The transmission cable bushing is a small but important part of your 1990 Lincoln Town Cars transmission system. It helps to keep the transmission cables in place and prevents them from wearing out prematurely. Over time, the bushing can become worn or damaged, which can lead to shifting problems. If you notice any shifting problems, its important to check the transmission cable bushing and replace it if necessary.
Tools and Materials
- Socket set
- Wrench set
- Phillips screwdriver
- Flathead screwdriver
- New transmission cable bushing
- Grease
- Shop towels
Procedure
- Locate the transmission cable bushing. The bushing is located on the transmission, near the shift linkage. It is a small, rubber or plastic piece that fits over the transmission cable.
- Remove the old bushing. Using a socket wrench or wrench, loosen the nut that holds the transmission cable in place. Once the nut is loose, you can remove the old bushing.
- Install the new bushing. Grease the new bushing with grease and install it over the transmission cable. Make sure that the bushing is properly seated.
- Tighten the nut. Tighten the nut that holds the transmission cable in place. Make sure that the nut is tight, but do not overtighten it.
- Test the transmission. Once the new bushing is installed, test the transmission to make sure that it is shifting properly. If you are still experiencing shifting problems, you may need to have the transmission inspected by a qualified mechanic.

Understanding the Importance of the Transmission Cable Bushing
The transmission cable bushing might seem like a small and insignificant part, but its role in ensuring smooth and reliable gear changes is crucial. Think of it as a protective shield for the transmission cable. It prevents wear and tear on the cable, allowing it to move freely and engage the transmission properly. A worn or damaged bushing can lead to several issues⁚
- Shifting Problems⁚ The most noticeable symptom is difficulty shifting gears. The car might hesitate or refuse to shift into the desired gear, resulting in a rough ride and potential damage to the transmission.
- Slipping Gears⁚ In some cases, the transmission might slip out of gear, especially under load or during acceleration. This can be dangerous, particularly when attempting to pass or accelerate quickly.
- Increased Wear and Tear on the Transmission⁚ A damaged bushing can cause the transmission cable to bind or stick, putting undue stress on the transmission itself. This can lead to premature wear and tear, eventually requiring costly repairs.
Identifying a Worn or Damaged Bushing
While its not always easy to identify a worn bushing visually, there are some signs that can indicate a problem⁚
- Visible Cracks or Tears⁚ If you can access the bushing, look for any cracks, tears, or signs of excessive wear on the rubber or plastic material.
- Sticking or Binding⁚ If you try to move the transmission cable by hand, you might feel resistance or notice that it doesnt move freely. This is a strong indicator that the bushing is worn.
- Shifting Problems⁚ As mentioned earlier, difficulty shifting gears, slipping gears, or any unusual shifting behavior can be a sign of a worn bushing.
Preventive Maintenance
While replacing the transmission cable bushing is a straightforward repair, its always better to prevent problems before they arise. Here are some preventive maintenance tips⁚
- Regular Inspections⁚ Inspect the bushing during routine maintenance checks, especially if you notice any shifting issues.
- Lubrication⁚ Lubricate the bushing with grease to reduce friction and wear. This can help extend its lifespan.
- Avoid Aggressive Driving⁚ Aggressive driving habits can put undue stress on the transmission system, including the bushing.
By following these tips and replacing the bushing when necessary, you can ensure the smooth and reliable operation of your 1990 Lincoln Town Cars transmission system for years to come.
