That said, here's a general overview of the process. Remember, this is NOT a substitute for your owner's manual:
Tools and Materials You'll Need:
* New Transmission Fluid: The correct type and amount are crucial. Your owner's manual will specify the type (e.g., Mercon V) and quantity. Buy more than you think you'll need; it's better to have extra.
* Transmission Fluid Pan: A new pan is often recommended, as the old one may have accumulated debris. A gasket is also usually necessary.
* Drain Pan: A large capacity drain pan to catch the old fluid.
* Socket Wrench Set: You'll need sockets to remove the drain plug and the transmission pan.
* Wrench for Drain Plug: The size will vary.
* Torque Wrench: Essential for tightening the drain plug and pan bolts to the correct specifications. Over-tightening can damage the transmission.
* Funnel: For adding new fluid.
* Jack and Jack Stands: Safely lift the car and support it. NEVER work under a car supported only by a jack.
* Wheel Chocks: For added safety.
* Gloves: To protect your hands from the old transmission fluid.
* Rags or Shop Towels: To clean up spills.
* Optional: Transmission Filter: Some transmissions have a filter; check your owner's manual. If it does, you'll need a new filter.
Procedure (General Steps - Always Refer to Your Owner's Manual):
1. Safety First: Engage the parking brake, chock the wheels, and properly support the vehicle on jack stands.
2. Locate the Transmission Pan: It's usually located on the bottom of the transmission.
3. Warm Up the Transmission: Run the engine for 10-15 minutes to warm the fluid. This will make it flow more easily.
4. Drain the Old Fluid: Carefully position the drain pan under the transmission pan. Remove the drain plug and let the fluid drain completely. This may take some time.
5. Remove the Transmission Pan: Once drained, remove the transmission pan bolts carefully. The pan may contain some fluid, so be prepared.
6. Replace the Filter (if applicable): If your transmission has a filter, replace it now.
7. Clean the Pan: Clean the old transmission pan thoroughly if you're reusing it. A new pan is generally recommended.
8. Install New Gasket: If reusing the pan, install a new gasket.
9. Reinstall the Transmission Pan: Carefully reinstall the transmission pan, ensuring the gasket is properly seated. Tighten the bolts to the manufacturer's specified torque.
10. Refill the Transmission: Locate the transmission fill tube (often on the side or top of the transmission). Use a funnel to add the correct amount of new transmission fluid as specified in your owner's manual.
11. Check the Fluid Level: Most automatic transmissions have a dipstick. Check the fluid level and add more fluid as needed. The proper level and temperature are critical. Some newer transmissions may require a scan tool to check level.
12. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
13. Test Drive: Take the car for a short test drive to ensure the transmission is functioning properly.
14. Recheck Fluid Level: After the test drive, recheck the transmission fluid level when it's at operating temperature.
Important Considerations:
* Type of Fluid: Using the incorrect transmission fluid can severely damage your transmission.
* Torque Specifications: Using a torque wrench to tighten bolts to the correct specifications is crucial to prevent leaks and damage.
* Fluid Capacity: Adding too much or too little fluid can cause problems. Consult your owner's manual for the correct amount.
This is a general overview. Always consult your 2006 Mustang GT owner's manual for specific instructions and torque specifications. If you are uncomfortable performing this task yourself, take your car to a qualified mechanic. Improperly changing your transmission fluid can lead to significant and expensive repairs.
