Parts for your 2019 Mitsubishi Asx-Cluth slave cylinder

2019 Mitsubishi ASX cluth-slave-cylinder: do you have one, and what does it do?

Based on technical references such as the Mitsubishi Motors GA-series ASX/RVR/Outlander Sport Workshop Manual (Clutch section) and Australian/NZ parts catalogues from major suppliers, the 2019 Mitsubishi ASX fitted with the 5-speed manual gearbox uses a hydraulic clutch system with a master cylinder and an external clutch release (slave) cylinder mounted on the transmission bellhousing. CVT-equipped ASX models don’t use a clutch or a cluth-slave-cylinder at all, so the part isn’t relevant to those vehicles.

On manual 2019 ASX models, the clutch slave cylinder is the hard-working bit that converts pedal pressure into movement at the gearbox. Press the clutch pedal and the master cylinder pushes fluid down a line, the slave cylinder then moves the release fork to disengage the clutch so gears slip in smoothly. It’s a simple, reliable setup, but like any hydraulic part it lives a tough life near heat, road grime and moisture, so seals can get tired over time.

Owners and workshops will typically keep an eye on a few tell-tales. A clutch pedal that feels spongy, sticks low, or slowly sinks can point to internal leaks. Difficulty selecting first or reverse, or a bite point that suddenly changes, is another red flag. And any dampness around the slave cylinder, the line fitting, or the bellhousing window is a cue to act sooner rather than later.

For day-to-day care, it pays to:

• Check the shared brake/clutch fluid reservoir periodically and top up with the specified DOT 3 or DOT 4 fluid (as shown on the cap). Avoid DOT 5 silicone fluid.
• Inspect for weeps at the slave, hose and fittings, even a light film means the seals are on the way out.
• Flush the clutch hydraulic fluid about every 2 years, the same cadence most brake systems follow in Australia and New Zealand.

When replacement’s on the cards, a quality new slave cylinder is generally a quick bolt-on job: disconnect the line, swap the unit, fit fresh sealing washers if used, then bleed the system until the pedal’s firm and the fluid runs clear and bubble-free. It’s smart to inspect the flexible hose and the master cylinder at the same time, if the system’s been contaminated or run low, doing the master and slave together can save a repeat visit. After bleeding, confirm smooth gear engagement and a consistent pedal feel on a short test drive.

If the ASX in question is a CVT, there’s no cluth-slave-cylinder to service or replace—the transmission doesn’t use a conventional clutch, so any clutch hydraulics simply don’t apply.

Popular questions about the 2019 Mitsubishi ASX cluth-slave-cylinder

Does a 2019 ASX with CVT have a cluth-slave-cylinder?
No. CVT models don’t have a manual clutch, so there’s no slave cylinder fitted. The cluth-slave-cylinder info here applies only to manual-transmission ASX vehicles.

What are the common signs the cluth-slave-cylinder is failing?
A soft or sinking pedal, difficulty selecting gears (especially first or reverse), visible fluid leaks around the bellhousing or slave, and a bite point that wanders are the usual symptoms. Air in the system may mimic some faults, so a proper bleed test helps confirm what’s what.

How often should the clutch fluid be changed on a manual ASX?
Every two years is a good rule of thumb in AU/NZ conditions. The clutch shares similar fluid and moisture concerns as brakes, so periodic flushing keeps corrosion at bay and the pedal feel consistent.
