CD009 Transmission
The CD009 transmission was the original manual gearbox offered in the Infiniti G35. It was a six-speed unit that was known for its smooth shifting and precise gear engagement. The CD009 was a robust and reliable transmission, but it was also prone to some issues. One of the most common complaints was that the CD009 could be prone to wear and tear, especially in high-performance applications. This was due to the fact that the CD009 was a relatively early design and did not have the same level of durability as the later CD00A transmission.
The CD009 transmission was used in the G35 sedan and coupe from 2003 to 2006. In 2007, the G35 coupe received the updated CD00A transmission, but the CD009 remained available in the G35 sedan. The CD009 transmission was a popular choice among G35 owners, but it was important to be aware of its potential weaknesses.
With proper maintenance and care, the CD009 transmission could provide many years of reliable service; However, if you were planning to use your G35 for high-performance driving, it was important to consider upgrading to the CD00A transmission.
CD00A Transmission
The CD00A transmission was introduced in 2007 as a successor to the CD009, aiming to address the shortcomings of its predecessor.

Common Issues and Solutions
While the Infiniti G35’s manual transmission is known for its robustness, like any mechanical component, it’s not immune to issues. One common problem is a “soft” or “mushy” shifter, which can be attributed to worn shifter bushings or a loose linkage. Replacing the bushings and adjusting the linkage can restore a crisp and precise shifting feel. Another issue that can arise is a grinding noise during gear changes, particularly when shifting into first or reverse. This often indicates worn synchronizers, which can be replaced to eliminate the noise.
Additionally, leaks from the transmission itself can occur, usually from the seals or gaskets. Addressing leaks promptly is crucial to prevent further damage and potential contamination of the transmission fluid. In some cases, the transmission may also exhibit difficulty shifting into specific gears or experience a complete loss of power. These issues can stem from a variety of causes, including a faulty clutch, damaged gears, or a malfunctioning hydraulic system. Diagnosing the specific cause is crucial to selecting the appropriate repair.
Furthermore, the G35’s manual transmission is susceptible to issues related to the clutch. Clutch slippage, which manifests as a loss of power during acceleration, can be caused by a worn clutch disc or a hydraulic system malfunction. A clutch replacement may be necessary to rectify this problem. In some instances, clutch judder, a vibration felt during engagement, can occur due to worn clutch components or improper installation.
Maintenance and Repair
Proper maintenance is crucial to ensuring the longevity and optimal performance of your G35’s manual transmission. Regular fluid changes are essential, as the transmission fluid degrades over time and can lead to wear and tear on internal components.
