The process involves:
1. Disconnecting the driveshaft: This is crucial before removing the transmission. You'll need to support the driveshaft properly.
2. Removing the transmission cooler lines: Carefully disconnect these lines and plug them to prevent fluid loss.
3. Disconnecting the shift linkage: This varies slightly depending on the specific transmission, but generally involves disconnecting the linkage rods or cables.
4. Disconnecting the electrical connectors: Several electrical connectors connect to the transmission; disconnect these carefully.
5. Removing the crossmember: The transmission crossmember must be removed to allow access to the transmission bolts.
6. Removing the torque converter: This typically involves using a torque converter wrench.
7. Unbolting the transmission: Now you can access the top bolts along with all the others. These are likely located on the bell housing where the transmission mates with the engine.
Important Considerations:
* Safety: This is a significant job requiring mechanical aptitude and the right tools. Safety precautions are essential – jack stands, safety glasses, gloves, etc.
* Transmission Jack: You will absolutely need a transmission jack to support the weight of the transmission as you remove and reinstall it. Trying to do this without one is extremely dangerous and can lead to injury.
* Fluid: Expect significant transmission fluid loss. Have a drain pan ready and plan to refill with the correct fluid type and amount after reinstallation.
* Torque Specifications: Use a torque wrench and refer to a repair manual for the proper torque specifications for all bolts.
Before attempting this, consult a repair manual specific to your 1998 S-10 Blazer. This will provide detailed instructions, diagrams, and torque specifications. If you're not comfortable performing this repair yourself, it's best to take it to a qualified mechanic. Improper removal or reinstallation can damage the transmission or other components.
