What is the CD009 Transmission?
The CD009 transmission is a part of the FS6R31A family, first introduced in 2003 with the Nissan 350Z. It features a 6-speed manual configuration which provides improved performance characteristics over its predecessor, the CD008. The addition of a sixth gear allows for more efficient power delivery, resulting in better acceleration and fuel efficiency. Its longitudinal layout supports rear-wheel-drive applications, ensuring compatibility with various high-performance engines.
Key Features and Benefits of the CD009
- Enhanced Torque Capacity: The CD009 is rated for approximately 280 lb-ft of torque but often handles much more in real-world applications, making it suitable for high-horsepower builds.
- Wide Gear Ratios: The close ratio between 2nd to 4th gears helps maintain optimal engine RPM during cornering sequences, enhancing performance in both racing and daily driving scenarios.
- Aftermarket Support: As a widely recognized transmission in the performance community, it has extensive aftermarket support, including adapter kits for popular engine swaps like LS, RB, and SR.
- Reliability: Many builders choose the CD009 over rebuilt alternatives due to its documented mileage and known performance history, offering peace of mind in high-stress applications.
Common Applications in Performance Vehicles
The CD009 is not limited to its original applications in the Nissan 350Z and Infiniti G35. It has become popular in various performance vehicle scenarios, including:
- LS engine swaps in Nissan 240SX (S13 and S14)
- RB26 and RB25 builds seeking higher torque capacity
- High-output SR20DET builds in S-chassis
- 2JZ engine swaps requiring a robust 6-speed option
- Custom builds and tube chassis applications
Recognizing CD009 Transmission Specifications
Technical Specifications and Gear Ratios
Understanding the technical specifications of the CD009 transmission is crucial for ensuring compatibility and performance in any potential application. Some key specifications include:
- Transmission Type: 6-speed manual
