Nissan CD009 Transmission Adapter Plate: A DIY Solution for VQ35DE Swaps

When it comes to swapping a VQ35DE engine into an L-Series block, one of the biggest challenges is finding a transmission that can handle the power and torque output. The Nissan CD009 transmission is a popular choice among enthusiasts due to its robust syncros and ability to handle high-performance applications. However, installing this transmission requires a custom adapter plate to mate it to the L-Series engine.

The key to this project was designing an adapter plate that requires little to no machining and can be done in the home garage. To achieve this, we used accurate bolt and alignment feature measurements along with perimeter profiles provided by the CD009 transmission and L-Series engine block. The profiles were transferred by hand and scanned into a computer for digitization.

One of the unique challenges when adapting the CD009 transmission to an L-Series engine is the difference in bellhousing height between the two platforms. The 350z's dual mass flywheel and clutch assembly is much taller than the L-Series, which places the input shaft splines further away from the engine. This required a custom design for the adapter plate to properly align the L-Series clutch with the CD009 transmission input shaft and clutch hydraulics.

The end result of this project is an adapter plate that allows enthusiasts to install a CD009 transmission on their L-Series engine without having to machine the bellhousing or perform extensive modifications. This solution makes it more accessible for DIYers to upgrade their vehicles with a high-performance transmission.

For turbocharged applications, a 3.36 or 3.54 gear ratio may be preferred to help load the engine down low. The CD009 transmission is a close-ratio transmission, which provides a short first gear and excellent low-end acceleration when matched with a short rear axle ratio.

The later revisions of the CD009 transmission, such as the CD009, have robust syncros and are capable of handling high levels of power and torque output. This makes it an ideal choice for L-Series builds that require a strong and reliable transmission.

In conclusion, the Nissan CD009 transmission adapter plate is a game-changer for enthusiasts looking to upgrade their vehicles with a high-performance transmission. With its custom design and ability to be installed in the home garage, this solution provides a cost-effective way to install a powerful and reliable transmission on an L-Series engine.
