Parts for your 2001 Holden Commodore-Cluth slave cylinder

2001 Holden Commodore cluth-slave-cylinder (clutch slave cylinder): what it does and how to look after it

For the 2001 Holden Commodore (VT Series II/VX, plus VU ute), a clutch slave cylinder is absolutely relevant on manual models and not used on automatics. Technical references including the Holden VX Series Workshop Manual (Clutch section), Gregory’s Commodore VT–VX 1997–2002 manual, and the Getrag/Tremec service literature note that the manual transmissions of the era (Getrag 5‑speed for V6 and Tremec T56 6‑speed for V8) use a hydraulic clutch with a concentric slave cylinder (CSC) integrated with the release bearing inside the bellhousing. Automatic variants use a torque converter, so there’s no clutch or slave cylinder fitted.

On a manual 2001 Commodore, the clutch slave cylinder’s job is simple but crucial: it converts the hydraulic pressure from the clutch master cylinder into movement that disengages the clutch. Because the Commodore’s CSC is inside the bellhousing, it pushes directly on the pressure plate via the release bearing. That packaging gives a lighter, smoother pedal feel but means replacement requires gearbox removal—worth planning alongside a clutch change.

As part of routine servicing, it pays to:

• Flush the clutch hydraulic fluid (DOT 4) every 24 months or sooner if it’s dark or contaminated.
• Bleed the system carefully after any work, many VX/VU setups have a bleed point or remote bleeder—follow the Holden workshop procedure to avoid trapped air.
• Inspect for weeping at the bellhousing join, a soft or sinking pedal, difficulty selecting gears, or clutch slip that improves after pumping the pedal—classic signs of a failing CSC.

When the gearbox is out, smart money says to replace the CSC/release bearing assembly, the clutch kit, and the spigot/pilot bearing together. Also check the master cylinder and the hydraulic line for leaks or perishing. Use quality parts specified for the Getrag or Tremec unit fitted to the car, and always torque fasteners to the values listed in the Holden manual.

If the clutch pedal feel is inconsistent after bleeding, recheck the bleed procedure and inspect the master cylinder. Persisting issues often trace back to air in the system or a worn CSC seal. Given the labour to access the CSC, preventative replacement during a clutch job saves hassle down the track.

Popular questions

Does a 2001 Holden Commodore have a clutch slave cylinder?

Yes—if it’s a manual. Manual VX/VT II/VU models use a hydraulic clutch with a concentric slave cylinder inside the bellhousing, as outlined in the Holden VX Workshop Manual and Gregory’s VT–VX service manual. Automatic Commodores don’t have one because they use a torque converter instead of a clutch.

What are the symptoms of a failing clutch slave cylinder on a 2001 Commodore?

Typical signs include a soft or spongy pedal, difficulty selecting gears, fluid weeping at the bellhousing, and a clutch that bites low or improves after pumping the pedal. Any of these warrant a fluid check and likely slave cylinder inspection.

When should the clutch slave cylinder be replaced?

There’s no fixed interval. Replace it if it leaks or the pedal feel deteriorates. Because the CSC is inside the bellhousing, it’s commonly replaced whenever the clutch is changed to avoid duplicating labour. Refresh the clutch fluid every two years to extend component life.
