T4 Gearbox Speedo Pinion (Z-12)

This gearbox speedometer pinion (Z-12) is the 12-tooth drive gear that fits into the gearbox speedometer drive on VW T4 manual transmissions (and listed Sharan I applications). It converts gearbox output shaft rotation into a mechanical signal for the speedometer cable or sender, ensuring accurate road speed and mileage readings.

Worn, damaged, or incorrectly matched pinions are a common cause of inaccurate speedometer readings, jumping needles, or total speedo failure. Replacing the pinion with the correct tooth count (12 teeth) restores proper calibration and smooth operation.

What this part does

• Drives the speedometer from the gearbox output

• Maintains accurate speed and odometer readings

• Replaces worn or damaged original pinions

• Correct Z-12 (12-tooth) specification

Fitting notes & recommendations

• Tooth count must match the original pinion (Z-12)

• Inspect the speedo drive seal/O-ring and replace if hardened or leaking

• Lightly lubricate before installation

• If speedo readings are incorrect after fitment, confirm final drive and tyre size haven’t been changed
