Parts for your 2010 Honda Stream-Cluth slave cylinder

2010 Honda Stream cluth-slave-cylinder — is it used?

For most 2010 Honda Stream models (RN6–RN9), a cluth-slave-cylinder isn’t fitted because these cars were predominantly sold with a 5‑speed automatic gearbox. Automatic transmissions don’t use a manual clutch, so there’s no hydraulic clutch circuit and no slave cylinder to service. This aligns with Honda’s workshop literature for the RN6–RN9 chassis and the official Honda electronic parts catalogue (EPC), which list clutch master/slave components only against manual transmission variants.

Why it’s not used comes down to how the driveline’s built. The 2010 Stream’s auto uses a torque converter and internal clutches managed by the transmission’s hydraulics and control unit. There’s no pedal-operated clutch, so a cluth-slave-cylinder simply isn’t part of the system. In Australia and New Zealand, most Streams on the road are ex‑Japan imports with auto transmissions, so talk of a cluth-slave-cylinder generally won’t apply.

There were limited manual-transmission Streams in some markets. If someone has one of those rarer manuals, then yes, it will have a hydraulic clutch with a master cylinder at the pedal and a slave cylinder mounted on the gearbox bellhousing to move the release fork. A quick way to check what’s in the driveway:

• Two pedals and a PRND gate on the shifter = automatic, no cluth-slave-cylinder.
• Three pedals and a traditional H-pattern shifter = manual, cluth-slave-cylinder fitted.

For manual owners: typical signs of a tired cluth-slave-cylinder include fluid loss around the bellhousing, a spongy or sinking clutch pedal, difficulty selecting gears, and dark, contaminated clutch fluid. Routine care is simple — inspect for leaks, make sure the rubber boot isn’t torn, and bleed/replace the clutch fluid (same reservoir type as brake fluid, DOT 3 or DOT 4) roughly every two years or 40,000 km, whichever comes first. If the slave’s leaking or sticking, replacement is straightforward for a competent technician: swap the cylinder, torque the fasteners, and bleed the circuit properly to restore a firm pedal.

Technical basis: Honda RN6–RN9 workshop manuals detail the hydraulic clutch only for manual models, and the Honda EPC lists slave cylinder part numbers exclusively under manual transmission fitments. For the widely sold 5‑speed auto Stream, no clutch slave cylinder is specified.

• Does a 2010 Honda Stream have a cluth-slave-cylinder?
  Most don’t. The common 5‑speed automatic has no cluth-slave-cylinder. Only the rare manual versions use one, with a clutch master and slave working together. If there are just two pedals, it’s an auto and this part doesn’t apply.
• How can someone confirm if their Stream needs a cluth-slave-cylinder?
  Check the transmission: three pedals and a manual shifter means the car has a hydraulic clutch with a slave cylinder. They can also run the VIN through a Honda parts system or ask a technician to visually check the bellhousing for a small hydraulic cylinder with a bleed nipple.
• What maintenance is recommended for a manual Stream’s cluth-slave-cylinder?
  Keep an eye out for leaks, make sure the dust boot’s intact, and flush the clutch fluid with DOT 3 or DOT 4 about every two years. If the pedal feels soft, the gears baulk, or fluid keeps dropping, the slave may be due for replacement and a proper bleed.
