1. Parts and Components:
* Turbo 350 Transmission: This is the obvious first step. Ensure it's in good working order, or have it rebuilt beforehand.
* Transmission Mount: You'll need a mount specifically designed for a Turbo 350 in a '56 Chevy. These are not interchangeable across years and models.
* Driveshaft: The original driveshaft will almost certainly be incompatible. You'll need a custom driveshaft made to the correct length for your specific application, taking into account the Turbo 350's output shaft length and your rear axle.
* Crossmember: You'll need a crossmember to support the transmission. Again, a '56 Chevy-specific crossmember for a Turbo 350 is essential. This may require modification or fabrication.
* Shifter: A shifter linkage compatible with the Turbo 350 and your chosen shifter location (floor or column). This will likely require adaptation.
* Torque Converter: The torque converter must match the transmission.
* Fluid and Filter: Appropriate transmission fluid and a new filter.
* Flexplate/Flywheel: A flexplate (for an automatic transmission) that fits both the crankshaft and the torque converter.
* Bellhousing: You'll need a bellhousing that correctly mates the Turbo 350 to your engine. Again, this will be specific to your engine type (e.g., small block Chevy, big block Chevy).
2. Tools and Equipment:
* Transmission Jack: Essential for safely handling and installing the transmission.
* Engine Hoist (potentially): May be needed to remove and reinstall the engine if you're not doing this alongside an engine overhaul.
* Socket Set and Wrenches: A complete set of metric and SAE sockets and wrenches, including deep sockets and extensions.
* Torque Wrench: Absolutely critical for proper tightening of bolts to prevent leaks and damage.
* Pry Bar and Hammer (used carefully): For prying and tapping parts into place, when appropriate.
* Mechanic's Gloves: Protecting your hands is crucial.
* Shop Manual (specific to your 1956 Chevy): This will provide detailed diagrams and instructions for your vehicle. A good transmission manual for the Turbo 350 would also be invaluable.
3. Installation Process (Simplified Overview):
1. Vehicle Preparation: Disconnect the battery, drain fluids (transmission, coolant etc.), and remove the old transmission.
2. Install Crossmember and Mount: Secure the new crossmember and transmission mount.
3. Install Torque Converter: This step requires careful alignment.
4. Install Transmission: Carefully lower the Turbo 350 into place using a transmission jack, aligning it with the engine and bellhousing.
5. Connect Shifter Linkage: Assemble and adjust the shifter linkage.
6. Install Driveshaft: Connect the new driveshaft.
7. Fill with Fluid: Add the correct amount and type of transmission fluid.
8. Test and Adjust: Start the engine, check for leaks, and test the shifting operation.
Important Considerations:
* Engine Compatibility: Ensure the Turbo 350 is compatible with your engine (e.g., small block Chevy, big block Chevy). The bellhousing is critical here.
* Professional Help: If you lack experience, consider seeking professional help. Improper installation can lead to significant damage.
* Safety: Work in a well-ventilated area and follow all safety precautions.
This is a vastly simplified overview. The actual installation process is complex and involves numerous detailed steps. Consulting a repair manual specific to your 1956 Chevy and the Turbo 350 transmission is absolutely essential for a successful installation. A shop manual for your vehicle and a reputable Turbo 350 transmission guide are your best resources.
