Replacing your factory gear selector with a proper 370z Nismo automatic shift knob changes how your car feels every time you drive. Nissan’s automatic Z models often ship with bulky, uninspiring shift levers that look out of place in a sports cockpit. Upgrading to a weighted Nismo piece adds tactile satisfaction, shortens physical hand travel, and introduces genuine motorsports-derived styling to the cabin.
If you own a 7-speed automatic 370z (RE7R01A transmission), finding the right aftermarket or OEM Nismo knob requires navigating specific thread pitch requirements, button-release mechanisms, and weight distribution. We'll break down the exact engineering, installation steps, and performance differences so you can make an informed upgrade without damaging your center console.
Anatomy of the 370z Automatic Shift Mechanism
Manual Z cars use a simple M10x1.25 threaded rod, but automatic variants feature a push-button locking shaft to prevent accidental gear engagement. This mechanical difference means standard manual shift knobs won't bolt straight onto an automatic shifter without custom adapters or modifications.
The factory automatic shifter relies on an internal vertical plunger rod. When you press the thumb or front trigger button on the stock knob, it depresses this rod, releasing the detent lock so you can shift out of Park or Neutral.

| 2. Inner Plunger : Depresses to release gate lock |
| 3. Thread / Shaft: Secures knob position to lever rod |

When evaluating a 370z Nismo automatic shift knob, you need to confirm whether the unit is designed for direct automatic fitment (incorporating a hollow core or built-in trigger sleeve) or if it requires a specialized adapter kit from brands like Concept Z Performance or Z1 Motorsports.
OEM vs. Aftermarket Nismo Automatic Knobs
Nissan manufactures genuine Nismo accessories, but factory automatic Nismo options for the 370z are rare compared to the ubiquitous manual countersunk spheres. Most genuine Nismo manual knobs feature a solid core that blocks the automatic plunger rod, requiring modification or adapter extensions.
Specialty aftermarket manufacturers fill this gap by machining replicas and hybrid designs that retain the classic Nismo aesthetic—such as the titanium burnt finish, black polyacetal resin, or leather-wrapped aluminum—while engineering an internal bore that accommodates the automatic release button.
Material Comparison
- Polyacetal Resin (Duracon): Stays cool in summer and warm in winter. Excellent grip texture, highly resistant to wear, and popular in authentic Nismo track cars.
- Solid Titanium: Heavy, premium thermal feedback, and features a gorgeous heat-treated rainbow burnt finish. It heats up quickly in direct sunlight, so keep a microfiber cloth handy.
- Leather and Aluminum Combos: Mimics the factory ergonomic contour while adding red contrast stitching to match the Nismo interior gauges and steering wheel accents.
Step-by-Step Installation Guide
Installing a new shift knob on an automatic 370z takes less than fifteen minutes if you have the right tools. Follow these steps carefully to avoid snapping the fragile plastic plunger clip inside the shifter assembly.
- Preparation: Park on level ground, engage the emergency parking brake, and turn off the engine. Shift the car into neutral or second gear to give your hands clearance around the center console trim.
- Remove the Stock Knob: Grab the factory knob firmly with both hands and unscrew it counterclockwise. If it resists, wrap a microfiber cloth around the base and use strap wrenches to break the factory thread sealant loose. Do not pull upward aggressively while twisting, or you might yank the internal release rod out of alignment.
- Inspect the Plunger and Spring: Look down the exposed shifter shaft. Ensure the small plastic spring and push rod are still seated correctly inside the metal shaft. If the spring flies out, retrieve it immediately.
- Fit the Adapter or Extension: If your new 370z Nismo automatic shift knob requires an automatic adapter sleeve, slide it over the shaft now. Secure any set screws gently using a hex key, making sure not to over-tighten and crack the inner sleeve.
- Thread and Align: Screw the new Nismo knob clockwise onto the shaft. Stop when the gear pattern or Nismo logo faces directly forward. If it over-tightens past the center point, use a jam nut or adjustable shim washers to lock it in the correct orientation.
- Test Functionality: Turn the ignition to ACC and test the button release mechanism. Ensure you can freely move the shifter through all gates (P, R, N, D, and manual +/- mode) without restriction.
Common Mistakes to Avoid
- Pulling Upward Too Hard: Yanking the factory knob straight up without unscrewing it destroys the internal plastic clips. Always twist counterclockwise.
- Using Threadlocker Permanently: Avoid high-strength red Loctite on plastic or aluminum shifter threads. If you ever need to remove the knob, you will strip the threads. Use mild blue threadlocker or plumber's tape instead if the knob rattles.
- Ignoring Ambient Temperature: Titanium knobs absorb cabin heat intensely. If you park outdoors in summer, use a steering wheel cover or a small sock over the knob to prevent burns.
Frequently Asked Questions
Can I install a manual Nismo shift knob on an automatic 370z?
Not directly. Manual knobs have a solid base that blocks the automatic push-button rod. You need an automatic-specific version or an adapter kit that provides clearance for the plunger mechanism.
Do weighted shift knobs damage the automatic transmission?
No. While heavier knobs add momentum during manual-mode gear shifts, the actual gear selection is controlled electronically by the transmission control module (TCM) and hydraulically by internal solenoids. The extra weight only affects hand feel.
How do I stop a loose shift knob from vibrating?
If your knob rattles at high RPMs, wrap a single layer of plumber's Teflon tape around the shifter threads before screwing the knob back down. This creates a snug mechanical fit without permanent adhesive.
Will changing the shift knob void my Nissan factory warranty?
Under the Magnuson-Moss Warranty Act, an aftermarket shift knob cannot void your entire vehicle warranty unless the dealership proves the accessory directly caused a mechanical failure in the transmission assembly.
