How to Change the Transmission Filter on a 2003 Lincoln Town Car

Changing the transmission filter on a 2003 Lincoln Town Car is a relatively simple task that can be done by most DIY mechanics. Here’s a step-by-step guide to help you complete the job⁚

What You’ll Need

• New transmission filter
• New transmission fluid (approximately 10 quarts)
• Drain pan
• Torque wrench
• Socket set (including 10mm‚ 13mm‚ and 17mm sockets)
• Wrench (for removing the filter housing bolts)
• Gloves
• Safety glasses
• Rag
• Jack and jack stands (optional‚ but recommended)

Step-by-Step Instructions

1. Prepare the Vehicle

Park the vehicle on a level surface and engage the parking brake. If you’re using jack stands‚ raise the vehicle and place the stands securely under the frame rails.

2. Locate the Transmission Filter

The transmission filter is located on the passenger side of the transmission‚ near the rear of the vehicle. It’s a rectangular‚ metal housing with a large bolt in the center.

3. Drain the Transmission Fluid

Place the drain pan under the transmission drain plug‚ which is located on the bottom of the transmission. Use a 17mm socket to loosen and remove the drain plug. Allow the fluid to drain completely.

4. Remove the Filter Housing

Using a 10mm socket‚ remove the bolts holding the filter housing to the transmission. There are usually four bolts in a rectangular pattern. Once the bolts are removed‚ gently pry the filter housing off the transmission. Be careful not to damage the filter housing or the transmission.

5. Install the New Filter

Inspect the filter housing for any cracks or damage. If the housing is damaged‚ replace it with a new one. Place the new filter inside the housing‚ ensuring it’s properly seated.

6. Reinstall the Filter Housing

Align the filter housing with the transmission and install the bolts you removed earlier. Tighten the bolts evenly using a torque wrench to the specifications outlined in your vehicle’s service manual.

7. Replace the Drain Plug

Reinstall the transmission drain plug and tighten it securely. Use a torque wrench to tighten the plug to the proper specifications.

8. Fill the Transmission with New Fluid

With the drain plug and filter housing secured‚ carefully pour the new transmission fluid into the transmission fluid dipstick tube. Refer to your vehicle’s service manual for the proper fluid fill amount.

9. Check the Fluid Level

Once you’ve added the fluid‚ start the engine and allow it to idle for a few minutes. Check the fluid level again using the dipstick. If the level is low‚ add more fluid until it reaches the “full” mark on the dipstick.

10. Test Drive

Take the vehicle for a short test drive to ensure the transmission is shifting properly. If there are any issues‚ check the fluid level again and make sure the filter housing is properly secured.

Important Notes

• Always use the correct transmission fluid for your vehicle. Consult your owner’s manual for the recommended fluid.
• When working with transmission fluid‚ wear gloves and safety glasses to protect yourself from spills and splashes.
• If you’re uncomfortable performing this task‚ consult a qualified mechanic.
