The 1990 Lincoln Town Car, known for its luxurious ride and powerful engine, can sometimes be plagued by transmission issues. This guide provides comprehensive information on common 1990 Lincoln Town Car Transmission Problems, diagnosis, and solutions, helping owners and mechanics alike keep these classic cars running smoothly.
Understanding Your 1990 Lincoln Town Car Transmission
The 1990 Lincoln Town Car typically features a Ford AOD (Automatic Overdrive) transmission. This 4-speed automatic transmission is generally reliable but can develop issues over time, especially with high mileage and lack of proper maintenance. Knowing the common problems associated with this transmission can help you pinpoint the issue and get your car back on the road.
Common 1990 Lincoln Town Car Transmission Problems
Some of the most common transmission problems include slipping between gears, harsh shifting, delayed engagement, fluid leaks, and a complete failure to shift. These problems can stem from various causes, ranging from low transmission fluid to more severe internal damage.
- Slipping Between Gears: This often feels like the car is momentarily losing power and then regaining it. This can be caused by low fluid, worn clutches, or a faulty valve body.
- Harsh Shifting: This can manifest as a jarring or banging sensation when the transmission changes gears. This could be due to a malfunctioning shift solenoid, low fluid, or a problem with the transmission control module (TCM).
- Delayed Engagement: A noticeable delay between shifting into gear and the car actually moving can be a sign of low fluid, a failing torque converter, or a problem with the valve body.
- Fluid Leaks: Transmission fluid leaks should never be ignored. A leak can quickly lead to low fluid levels and catastrophic transmission failure. Check for leaks around the pan gasket, cooler lines, and the front seal.
- Failure to Shift: This is a serious issue and often indicates major internal damage within the transmission. This could require a complete rebuild or replacement.
Diagnosing 1990 Lincoln Town Car Transmission Issues
Proper diagnosis is crucial for effective repair. Start by checking the transmission fluid level and condition. Low fluid or burnt fluid (dark color and burnt smell) can indicate several problems. Next, scan the car’s computer for any diagnostic trouble codes (DTCs) related to the transmission. These codes can provide valuable clues about the nature of the problem. A professional mechanic with experience in diagnosing 1990 Lincoln Town Car transmissions can help identify more complex issues.
