Safety Precautions

Before you begin working on your vehicle, it’s important to take the following safety precautions⁚

• Park your vehicle on a level surface and engage the parking brake.
• Chock the rear wheels to prevent the vehicle from rolling.
• Wear safety glasses and gloves to protect your eyes and hands from hot fluids and debris.
• Do not work under the vehicle unless it is securely supported by jack stands.
• Be aware of any hot components under the hood and take care to avoid burns.

Steps to Change Transmission Fluid

Step 1⁚ Warm Up the Transmission

Start the engine and let it idle for a few minutes. This will warm up the transmission fluid and make it easier to drain.

Step 2⁚ Locate the Drain Plug

The transmission drain plug is located on the bottom of the transmission pan. It is usually a square or hexagonal-shaped plug.

Step 3⁚ Drain the Old Fluid

Place the drain pan under the drain plug and carefully loosen the plug with a wrench. Be careful not to drop the plug into the drain pan.

Step 4⁚ Remove the Pan

Once the old fluid has drained, remove the transmission pan. There may be bolts or clips holding it in place. Be careful not to damage the gasket.

Step 5⁚ Clean the Pan and Magnet

Clean the transmission pan with a wire brush or a rag and remove any debris from the pan. Be sure to clean the magnet that is attached to the pan. This magnet collects metal particles that can wear down the transmission.

Step 6⁚ Install New Gasket

Install a new gasket on the transmission pan. Make sure the gasket is properly seated and that there are no gaps or tears.

Step 7⁚ Reinstall the Pan

Reinstall the transmission pan and tighten the bolts or clips to the proper torque. The torque specs can be found in your owner’s manual.

Step 8⁚ Refill with New Fluid

Remove the transmission dipstick and pour the new fluid into the dipstick tube. Refer to your owner’s manual for the correct amount of fluid to add.

Step 9⁚ Start the Engine and Check Fluid Level

Start the engine and let it idle for a few minutes. Check the fluid level using the dipstick. Add more fluid as needed.

Step 10⁚ Test Drive

Take your vehicle for a test drive and check for any unusual noises or shifting problems.

Conclusion

Changing the transmission fluid in your 1991 Lincoln Town Car is a relatively simple task that can help to extend the life of your transmission. By following these steps, you can ensure that your transmission is properly lubricated and running smoothly.
