Changing the transmission fluid in your 1999 Lincoln Town Car is a crucial maintenance task that can help extend the life of your transmission. Here’s a step-by-step guide to help you get the job done⁚

What You’ll Need⁚

• New transmission fluid (Dexron III or Mercon V) ⏤ Check your owner’s manual for the specific type
• Transmission fluid drain pan
• Torque wrench
• 17mm wrench or socket
• 10mm wrench or socket
• Funnel
• Gloves
• Safety glasses
• Jack and jack stands (optional)

Safety Precautions⁚

• Always work on a level surface.
• Use jack stands if raising the vehicle.
• Wear safety glasses and gloves.
• Never work under a vehicle that is supported only by a jack.
• Transmission fluid is flammable. Keep it away from heat and open flames.

Step-by-Step Instructions⁚

1. Warm Up the Transmission

Start the engine and let it run for a few minutes to warm up the transmission fluid. This will help it flow more easily during the draining process.

2. Locate the Drain Plug

The transmission drain plug is located on the bottom of the transmission pan. It’s typically a 17mm bolt.

3. Drain the Old Fluid

Place the drain pan under the drain plug. Carefully loosen the drain plug and allow the old fluid to drain into the pan.

4. Remove the Pan

Once the fluid has drained, remove the transmission pan. Be careful, as it may still contain some fluid.

5. Clean the Pan and Magnet

Clean the transmission pan thoroughly with a wire brush or a cleaning solvent. Make sure to remove any debris or metal shavings from the magnet inside the pan.

6. Install the New Pan Gasket

If you’re using a new pan gasket, install it according to the manufacturer’s instructions. Make sure the gasket is clean and properly seated before reinstalling the pan.

7. Reinstall the Pan

Carefully reinstall the transmission pan, tightening the bolts evenly. Refer to your owner’s manual for the proper torque specifications.

8. Fill with New Fluid

Locate the transmission dipstick; Remove it and slowly pour the new transmission fluid into the dipstick tube until it reaches the “full” mark on the dipstick. It’s important to add fluid slowly to avoid overfilling.

9. Check the Fluid Level

Start the engine and let it run for a few minutes. Then, shut off the engine and recheck the fluid level. Add more fluid if needed until it reaches the “full” mark on the dipstick. Be sure to check the fluid level while the engine is running and the transmission is warmed up.

10. Drive and Re-Check

Drive the vehicle for a few miles and then re-check the fluid level. If it’s low, add more fluid as needed.

Tips⁚

• It’s a good idea to replace the transmission filter when changing the fluid.
• If you’re unsure about any of these steps, it’s best to consult a qualified mechanic.

By following these instructions, you can successfully change the transmission fluid in your 1999 Lincoln Town Car and help keep your transmission running smoothly for years to come.
