Important Note: The 2006 Mustang's transmission fluid type is crucial. Using the incorrect fluid can severely damage the transmission. Always check your owner's manual for the correct type and specification of transmission fluid.
Automatic Transmission:
This is more complex and generally requires specialized tools. It's often recommended to have a professional mechanic perform this service.
* What you'll need: New transmission fluid (the correct type and amount specified in your owner's manual), a transmission fluid drain pan, a wrench for the drain plug, a funnel, possibly a pump for refilling (depending on the transmission type), and possibly a torque wrench. You may also need a scanner to check transmission fluid temperature.
* Steps (General Outline - Consult your manual for specifics):
1. Warm up the transmission: Run the engine until the transmission fluid reaches operating temperature. Check your owner's manual for the recommended temperature.
2. Locate the drain plug: This is usually on the bottom of the transmission pan.
3. Drain the fluid: Carefully position the drain pan and remove the drain plug. Let the fluid drain completely. This can take a considerable amount of time.
4. Remove the transmission pan: This usually involves removing several bolts. Be prepared for some fluid spillage.
5. Clean the pan and filter: Inspect the pan for any debris or damage. Replace the transmission filter (if applicable and accessible). Clean the pan thoroughly.
6. Replace the transmission pan gasket: Use a new gasket when reinstalling the pan.
7. Reinstall the transmission pan: Tighten the bolts evenly and to the correct torque specification (consult your manual).
8. Refill the transmission: This is often the trickiest part. You might need to use a pump to add the fluid through the dipstick tube or a filler port. Consult your manual to find the correct fill method and fluid capacity.
9. Check the fluid level: With the engine running and the transmission in park (or neutral), check the fluid level using the dipstick. Add more fluid if needed.
10. Test drive: Test drive the vehicle to ensure proper operation. Recheck the fluid level.
Manual Transmission:
This is typically a simpler process.
* What you'll need: New gear oil (the correct type and amount specified in your owner's manual), a drain pan, a wrench for the drain plug, a funnel, and possibly a torque wrench.
* Steps (General Outline - Consult your manual for specifics):
1. Warm up the transmission: Let the car run for a few minutes to warm the oil.
2. Locate the drain plug: This is usually on the bottom of the transmission case.
3. Drain the fluid: Carefully position the drain pan and remove the drain plug. Let the fluid drain completely.
4. Locate the fill plug: This is usually on the side of the transmission case.
5. Refill the transmission: Use a funnel to add the correct amount of new gear oil. Consult your owner's manual for the correct fill quantity.
6. Check the fluid level: Most manual transmissions have a fill plug at the correct level. When oil starts to come out of this hole, you have filled it to the correct level. Replace the plug.
7. Test drive: Test drive the vehicle to ensure proper operation.
Again, this is general information. Always consult your 2006 Ford Mustang's owner's manual for the specific procedures, fluid type, and quantities for your vehicle. If you are not comfortable performing this task yourself, take it to a qualified mechanic.
