Here's a breakdown of how to approach the problem:
1. Diagnosis is Crucial:
* Identify the Problem: What are the symptoms? Is it slipping, shifting hard, making noise, refusing to shift, or completely inoperative? Be specific. The more detail you provide a mechanic, the better they can diagnose the issue.
* Check the Fluids: Start with the easiest and cheapest check. Check the transmission fluid level and condition. Low fluid, burnt fluid (smells burnt, dark brown/black), or milky fluid (indicates water contamination) are all serious signs.
* Professional Diagnosis: Unless you have extensive transmission repair experience, take your Explorer to a reputable transmission shop or mechanic specializing in Ford vehicles. They have the tools and expertise to diagnose the problem accurately, often using diagnostic scanners to read transmission codes.
2. Possible Repairs (Depending on the Diagnosis):
* Fluid and Filter Change: This is the least invasive and cheapest option. It's preventative maintenance and might resolve minor issues like rough shifting. However, it won't fix major internal damage.
* Solenoid Replacement: Solenoids control the shifting process. A faulty solenoid can cause various shifting problems. Replacing them is often less expensive than a complete rebuild.
* Torque Converter Replacement: The torque converter is a critical component that transfers power from the engine to the transmission. Failure can cause slipping or lack of power.
* Transmission Rebuild: This involves disassembling the transmission, replacing worn parts (seals, clutches, bands, etc.), and reassembling it. It's expensive but often necessary for major internal damage.
* Transmission Replacement: In some cases, a complete transmission replacement might be the most cost-effective solution, especially if the damage is extensive or the transmission is nearing the end of its life. Consider a used, rebuilt, or new transmission.
3. Costs:
Expect to pay anywhere from a few hundred dollars (fluid change) to several thousand dollars (rebuild or replacement). Rebuilt transmissions are generally less expensive than new ones.
4. DIY Considerations:
* Difficulty: Transmission repair is extremely complex. Unless you have significant mechanical experience and specialized tools (transmission jack, etc.), attempting a DIY repair is strongly discouraged. You risk causing further damage and potentially injuring yourself.
* Warranty: If you attempt a DIY repair and fail, you'll void any warranty on replacement parts.
In summary: Don't try to fix a 2002 Ford Explorer transmission yourself unless you're a highly skilled mechanic. Get a professional diagnosis first. The cost of a proper diagnosis is far less than the potential cost of misdiagnosing and improperly repairing the transmission yourself. Remember to clearly describe the symptoms to your mechanic for accurate diagnosis and repair.
