That said, here's a general overview of the procedure. This is not a complete, step-by-step guide, and you should consult a repair manual specific to your 2002 Mustang GT for detailed instructions and torque specifications.
Tools You Will Need:
* Transmission Jack: Essential for safely supporting the transmission.
* Jack Stands: For added safety.
* Torque Wrench: Absolutely crucial to avoid damaging bolts.
* Drain Pan: Large capacity.
* Funnel: Wide-mouth, preferably flexible.
* Wrench(es): Various sizes to fit transmission pan bolts, drain plug, etc. (Check your manual)
* New Transmission Filter: Specific to a 4R70W transmission.
* New Transmission Fluid: The correct amount and type (consult your owner's manual; Mercon V is commonly recommended but check your manual).
* Rags or Shop Towels: For cleanup.
* Gloves: Protect your hands.
* Repair Manual: A MUST for detailed instructions, torque specifications, and diagrams.
General Steps (Highly Simplified):
1. Safety First: Disconnect the negative battery terminal. Raise the vehicle securely on jack stands. Never work under a vehicle supported only by a jack.
2. Locate the Transmission Pan: The pan is usually located on the bottom of the transmission.
3. Drain the Fluid: Carefully remove the transmission pan drain plug, letting the fluid drain completely into your drain pan. Be prepared – it will be hot!
4. Remove the Transmission Pan: Once the fluid has drained, carefully remove the transmission pan bolts. The pan may be heavy and contain some remaining fluid.
5. Replace the Filter: The filter is usually located inside the transmission pan. Replace it with a new one.
6. Clean the Pan: Clean the transmission pan thoroughly, removing any debris or old gasket material.
7. Install a New Gasket: Install a new transmission pan gasket (usually included with a new filter kit).
8. Reinstall the Pan: Carefully reinstall the transmission pan and tighten the bolts to the manufacturer's specified torque.
9. Refill the Transmission: This is the trickiest part. You'll need to add fluid through the filler tube (usually located on the side or top of the transmission). You will likely need to add fluid, then run the engine briefly with the car in park, checking the fluid level and adding more as needed. Consult your repair manual for the proper method of checking the transmission fluid level (often involves checking the fluid temperature and using a dipstick). You'll likely need to add fluid in stages, running the engine briefly each time.
10. Lower the Vehicle: Once the fluid level is correct, carefully lower the vehicle.
11. Check for Leaks: Check for any leaks around the transmission pan and drain plug.
12. Reconnect the Battery Terminal.
Crucial Considerations:
* Fluid Type: Use ONLY the correct transmission fluid specified in your owner's manual. Using the wrong fluid can severely damage your transmission.
* Torque Specifications: Use a torque wrench and tighten all bolts to the manufacturer's specifications. Over-tightening can strip threads, while under-tightening can lead to leaks.
* Fluid Temperature: Transmission fluid temperature affects its level. Refer to your manual for the correct procedure and temperature.
* Professional Help: If you are uncomfortable with any part of this process, take your vehicle to a qualified mechanic. The cost of a professional transmission service is far less than the cost of transmission repair or replacement due to a mistake.
This is a simplified overview. Always consult a repair manual specific to your 2002 Mustang GT for detailed, step-by-step instructions and torque specifications. Incorrectly performing this procedure can lead to serious transmission damage. If you're unsure about any step, err on the side of caution and seek professional help.
