If you're shopping for a CD009 transmission, you've probably noticed most guides online either repeat the same three facts or bury the useful details under a wall of jargon. Some competitor pages cover fitment but skip pricing, while others focus on swap kits without explaining what actually breaks under load.

This article tries to cover all of it in one place. We'll cover what the CD009 actually is, which cars used it, how much power it can take, and what a full swap costs in 2026.

What Is the CD009 Transmission?

The CD009 is a six-speed manual gearbox built by Nissan. It's known for being tough, affordable, and easy to find in junkyards, which is why it shows up in so many engine swap builds.

Where the Name Comes From

Nissan used the CD prefix for a family of manual transmissions. The 009 refers to a later revision with stronger internals than the earlier CD models.

CD009 vs CD00A vs JK41A

These three often get mixed up. The CD00A is a close cousin used in some export markets, and the JK41A is a different casing found in older 350Z models before the CD009 became standard. If you're buying used, check the casing stamp before assuming compatibility.

How to Identify a CD009

Look for the casting number on the transmission housing near the bellhousing. There's usually a small metal tag riveted near the top of the case with a partial VIN or build code, which can help confirm the donor vehicle. Most CD009 units also have a distinct aluminum case shape that's slightly different from earlier Nissan manuals.

Which Cars Came With a CD009?

Nissan 350Z and 370Z

The 350Z used the CD009 starting around 2003, and it carried into the 370Z as well. Both cars paired it with the VQ35DE engine, which makes sense given how the transmission was tuned for that power band.

Infiniti G35 and G37

Infiniti's G35 and G37 shared the same platform as the 350Z and 370Z, so they got the same CD009 gearbox with minor tuning differences.

Year and Model Differences

Nissan updated the synchros partway through 2004, moving to a triple cone design on the early gears. This made shifting smoother and reduced grinding, so later units are generally the better find if you have a choice.

CD009 Gear Ratios and Final Drive

Gear ratios stay fairly consistent across CD009 units, though small variations exist by year:

Gear	Ratio
1st	3.79:1
2nd	2.32:1
3rd	1.62:1
4th	1.27:1
5th	1.00:1
6th	0.79:1
Final drive	3.54:1

These ratios lean toward quick acceleration rather than a high-top speed, which is part of why the CD009 works well for street and track builds.

How Much Power Can a CD009 Handle?

Stock Torque Limit

Most sources put the stock torque rating around 400 lb ft, though this can vary depending on driving style and maintenance. Builders like Z1 Motorsports have documented similar figures across their own Z car projects.

What Breaks First

Synchros tend to wear first, especially on early units without the triple cone upgrade. After that, the input shaft is usually the next weak point under sustained high torque.

Upgraded Internals

Aftermarket synchro kits and stronger input shafts exist for builders pushing past stock limits. Some shops also offer billet shift forks and hardened dog rings, which help the transmission hold up better under repeated hard shifts. These upgrades cost more, but they're often cheaper than replacing the whole unit later.

CD009 vs T56: Which Is Stronger?

The T56 generally handles more torque out of the box, but it comes with longer gear ratios that aren't ideal for track driving. The CD009 trades some raw strength for tighter gearing and lower cost, which is why so many drift and road course builds still choose it over a Tremec unit.

CD009 Swap Options

LS Swap

The CD009 is a common choice for LS swaps thanks to widely available adapter kits. Fitment is well documented, so this is one of the easier swap combinations to source parts for.

2JZ Swap

Pairing a CD009 with a 2JZ takes more planning since the bellhousing bolt pattern doesn't match natively. If you're weighing swap options more broadly, our 2JZ and RB26 builds comparison covers how each platform handles power differently, which matters when picking a transmission to match.

RB Swap

RB swaps face a similar bellhousing mismatch as 2JZ builds. An adapter plate is required, and clutch alignment needs extra attention during install.

Adapter Plates, Clutch and Flywheel

Whichever engine you're pairing, budget for a quality adapter plate, a matched clutch, and a flywheel built for your specific bellhousing. Skipping on these parts is one of the most common reasons swaps fail early.

What a CD009 Costs in 2026

Used vs New OEM

Used CD009 units typically run a few hundred to just over a thousand dollars depending on condition and mileage. New OEM units are harder to find and cost significantly more when available. Browsing JDM Florida's transmission stock is a good way to compare current pricing on tested units.

What to Budget for the Full Swap

Beyond the transmission itself, plan for the adapter plate, clutch kit, flywheel, and labor if you're not doing the install yourself. Shipping and any core charges can add a bit more on top, especially if the unit is coming from out of state. A full swap budget usually lands well above the cost of the transmission alone.

What to Inspect Before You Buy a Used CD009

Check for smooth shifting through all six gears, listen for grinding on cold starts, and inspect the casing for cracks or leaks. Pull the fill plug if possible and check the fluid for metal shavings, since that's often a sign of internal wear. Pay close attention to 5th and 6th gear, as those tend to get notchy first on higher mileage units. Ask about mileage and whether the clutch has already been replaced, since that affects how soon you'll need to budget for one.

Frequently Asked Questions

How much HP can a CD009 transmission handle?

Most builders report reliable use up to around 500 to 600 horsepower with stock internals, though this depends heavily on driving style, clutch choice, and maintenance.

Is a CD009 stronger than a T56?

Not quite. The T56 typically handles more torque, but the CD009 offers tighter gearing that many drivers prefer for track and drift use.

Which cars came with a CD009 transmission?

The Nissan 350Z, 370Z, Infiniti G35, and Infiniti G37 all used the CD009 across various model years.

How much does a CD009 cost?

Used units generally range from a few hundred dollars to just over a thousand, depending on mileage and condition.
