Parts for your 2013 Holden Commodore-Cluth slave cylinder

2013 Holden Commodore cluth-slave-cylinder — relevance, purpose and servicing

Based on Holden VE Series II and VF service information and gearbox documentation for the Aisin AY6 (V6 manual) and Tremec TR‑6060 (V8 manual), the 2013 Holden Commodore with a manual transmission uses a concentric hydraulic release bearing, commonly referred to here as the cluth-slave-cylinder, mounted inside the bellhousing. Automatic models don’t use a clutch or cluth-slave-cylinder at all, as they rely on a torque converter. So the cluth-slave-cylinder is relevant and fitted to manual 2013 Commodores, but not to autos.

On a manual 2013 Commodore, the cluth-slave-cylinder’s job is simple: convert pedal pressure from the clutch master cylinder into movement that releases the clutch. Being a concentric unit, it sits around the gearbox input shaft and doubles as the release bearing. That packaging gives a nice pedal feel and consistent engagement, but it also means the gearbox has to come out to replace it. Holden’s workshop literature also notes the clutch hydraulics share brake fluid from the reservoir, so fluid condition matters.

There’s no fixed replacement interval, but a cluth-slave-cylinder should be replaced if it leaks, grows noisy, or the pedal feel turns spongy. Whenever the gearbox is out for a clutch, it’s smart money to fit a new cluth-slave-cylinder and release bearing together, and consider a new clutch kit and pilot bearing at the same time to avoid doubling up on labour later.

• Telltales of trouble: fluid level dropping in the shared reservoir, dampness at the bellhousing weep area, a soft pedal that won’t hold pressure, difficulty selecting gears, or a chatter/squeal as the pedal is pressed.
• Fluid and bleeding: use quality DOT 4 brake fluid, keep it clean, and avoid letting the reservoir run low. A pressure bleed through the master works best, rapid pedal pumping can aerate the system.
• Fitting tips: follow the Holden VE/VF procedures for removal and torqueing, protect the new unit from contamination, and never reuse a contaminated or heat-marked release face.

With the right parts and bleeding technique, a fresh cluth-slave-cylinder brings back a light, predictable pedal and crisp shifts—exactly what a well-sorted Commodore manual should feel like.

Popular questions

Does every 2013 Holden Commodore have a cluth-slave-cylinder?
Not every one. Manual-trans cars do, using a concentric unit inside the bellhousing. Automatic models don’t use a cluth-slave-cylinder because they have a torque converter instead of a clutch.

What are common signs the cluth-slave-cylinder is failing on a 2013 Commodore?
Look for a soft or sinking pedal, clutch drag making first or reverse hard to select, fluid loss from the shared reservoir, or moisture at the bellhousing. A squeal or rumble as the pedal is pressed can also point to a worn concentric unit.

Can the cluth-slave-cylinder be bled without removing the gearbox?
Yes, bleeding is external via the hydraulic line, so the gearbox can stay in. But if the unit is leaking internally or the bearing is worn, replacement requires gearbox removal because the cluth-slave-cylinder sits around the input shaft.
