Product Information

What This Product Does

The synchro ring works within the gearbox synchroniser assembly to bring rotating components towards matching speeds before the selected gear engages. This product is the ring for first or second gear, not a brake band or dog-tooth component.


Functions

  • Provides friction for synchronising gear speeds during selection.
  • Supports engagement of first or second gear within the specified transmission.


Technical Details

  • Brand: Genuine Porsche.
  • Gear application: 1st/2nd gear.
  • Transmission application: four-speed manual gearbox.
  • Existing product reference: 93030230100.


Symptoms of Fault

  • Crunching or grinding while selecting first or second gear.
  • Resistance to engagement or a need to pause before completing a shift.
  • Gear clash during downshifts.

These symptoms do not confirm ring wear on their own. Clutch operation, linkage condition and gearbox oil can also affect selection.


Why Replacement Matters

A worn friction surface can prevent the synchroniser assembly from matching speeds effectively. Renewing a ring after confirmed wear addresses that component during gearbox repair. Inspect the associated engagement teeth, brake bands and selector components rather than assuming the ring is the only worn part.


FAQs

Will fresh gearbox oil repair a worn ring?
No. Correctly specified oil may influence shift feel, but it cannot restore a worn friction surface.

Does double-declutching fix the problem?
It may ease the symptoms, but it does not renew damaged synchroniser components.

Which reference should I check?
Confirm the recorded part number and the relevant gearbox illustration before ordering, as the supplied product and internal diagram references differ.
