However, if you're determined to do it yourself, here's a general overview of the process. This is a simplified summary and doesn't cover every detail. Consult a detailed repair manual specific to your 1979 Corvette for complete and accurate instructions. A factory service manual or a reputable aftermarket manual like a Chilton's or Haynes is crucial.
Tools and Equipment You'll Need:
* Transmission Jack: Absolutely essential to support the transmission's weight.
* Engine Hoist (optional but highly recommended): May make engine/transmission removal easier.
* Torque Wrench: Critical for tightening bolts to the correct specifications.
* Sockets and Wrenches (various sizes): Metric and SAE may be needed.
* Ratchets and Extensions: For reaching hard-to-access bolts.
* Pry Bars (plastic or wood preferred to avoid damage): For separating components.
* Drain Pan: To catch transmission fluid.
* Shop Rags: Lots of them!
* New Transmission Filter and Gasket: Always replace these during a transmission removal.
* New Transmission Fluid: Use the correct type and amount specified in your manual.
* Possibly a new torque converter: This may be damaged during removal or may be wise to replace.
* Safety Glasses and Gloves: Essential for protection.
* Repair Manual: Your Bible for this project.
Removal Process (General Steps):
1. Disconnect the Battery: This is crucial to prevent accidental shorts.
2. Drain the Transmission Fluid: Allow ample time for it to drain completely.
3. Disconnect the Driveshaft: This usually involves removing the driveshaft yoke from the transmission tailhousing.
4. Disconnect the Shift Linkage: Carefully detach the linkage connecting the transmission to the shifter.
5. Disconnect the Electrical Connections: Unplug any electrical connectors from the transmission.
6. Disconnect the Cooler Lines: Carefully disconnect the transmission cooler lines, being prepared for fluid spillage.
7. Disconnect the Torque Converter: This step will require separating the transmission from the engine's flex plate.
8. Support the Transmission: Securely attach the transmission jack to the transmission.
9. Remove the Transmission Mount Bolts: Carefully remove the bolts securing the transmission to the vehicle's frame.
10. Remove the Transmission: Slowly and carefully lower the transmission using the transmission jack.
Installation Process (General Steps):
1. Prepare the New Transmission: Install a new filter and gasket.
2. Position the Transmission: Carefully guide the new transmission into place, using the transmission jack.
3. Connect the Torque Converter: Securely attach the converter.
4. Reconnect the Mount Bolts: Tighten the bolts to the manufacturer's specifications.
5. Reconnect Everything Else: Reconnect all the components you disconnected during removal (driveshaft, shift linkage, cooler lines, electrical connectors).
6. Fill with Transmission Fluid: Add the correct amount and type of transmission fluid.
7. Check Fluid Level: Use the dipstick to verify the fluid level is correct.
8. Start the Engine and Check for Leaks: Run the engine for a short period to check for leaks.
9. Test Drive: Take a short test drive to verify proper shifting and functionality.
Important Considerations:
* Alignment: Precise alignment of the transmission to the engine is crucial.
* Torque Specifications: Use a torque wrench and follow the specifications in your repair manual meticulously.
* Safety: This is heavy work. Use proper lifting techniques and safety equipment.
This is a highly simplified overview. You absolutely MUST consult a detailed repair manual specific to your 1979 Corvette for the correct procedures and torque specifications. Improper installation can lead to serious damage to your vehicle. Again, if you are not comfortable with this level of automotive repair, please take your vehicle to a professional.
