100% OEM Authentic Nissan Parts
Eliminate transmission grind and restore buttery-smooth shifts with this Genuine Nissan OEM 3rd Gear Assembly. Specifically designed for the early-model (2003–2005) Nissan 350Z 6-speed manual transmissions (FS6R31A), this brand-new factory gear replaces worn, chipped, or damaged internal components.
Early 350Z manual transmissions are notorious for premature synchronizer wear and gear engagement issues. Rebuilding your transmission with genuine Nissan components ensures exact tolerances, correct hardening, and precise tooth mesh, saving your transmission case from catastrophic internal failure.
Why Choose Genuine Nissan OEM?
Perfect Tooth Mesh & Fitment: Engineered exactly to factory specifications to minimize gearbox whine and guarantee flawless power transfer.
High-Tensile Steel Construction: Manufactured to endure aggressive high-RPM shifts and track abuse.
Restore Driving Comfort: Helps eliminate the dreaded 3rd-gear grind common to early Z33 chassis manual gearboxes.
### Vehicle Compatibility
Chassis: Nissan 350Z (Z33) Pre-Facelift Models
Production Years: 2003, 2004, 2005
Transmission Type: 6-Speed Manual (FS6R31A)
💡 Transmission Builder's Tip: When opening up your early 350Z gearbox to replace 3rd gear, it is highly recommended to inspect and replace your synchros, seals, and bearing kit at the same time to guarantee a complete, long-lasting rebuild.
