Parts for your 2014 Mitsubishi Asx-Cluth slave cylinder

2014 Mitsubishi ASX cluth-slave-cylinder — what it does and how to look after it

Technical references from the Mitsubishi ASX/RVR/Outlander Sport Service Manual (2010–2015, Clutch section – “Clutch Release Cylinder”) and the Mitsubishi ASA electronic parts catalogue for GA/GA2W models confirm that manual-transmission 2014 ASX variants use a hydraulic clutch release (slave) cylinder. Aftermarket catalogues from major brands also list a direct-fit slave cylinder for 2010–2016 ASX manuals. CVT and automatic ASX models don’t have a cluth-slave-cylinder, because there’s no manual clutch to operate.

On a 2014 Mitsubishi ASX with a manual gearbox, the cluth-slave-cylinder (often called the clutch release cylinder) is the hydraulic workhorse that pushes the clutch fork to disengage the clutch when the pedal’s pressed. It takes hydraulic pressure from the clutch master cylinder and converts it into movement at the gearbox. If it leaks or sticks, the pedal can feel spongy, the gears can baulk going in, or the clutch may not fully disengage.

Typical signs the ASX cluth-slave-cylinder needs attention include:

• Low or dropping fluid level in the clutch/brake fluid reservoir
• Wetness around the slave cylinder dust boot or line fitting
• Soft, sinking or inconsistent clutch pedal feel
• Difficulty selecting reverse or first when stationary

As part of regular servicing, it’s smart to check for leaks, confirm the pedal free play and feel, and flush the hydraulic fluid every 2 years or 40,000 km (use DOT 3 or DOT 4 as marked on the cap and owner’s manual in AU/NZ). Fresh fluid keeps internal seals happier and helps stave off corrosion.

When replacement is due, it’s a straightforward swap on the gearbox housing. The usual steps are: clamp or drain the line, unbolt the old cylinder, transfer any fittings, bolt up the new unit to spec, reconnect the line, then bleed the system. Bleeding can be done by gravity, two-person pedal bleeding or with a vacuum/pressure bleeder. Keep the reservoir topped up and avoid letting air re-enter. If the slave has failed, give the master cylinder a health check too — tired seals often come in pairs.

Quality parts, clean fluid, and a careful bleed will restore a crisp pedal and smooth shifts on the 2014 Mitsubishi ASX manual.

Popular questions about the 2014 Mitsubishi ASX cluth-slave-cylinder

Does every 2014 ASX have a cluth-slave-cylinder?
No. Manual-transmission models have a hydraulic cluth-slave-cylinder. CVT and automatic models don’t use one, as clutch engagement is handled differently and there’s no manual pedal to operate.

What fluid should be used in the ASX clutch system?
Use DOT 3 or DOT 4 brake/clutch fluid as specified on the reservoir cap and in the owner’s manual. In AU/NZ, DOT 4 is commonly used and is backward compatible where DOT 3 is specified. Change it every 2 years or 40,000 km.

Can a failing cluth-slave-cylinder damage the clutch?
Indirectly, yes. If it doesn’t fully disengage the clutch, you can get hard shifts and extra wear on the synchros and clutch disc. Fix leaks and restore proper pedal feel promptly to protect the rest of the driveline.
