1. Preparation is Key:
* Safety First: Disconnect the battery negative terminal. Support the transmission with a jack and jack stands. Never work under a vehicle supported only by a jack.
* Consult a Repair Manual: A factory service manual or a reputable repair manual specific to your S-10's year and model is crucial. It will show you exactly where the bolts are, their size, and the proper torque specifications for reinstallation.
* Tools You'll Need: Sockets (likely metric), wrenches (possibly combination or ratcheting), extensions, and a universal joint (to reach awkwardly angled bolts). A torque wrench is essential for proper reinstallation. Possibly a breaker bar for stubborn bolts. Penetrating oil (like PB Blaster) is highly recommended.
2. Accessing the Bolts:
* Locate the Bolts: The top transmission bolts are usually found on the bellhousing, the area where the transmission mates to the engine. They'll be fairly large bolts.
* Clear Obstructions: You might need to remove some components for better access. This could include things like the starter motor, parts of the exhaust system (heat shields especially), or even the air intake system, depending on your truck. Your repair manual will guide you.
* Apply Penetrating Oil: Generously spray penetrating oil on the bolts several hours (or even overnight) before attempting to remove them. This will help loosen them and prevent stripping.
3. Removing the Bolts:
* Start with the Easiest: Begin with the bolts that are most accessible. Use the appropriate socket and extension.
* Use the Right Technique: Avoid applying excessive force. If a bolt is resisting, try using a breaker bar or impact wrench (if you have one and know how to use it safely). If it's still stuck, you might need to carefully apply heat (with a propane torch, taking extreme care to avoid fire hazards). Never use excessive force on a bolt you suspect is stripped.
* Work Methodically: Remove one bolt at a time, keeping track of where each one came from. A numbered diagram or photo can be very helpful.
4. After Removal:
* Clean the Bolts: Clean any dirt or debris from the bolts and threads before storing them.
* Inspect the Bolts: Check the condition of the bolts. Replace any that are damaged or stripped.
* Clean the mating surfaces: Clean any gasket material, debris, and oil from the engine and transmission mating surfaces.
Important Notes:
* Transmission Support: Even with the top bolts removed, the transmission will still be largely supported by the rest of the bolts. However, carefully support the transmission with a jack throughout the process to prevent damage.
* Professional Help: If you're uncomfortable performing this task, it's always best to seek professional help from a qualified mechanic. Improperly removing these bolts can lead to significant damage to your vehicle.
This is a general outline. Your S-10's specific situation might require variations to this procedure. Always consult your repair manual and prioritize safety. Remember to replace the bolts with the correct ones and tighten them to the manufacturer’s specified torque.
