Pros and Cons of Buying a GM 8624912 Turbo Trans TH350 No Governor Gear Kit for 1966-1968 Chevrolet Trucks

Pros:

4. Cost-Effective: Compared to other transmission upgrade options, such as a rebuilt transmission or a new one, a governor gear kit is a cost-effective solution.

Cons:

1. Complex Installation: Installing a turbocharger and a TH350 transmission with a no governor gear kit requires a significant amount of technical knowledge and experience. It may be necessary to hire a professional to ensure the installation is done correctly.

2. Potential Compatibility Issues: Before purchasing the kit, ensure that it is compatible with your specific engine and transmission configuration. Incorrect installation can lead to transmission damage and other issues.

3. Additional Maintenance: A turbocharged engine and a modified transmission require more frequent maintenance than a stock setup. Regular checks and servicing are necessary to ensure proper function and longevity.

4. Risk of Damage: Increased power output from the turbocharger and the modified transmission can result in higher stress on various components, including the engine, transmission, and drivetrain. Proper installation and maintenance are crucial to avoid damage.

Conclusion:

The GM 8624912 Turbo Trans TH350 No Governor Gear Kit offers several advantages, such as improved performance, customizability, and availability. However, it also comes with potential drawbacks, including complex installation, compatibility issues, additional maintenance, and the risk of damage.

Before purchasing the kit, carefully weigh the pros and cons and consider your technical expertise, budget, and desired performance level. If you are confident in your abilities and willing to invest time and resources into the installation and maintenance, a TH350 transmission with a no governor gear kit can be an excellent upgrade for your 1966-1968 Chevrolet truck.

Recommendation:

If you are unsure about the installation process or have limited experience with performance modifications, it may be wise to consider alternative options, such as a rebuilt transmission or a transmission cooler, that offer similar performance benefits but with fewer complications.
