General Steps (Simplified and NOT a complete guide):
1. Safety First: Disconnect the negative battery cable. Support the vehicle securely on jack stands. Wear safety glasses and gloves.
2. Fluid Drainage: Drain the transmission fluid completely.
3. Component Removal: This involves disconnecting numerous components:
* Driveshaft: Disconnect the driveshaft from the transmission.
* Shift Linkage: Disconnect the shift linkage from the transmission.
* Cooling Lines: Disconnect the transmission cooler lines (carefully, as fluid will spill).
* Electrical Connectors: Disconnect all electrical connectors from the transmission.
* Exhaust System (potentially): Parts of the exhaust system might need to be loosened or removed for access.
* Torque Converter: This will need to be separated from the transmission. This often requires a special tool.
* Transmission Mount(s): Remove the transmission mount(s) securing the transmission to the vehicle.
4. Transmission Removal: Carefully lower the transmission using a transmission jack. This requires careful maneuvering and precision to avoid damage.
5. Installation of New Transmission: This process is essentially the reverse of removal. Make sure to use a new transmission gasket and filter. Torque bolts to the manufacturer's specifications.
6. Refill and Bleeding: Refill the transmission with the correct type and amount of fluid. Bleeding the transmission lines might be necessary to remove air bubbles.
7. Reconnect Components: Carefully reconnect all components removed in step 3, ensuring everything is securely fastened.
8. Testing: Start the engine and check for leaks. Test drive the vehicle carefully, checking for proper shifting and operation.
Tools and Equipment Needed (Partial List):
* Transmission Jack: Absolutely essential.
* Jack Stands: For safety.
* Torque Wrench: Crucial for proper tightening.
* Socket Set: A wide range of sockets and extensions.
* Wrenches: Various sizes.
* Pry Bars: Possibly needed for stubborn components.
* Shop Manual: A detailed repair manual specific to your 2000 Ford Windstar is indispensable.
* New Transmission Gasket and Filter: Essential for a proper seal.
* Transmission Fluid: The correct type and amount for your transmission.
* Possibly a Torque Converter Wrench: To remove and install the torque converter.
Why You Should Consider a Professional:
* Complexity: The process is incredibly complex and involves many intricate steps.
* Specialized Tools: You'll need specific tools, some of which are expensive.
* Potential for Damage: Incorrect installation can lead to serious and costly damage.
* Safety: Working under a vehicle can be dangerous.
In short: Unless you have extensive automotive experience, access to a well-equipped shop, and a detailed repair manual, it's strongly recommended that you take your Windstar to a qualified mechanic for transmission replacement. The cost of professional repair is far less than the potential cost of damaging your vehicle or injuring yourself during a botched DIY attempt.
