Adapter Plates and Customization Needs
Adapter plates are essential for mating manual transmissions to LS engines, ensuring proper alignment and functionality. Companies like FABbot, Collins, and LOJ Conversions offer kits for popular transmissions such as the T56, TR6060, and CD009. These plates often require modifications, such as cutting the factory bell housing, especially for the CD009. Custom flywheels and clutch systems are frequently needed, with options varying by transmission type. For instance, the CD009 typically uses a 6-puck clutch, which can be less desirable for some drivers. Budget plays a significant role, as adapter plates and associated parts can range from a few hundred to several thousand dollars. Enthusiasts must also consider factors like transmission input shaft spline compatibility and shifter placement. Proper customization ensures a seamless integration, allowing the LS engine to perform optimally with the chosen manual transmission.
Budget Considerations
Budget is a critical factor when selecting a manual transmission for an LS swap. Options like the NV3500 and AR5 offer affordability, with the NV3500 often found in junkyards for a few hundred dollars. The T56 and CD009, while popular, have seen price increases due to demand, with used CD009s now costing around $1,000. Adapter plates and additional components, such as the FABbot adapter kit for the CD009, can add $400 to $2,000, depending on the setup. Custom flywheels and clutch systems further inflate costs, especially for transmissions like the CD009, which often require a 6-puck clutch. For those on a tighter budget, considering a used transmission and inspecting its condition can help save money. However, rebuilds or upgrades may still be necessary. Balancing performance needs with financial constraints is essential to ensure the project remains viable without compromising reliability or drivability.
Driving Experience and Future Plans
The choice of manual transmission significantly impacts the driving experience in an LS swap. Transmissions like the T56, known for reliability, may lack the refined shifting feel of newer options like the TR6060 or CD009. Future plans often involve upgrading to stronger units like the TR6060 or BMW ZF/Getrag transmissions for higher power applications. Many enthusiasts prioritize transmissions with smoother shifting and better gear ratios to enhance drivability; For those planning to increase power, selecting a transmission with higher torque capacity is essential. Additionally, considerations like clutch choice and shifter placement play a role in the overall driving experience. Future modifications may include aftermarket components to improve shifting characteristics or adaptability for specific driving styles, ensuring the transmission aligns with long-term performance goals.
