CD009 6Spd Manual Transmission

CD009 6 Speed Manual Transmission for Sale. Low Mileage Nissan 350Z 6-Speed Gearbox.

The CD009 6 speed manual transmission is one of the most popular manual gearboxes in the performance and drift community. If you own a Nissan 350Z or Infiniti G35 and need a replacement transmission after an internal failure, a broken gear, or a mechanical issue that makes replacement more practical than repair, a clean low mileage Nissan CD009 transmission from a verified donor car is the direct path back to factory spec. At McClain Auto Part, we have been sourcing and selling used performance transmissions out of Cleveland, Ohio since 2009. The CD009 6-speed gearbox is one of the most consistently requested manual units we carry.

350Z and G35 owners come to us for a few reasons. Some deal with a broken 2nd gear synchro, a worn shift fork, or an internal failure on a high mileage original transmission. Others are rebuilding a 350Z or G35 that has good engine and body condition but a worn or damaged gearbox. In addition, a large and growing group of builders sources the 350Z CD009 transmission specifically as a CD009 manual swap transmission for LS swaps, SR20 builds, RB engine swaps, and other high output projects where the CD009 is the preferred gearbox for its torque capacity and gear ratios.

Whatever the situation, the goal is the same. A tested, documented Nissan 6 speed manual transmission that installs correctly and shifts the way it is supposed to.

The CD009 Transmission Platform

The CD009 is a 6-speed manual transmission Nissan used in the 350Z and Infiniti G35 coupe from 2003 onward. It replaced the earlier CD008 5-speed in the 350Z lineup and brought a sixth gear, revised gear ratios, and a higher torque capacity to the platform. As a result, it became one of the most sought-after factory manual gearboxes for both replacement and swap applications in the performance community.

Why the CD009 Became a Swap Standard

The CD009 manual swap transmission has a reputation that extends well beyond the 350Z and G35 community. Builders running LS engines, RB26 swaps, SR20 builds, and other high output engine combinations frequently choose the CD009 over other factory manual gearboxes because of its torque capacity, input shaft diameter, and readily available aftermarket support. Specifically, the CD009 handles significantly more torque than its factory rating suggests, which makes it a practical choice for high output builds where a fragile factory gearbox would be a liability.

CD009 Versus CD008

The CD008 is the earlier 5-speed manual used in the 350Z before the CD009 became standard equipment. The CD008 is a narrower gearbox with lower torque capacity and five forward gears. The CD009 added a sixth gear, improved shift feel in most configurations, and a stronger gear set. For replacement purposes, confirm which unit your car uses before ordering. For swap applications, the CD009 is the more capable choice in virtually every high output build scenario.

Gear Ratios and Final Drive

The CD009 gear ratios favor a balance between strong acceleration in the lower gears and a usable overdrive ratio in 6th for highway and circuit driving. The close ratio spacing in 2nd through 4th makes it a natural fit for performance driving applications where keeping the engine in its power band between corners matters. For street use, the 6th gear overdrive drops RPM at highway speed to a comfortable cruising range for the VQ35 and most common swap engines.

What Is Included

Included components vary by unit. Here is what a typical CD009 6-speed gearbox package from McClain includes.

Standard With Most Units

• Complete CD009 transmission assembly
• Shifter base and shift rod, condition noted
• Transmission mount bracket, condition documented
• Input shaft bearing retainer
• Gear oil fill, confirmed before shipping

Available on Select Units or by Request

• Flywheel, confirm compatibility with your engine application
• Clutch assembly, confirm application before ordering
• Driveshaft, confirm availability at time of order

A Note on Clutch and Flywheel

The CD009 ships without a clutch and flywheel unless confirmed at time of order. For a direct factory replacement in a 350Z or G35, your existing clutch and flywheel are typically reused if condition allows. For a swap application, confirm input shaft spline compatibility and clutch disc diameter for your specific engine before ordering. We advise on this when you call.

Condition and Inspection

Every Nissan CD009 transmission for sale that ships from our Cleveland warehouse goes through a hands-on inspection. The synchro condition and shift fork wear on the CD009 require specific attention during inspection, particularly on higher mileage units.

What We Check Before Every Unit Ships

• Full visual inspection of transmission case for cracks, leaks, and external damage
• Input shaft inspected for wear, spline condition, and bearing surface integrity
• Output shaft inspected for wear and flange condition
• Gear oil drained and inspected for metal particles or contamination
• Shift forks inspected for wear and bend condition where accessible
• Synchro condition noted based on oil condition and available inspection points
• Shifter base and shift rod inspected for wear and damage
• Mounting surfaces and transmission mount bracket inspected
• No grinding, popping out of gear, or unusual noise confirmed before packaging

Synchro condition and gear oil condition are documented on every unit before it ships. You know what you are getting before the order is processed.

Vehicle Compatibility

The CD009 6 speed manual transmission was factory-fitted in the following vehicles:

• Nissan 350Z, 2003 to 2008
• Infiniti G35 Coupe, 2003 to 2007

Before ordering for a direct factory replacement, confirm your VIN and build date. Minor updates occurred across model years that affect certain external components. For most factory replacement applications, these differences are minor and do not affect core function.

Common Swap Applications

The CD009 manual swap transmission is one of the most widely used factory gearboxes in the performance swap community. Common applications include:

• LS engine swaps into 240SX, S13, and S14 chassis
• RB26 and RB25 builds requiring a higher torque capacity gearbox
• SR20DET builds in S-chassis with upgraded power output
• 2JZ swap projects requiring a proven manual option
• Custom tube chassis and track car builds
• Any rear-wheel drive performance build where a strong factory 6-speed is preferred over a purpose-built racing gearbox

For swap applications, confirm bellhousing adapter compatibility for your engine, input shaft spline count, and driveshaft output flange dimensions before ordering. Call us with your application and we give you practical guidance on what the swap requires.

Swap and Installation Notes

Bellhousing Adapters

The CD009 uses a Nissan-specific bellhousing bolt pattern. For swap applications with non-Nissan engines, a bellhousing adapter is required. Adapters are available from multiple suppliers for the most common swap combinations including LS, RB, SR20, and 2JZ applications. Confirm adapter availability and input shaft length compatibility for your specific engine before ordering the transmission.

Input Shaft and Clutch

The CD009 uses a 32mm input shaft spline. Confirm your clutch disc matches this spline count for your specific application. For swap builds, most aftermarket clutch suppliers offer CD009-compatible discs in various clutch diameter and clamp load options matched to different engine output levels.

Driveshaft

The CD009 output flange uses a standard Nissan bolt pattern. For factory 350Z and G35 replacements, the original driveshaft connects directly. For swap applications, a custom driveshaft is typically required. Measure the transmission output flange to differential input distance in your chassis before ordering a custom shaft.

Gear Oil

Fill the CD009 with Nissan MT fluid or a quality GL-4 gear oil on installation. Do not use GL-5 gear oil in the CD009. GL-5 chemistry is corrosive to the yellow metal components in the CD009 synchro system and causes premature synchro wear. This is a straightforward step that significantly affects transmission longevity.

Break-In

New or replacement manual transmissions benefit from a break-in period of several hundred miles at moderate loads before sustained hard use. Shift through all six gears during break-in and avoid sustained high RPM drops into lower gears until the synchros have had time to seat. Change the gear oil after the first 500 miles on a fresh unit.
