Transmission Related:
* Rebuilt Transmission Quality: The biggest concern is the quality of the rebuild. Was it done by a reputable shop with quality parts? A poorly rebuilt transmission can fail quickly. Look for documentation detailing the work done, parts used, and warranty offered. If there's no documentation, be wary.
* Transmission Slipping: Pay close attention to how the transmission shifts. Any slipping, delayed engagement, or harsh shifts are red flags indicating potential problems. Test it thoroughly, including acceleration from various speeds and driving in different conditions (hills, city driving).
* Fluid Leaks: Check regularly for transmission fluid leaks. Any sign of leakage is a serious issue that needs immediate attention.
* Transmission Cooler Lines: These can deteriorate and leak, causing transmission failure. Inspect them carefully.
* Warranty: How long is the warranty on the rebuilt transmission? A shorter warranty period might indicate a lack of confidence in the rebuild.
Windstar Specific Issues (Beyond the Transmission):
* Rear Suspension: Windstars are known for rear suspension issues, particularly the rear struts and shocks. Pay attention to any knocking or bouncing.
* Electrical Problems: Being a 1999 model, expect some electrical gremlins. Check all lights, power windows, and other electrical components. The wiring harness can be prone to wear and tear.
* Cooling System: Regular maintenance is crucial for the cooling system. Check for leaks and ensure the coolant is in good condition. Overheating can damage the engine and transmission.
* Rust: Depending on where the vehicle was driven, rust could be a significant problem, particularly in the undercarriage.
* Intake Manifold: Some Windstars have issues with the intake manifold gasket. Listen for any vacuum leaks or rough idling.
Before buying:
* Get a pre-purchase inspection: This is absolutely crucial, especially with a rebuilt transmission. A qualified mechanic can inspect the vehicle thoroughly and identify any potential problems.
* Check the vehicle history report: This will reveal any accidents or major repairs.
* Test drive extensively: Pay close attention to how the car drives, shifts, and handles.
In summary, while 75,000 miles might seem low, the rebuilt transmission is a major risk factor. Thorough inspection and a pre-purchase inspection are vital to avoid costly repairs down the line. Don't be afraid to walk away if you're uncomfortable with the vehicle's condition or lack of documentation.
