1. Preparation is Key:
* Safety First: Disconnect the negative battery cable. Support the vehicle securely on jack stands. Never work under a vehicle supported only by a jack.
* Gather Tools: You'll need a variety of sockets, wrenches, screwdrivers, a transmission jack, torque wrench, and possibly a transmission fluid pump to drain the transmission. A shop manual will list the exact tools and torque specifications.
* Drain Transmission Fluid: Completely drain the transmission fluid into a suitable container. This is crucial to prevent a mess. Consider using a transmission fluid pump to remove as much fluid as possible.
* Disconnect Components: Disconnect the various linkages, electrical connectors, cooling lines, and driveshaft from the transmission. This varies depending on your specific vehicle, so your repair manual will be invaluable here. Take pictures as you go to aid in reassembly.
2. Transmission Removal:
* Support the Transmission: Use a transmission jack to support the transmission's weight as you remove the bolts connecting it to the engine. This is extremely important to prevent damage.
* Remove Transmission Bolts: Carefully remove the bolts attaching the transmission to the engine. They are typically located around the bellhousing.
* Lower the Transmission: Slowly lower the transmission using the transmission jack. Be mindful of clearance issues as you maneuver it out from under the vehicle.
3. Accessing the Torque Converter Bolts:
* Once the transmission is removed, you'll have clear access to the torque converter bolts that attach it to the flexplate (which is bolted to the flywheel). These bolts are usually recessed, requiring a socket of appropriate size and length.
* Remove the Torque Converter: You may need to use a torque converter wrench or a special tool to remove the converter.
4. Reassembly:
* Reassembly is the reverse of disassembly. Remember to carefully install the torque converter and transmission, making sure the transmission fluid is properly filled to the correct level. This usually involves running the engine to let the transmission pump prime itself. Consult the repair manual for precise instructions.
Important Notes:
* Repair Manual: This is crucial. A generic description isn't sufficient for this complex task. A factory service manual will provide detailed diagrams, torque specifications, and procedures specific to your 1998 Chevy S-10.
* Transmission Jack: Absolutely essential to prevent damage to the transmission.
* Transmission Fluid: Use the correct type and amount of transmission fluid recommended by your vehicle's manufacturer.
* Professional Help: If you're not comfortable performing this type of repair, consider taking it to a qualified mechanic. Improperly reinstalling the transmission can lead to costly damage.
This is a complex repair. If you're not experienced with automotive repair, seeking professional help is highly recommended. The cost of repairing damage from an improperly performed job will likely outweigh the cost of having a mechanic do it correctly.
