Transmission Codes: JK41/CD009/CD00A
The 6-speed manual transmissions found in Nissan 350z/370z and Infiniti G35/G37 Coupe and Sedan models offer robust performance comparable to a T56 but at a more affordable price.
- Available at a budget-friendly cost when purchased used (recommended post-2006 models).
- Priced at around 2300 USD when purchased brand new.
The latest OEM 6MT Manual Transmission, known by the code JK41x, eliminates issues with soft synchronizers and grinding shifts from earlier models. It shares the same durable components as the CD009/CD00A, featuring triple cone synchros for 1st, 2nd, and 3rd gears and double cone synchros for 4th gear. This design represents a significant improvement over its predecessors, such as CD008, CD005, CD003, and CD000, known for early synchro failures.
Why Opt for a CD009?
Enthusiasts choose the CD009 transmission for a variety of reasons, including:
- Widely available
- Cost-effective
- Smooth shifting
- Proven reliability
- Capable of handling high power
- Extensive aftermarket parts support
Power Holding Capacity
The CD009 is favored in the swapping community for consistently managing high horsepower. Unofficially, it has demonstrated strength in excess of what is typically required for an average motor swap, with tested reliability in vehicles producing over 1000 whp.
Gearing Considerations
Gearing significantly influences vehicle performance. Longer gear ratios, as seen in the CD009, result in slower acceleration but less shifting time and higher top-end speeds. In comparison to the T-56, the CD009 provides longer gears, making it a better choice for acceleration and overall performance on and off the track.
