However, if you're determined to attempt this yourself, here's a general outline of the steps involved. Remember, this is a simplified overview, and you'll need a detailed repair manual specific to your year and model Windstar for precise instructions and torque specifications. A Haynes or Chilton manual is a good investment.
1. Preparation:
* Safety First: Disconnect the negative battery cable. Use jack stands to securely support the vehicle after lifting it. Wear safety glasses and gloves.
* Gather Tools: You'll need a variety of tools, including wrenches (metric), sockets, ratchets, a transmission jack, a torque wrench, pry bars, a drain pan, and possibly a fluid pump.
* Fluid Drainage: Drain the transmission fluid completely. Allow time for it to drain fully.
2. Component Removal:
* Exhaust System: You'll likely need to loosen or remove parts of the exhaust system to gain access to the transmission.
* Driveshaft(s): Disconnect the driveshaft(s) from the transmission. This usually involves unbolting the driveshaft from the transmission flange and potentially removing the center support bearing.
* Shift Linkage: Disconnect the shift linkage from the transmission.
* Electrical Connectors: Disconnect all electrical connectors from the transmission. Take pictures to aid in reassembly.
* Cooling Lines: Disconnect any transmission cooler lines, carefully catching any remaining fluid.
* Torque Converter: This may require a special tool to separate the torque converter from the transmission.
* Transmission Mount(s): Remove the transmission mount(s) that secure the transmission to the vehicle's frame.
* Starter: May need to be removed for better access.
3. Transmission Removal:
* Transmission Jack: Carefully use a transmission jack to support the weight of the transmission.
* Bolts: Remove the bolts securing the transmission to the engine.
* Lowering the Transmission: Slowly and carefully lower the transmission using the transmission jack. Be mindful of clearance issues.
4. Reassembly (Reverse of Removal): This process is the reverse of removal, but precise torque specifications are crucial to prevent future problems. Refer to your repair manual for detailed instructions.
Important Considerations:
* Torque Specifications: Following the correct torque specifications is essential to prevent damage. Use a torque wrench.
* Fluid: Use the correct type and amount of transmission fluid as specified in your owner's manual.
* Alignment: Proper alignment of the transmission during reinstallation is crucial.
* Professional Assistance: If you're uncomfortable with any step, stop and seek professional help.
This is a simplified overview. Attempting this without a detailed repair manual and significant mechanical experience is highly discouraged. The potential for damage and injury is substantial. Please consult a professional mechanic for this repair.
