Terra Firma Automotive supplies genuine Nissan transmission hardware that keeps critical components securely fastened in your Z32 manual gearbox. This speed sensor gear pinion screw is the exact OEM fastener used to secure the speedometer drive gear (pinion) to the transmission output shaft. Manufactured to Nissan’s precise thread pitch, length, and strength specifications, it ensures the speed sensor gear remains perfectly aligned and firmly locked during operation.

A loose, stripped, or missing pinion screw can cause erratic speedometer readings, a non-functional speed sensor, or even allow the gear to spin freely and cause damage. This authentic replacement restores a solid, vibration-resistant hold that maintains accurate vehicle speed signal to the gauge cluster and ECU.

At Terra Firma Automotive we carry these small but vital factory fasteners because they are frequently lost or damaged during transmission work. Whether you are reinstalling the speedometer gear after a transmission rebuild, replacing a damaged sensor drive on your twin-turbo, or completing a full gearbox refresh on your 1989–1996 Fairlady Z or 1990–1996 300ZX, this pinion screw ensures proper assembly and reliable speedometer function.
