applicable). You'll need a socket set and likely a gasket for reinstallation.
6. Replace the Filter (If Applicable): Some transmissions have an easily accessible filter that should be replaced during a fluid change. Refer to your service manual.
7. Clean the Pan: Wipe down the inside of the pan to remove any debris.
8. Reinstall the Pan and Gasket (If Removed): Carefully replace the pan gasket and tighten the pan bolts to the specified torque.
9. Install the Drain Plug: Tighten to the specified torque using a torque wrench.
10. Refill with New Fluid: Using a funnel, add the correct amount of new transmission fluid through the fill plug. Consult your service manual for the correct amount. You may need to add fluid in stages.
11. Check the Fluid Level: Many transmissions have a dipstick, while others require specific procedures (e.g., checking the fluid level through the fill hole). Your service manual will tell you how to check the level correctly. It's often done with the engine running and in Park (or Neutral for manual).
12. Install the Fill Plug: Tighten to the specified torque.
13. Lower the Vehicle: Carefully lower the vehicle using the jack.
14. Test Drive: Test drive the vehicle to ensure proper transmission function. Recheck the fluid level if needed.
Important Considerations:
* Transmission Type: The procedure varies slightly depending on whether you have a 4-speed, 5-speed, or other type of automatic transmission.
* Fluid Type: Use ONLY the recommended transmission fluid for your vehicle. Using the wrong fluid can cause serious damage.
* Torque Specifications: Always use a torque wrench and tighten all bolts to the manufacturer's specifications.
Again, this is a general overview. You absolutely must obtain and consult a repair manual specific to your 2005 Chevy Malibu before attempting this. Failure to do so could result in costly transmission damage. If you're not comfortable, take your car to a qualified mechanic.
