The 2002 Ford Explorer is equipped with a 5-speed automatic transmission, specifically the 5R55W model. This SUV, known for its versatility and capability, has garnered attention for its transmission performance, which can be a concern for potential buyers and current owners alike.

Overview of the 5-Speed Automatic Transmission

The 5R55W transmission was designed to provide smooth shifting and reliable performance. However, it has been associated with several common issues that can affect its longevity and functionality.

Common Transmission Problems

1. Flashing Overdrive Light

A frequent issue with the 2002 Explorer's transmission is the flashing overdrive light, indicating a potential solenoid failure. This can lead to the transmission locking up, necessitating a rebuild after solenoid replacement.

2. Transmission Overheating

Overheating is another prevalent problem, which may occur even under normal operating conditions. Installing an aftermarket transmission cooler can help mitigate this issue, although it highlights a design flaw in the original system.

3. Harsh Gear Shifting

Owners often report harsh gear shifting, characterized by shuddering or vibrations during acceleration or downshifting. This may be due to a broken intermediate band, which can trigger diagnostic trouble codes like P0733.

4. Solenoid Failure

Solenoids control various functions within the transmission. Failure of these components can result in loss of gear shifting capabilities and torque converter malfunctions, often occurring after only a few thousand miles of use.
