Keeping your Town Car’s transmission in top condition is crucial for a smooth and enjoyable driving experience. Regular transmission fluid changes are essential, but sometimes a more thorough flush is necessary to remove contaminants and ensure optimal performance. This guide will walk you through the process of flushing your Town Car’s transmission, equipping you with the knowledge and confidence to tackle this task yourself.
Why Flush Your Transmission?
Over time, transmission fluid degrades, losing its lubricating properties and becoming contaminated with debris. This can lead to⁚
- Rough shifting
- Slipping gears
- Transmission overheating
- Reduced fuel efficiency
- Potential transmission failure
A transmission flush removes old fluid and replaces it with fresh, clean fluid, restoring optimal performance and extending the life of your transmission.
What You’ll Need
- New transmission fluid (consult your owner’s manual for the recommended type and quantity)
- Transmission flush kit (available at most auto parts stores)
- Drain pan
- Torque wrench
- Wrench set
- Gloves
- Safety glasses
- Clean rags
- Jack and jack stands
- Optional⁚ Transmission fluid cooler flush kit
Step-by-Step Guide
1. Preparation
- Park your Town Car on a level surface and engage the parking brake.
- Locate the transmission fluid pan (typically near the bottom of the transmission).
- Place the drain pan underneath the pan to catch the old fluid.
- Warm up the transmission by driving for a few minutes. This will help thin the fluid and make it easier to drain;
2. Draining the Old Fluid
- Locate the transmission fluid drain plug and loosen it using a wrench. Be careful not to strip the plug.
- Allow the old fluid to drain completely into the drain pan.
- Once the fluid has stopped draining, tighten the drain plug securely using a torque wrench.
3. Flushing the Transmission
- Connect the transmission flush kit to the transmission cooler lines (usually located near the radiator). Consult your owner’s manual or a repair manual for specific instructions.
- Start the engine and allow it to idle.
- Follow the instructions provided with the flush kit. Typically, you’ll need to run the engine while the kit circulates new fluid through the transmission.
- Monitor the color of the fluid draining from the transmission. Once the fluid runs clear, the flush is complete.
4. Topping Off with New Fluid
- With the engine running, slowly add new transmission fluid through the dipstick tube until the fluid level reaches the “full” mark on the dipstick.
- Check the fluid level again after driving the car for a few minutes. Add more fluid if necessary.
5. Cleaning Up
- Dispose of the old transmission fluid properly according to your local regulations.
- Clean up any spills or leaks.
- Inspect the transmission for any leaks or damage.
Additional Tips
- If you’re not comfortable performing a transmission flush yourself, take your Town Car to a qualified mechanic.
- Use the correct type of transmission fluid recommended by your owner’s manual. Using the wrong type can damage your transmission.
- Always wear safety glasses and gloves when working with transmission fluid. It can be harmful to your skin and eyes.
- If your transmission is exhibiting significant problems, a flush may not be enough to resolve them. You may need to have your transmission inspected by a mechanic.
By following these steps and taking the necessary precautions, you can successfully flush your Town Car’s transmission and ensure its continued smooth operation. Remember to consult your owner’s manual for specific instructions and recommendations for your vehicle.
