Why is my Nissan Z hard to shift into second gear?

Short answer: Some notchiness into 2nd is normal on a new Z, especially cold, and owners say it eases with miles and a slightly slower shift. A real grind (gears clashing) is different. Early 2023 manuals had a Nissan quality action for second-gear grind, so if yours is a 2023, ask the dealer to check your VIN. Report a grind while you're under warranty.

Symptom: The shifter feels notchy or blocked going into 2nd (and sometimes 3rd), you have to force it, or you hear a grinding noise, mostly on upshifts and when cold.

What to check first

1. Note if it's worse cold and better warm.
2. Try a slightly slower 1-2 shift with the clutch fully down.
3. Listen for actual gear grinding vs. just a notchy feel.
4. On a 2023, ask the dealer to check your VIN for the manual transmission quality action.
5. Have the clutch release checked if it grinds in every gear.

Likely causes

1. Early-2023 manufacturing issue. Owners on the Z forums discussed a Nissan quality action and stop-sale on early 2023 manual Zs for a second-gear grind, where affected transmissions were replaced.
2. Stiff synchros when new or cold. Synchros are rings that match gear speeds so the shift goes in smoothly. Owners say the Z is notchy when cold and loosens up with miles. One said theirs smoothed out around 3,000 miles.
3. Shifting technique or clutch release. Several owners found a sweet spot: a slightly slower, deliberate 1-2 shift goes in smoothly where a fast one grinds.

What it usually costs

Under the quality action and warranty, owners didn't pay. Out-of-warranty prices weren't posted.

Is it safe to keep driving?

Notchiness is safe to drive with. A grind that gets worse or popping out of gear needs a check, since it can damage the transmission.

DIY or shop?

Changing shifting habits and letting it warm up are DIY. Transmission and clutch diagnosis are shop work.

Recalls, bulletins and complaints in plain words

• Recalls: NHTSA lists 2 recalls for the 2023-2024 Z: 23V725000 (front bumper reinforcement clip fasteners can keep the pop-up hood from deploying) and 24V798000 (pedestrian detection sensor connectors may be reversed). Neither is about the transmission. The second-gear grind fix was a Nissan quality action, not an NHTSA recall. Check your VIN at nhtsa.gov/recalls. If your car is part of a recall, the dealer fixes it for free.
• Plain words: The complaint count below shows how often owners reported problems that mention these words to NHTSA. A count is not proof of a defect.
• NHTSA complaints: 0 keyword-matched complaints for Nissan Z 2023–2025 (of 5 unique complaints queried, NHTSA complaints API by model year, queried 2026-11-02; keywords: grind, shift, gear, transmission, clutch, synchro) (NHTSA returned no data for 1 model-year queries). This counts complaints that mention these words. It is not a defect finding.

What owners report

• In 2nd gear issues on Reddit r/RZ34, a 6MT Z owner said the 1-2 upshift was so slow and notchy they had to crawl away from lights, though 3-2 downshifts were easy. Others said theirs needed to warm up, that it smoothed out around 3,000 miles, or that a slower shift with the right timing goes in easily. One mentioned a 2023 recall, and their 2025 had no issue.
• In Anyone had any issues with shifting? (6MT) on Nissan Z Club forum, a 2024 Z Performance owner described a notchy, audible shift into 2nd and 3rd, even when warm, much worse than other rear-drive manuals, and less noticeable when shifting slowly. The thread grew to many pages of owners comparing their cars.
• In Manual Z Quality Assurance STOP SALE for 2nd GEAR GRIND on New Nissan Z forum, owners discussed Nissan's quality assurance stop-sale for early 2023 manual Zs with a second-gear grind.

Quick tip

A notchy shift is part of the Z's character when new. A grind isn't. Get that documented under warranty.

Vehicle focus: Nissan Z (RZ34) with the 6-speed manual, 2023-2025.

Safety / mechanic note

A transmission that pops out of gear can be dangerous. Verify with a mechanic.
