However, I can give you a general overview of the process. This is not a comprehensive guide, and you should consult a repair manual specific to your 1992 Cadillac Seville (including the engine type – the transmission removal procedure varies slightly depending on the engine). A Haynes or Chilton manual is a good place to start.
General Steps (Highly Simplified):
1. Disconnect the Battery: This is crucial to prevent electrical shorts.
2. Drain Fluids: Drain the transmission fluid completely. You'll also likely need to drain the coolant if the transmission cooler is integrated into the radiator.
3. Disconnect Components: Disconnect various components connected to the transmission, including:
* Driveshafts: Disconnect both the input and output shafts.
* Shift linkage: Disconnect the shift linkage from the transmission.
* Electrical connectors: Disconnect all electrical connectors, such as the speed sensor and reverse light switch.
* Cooling lines: Disconnect transmission cooler lines (if applicable).
* Torque converter: This might require a special tool to separate the torque converter from the flexplate.
* Exhaust system: May need partial removal to provide clearance.
4. Support the Transmission: Use a transmission jack to securely support the transmission's weight. This is vital to prevent damage and injury.
5. Remove the Transmission Mount(s): Remove the bolts holding the transmission mount(s) to the vehicle's chassis and transmission.
6. Separate the Transmission: Carefully lower the transmission using the jack. This often requires maneuvering the transmission around engine components and other parts of the vehicle. There may be tight clearances, requiring patience and precise movements.
7. Remove the Transmission: Once clear, carefully remove the transmission from the vehicle.
Tools You Will Likely Need:
* Transmission jack: Absolutely essential.
* Socket set: Various sizes.
* Wrenches: Various sizes.
* Torque wrench: To tighten bolts to the correct specifications.
* Pry bars: Might be needed to break loose stubborn connections.
* Floor jack and jack stands: For supporting the vehicle.
* Drain pan: For catching fluids.
* Repair manual: Absolutely essential.
Safety Precautions:
* Work in a well-ventilated area: Transmission fluid fumes can be harmful.
* Wear safety glasses: Protect your eyes from debris.
* Wear gloves: Protect your hands from grease and fluids.
* Use jack stands: Never work under a vehicle supported only by a jack.
Reinstallation is the reverse of removal, but equally challenging. Again, this is a very difficult job requiring expertise. If you're not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. The cost of professional repair is far less than the potential cost of damage caused by an improper attempt at DIY repair.
