Parts for your 2010 Nissan Dualis-Transmission filter

2010 Nissan Dualis transmission filter: what’s fitted and how to look after it

Based on Nissan technical literature for the J10 Dualis/Qashqai, a transmission filter is relevant on CVT-equipped models but not on manuals. The Xtronic CVT (Jatco JF011E/RE0F10A) used in 2010 Dualis has two filters: an internal strainer for the pump/valve body and an external cooler-return filter. These are identified in Nissan’s J10 Service Manual (TM–CVT section) and parts catalogues (e.g., CVT cooler return filter 31726‑1XF00 and internal strainer 31728‑1XF0x). By contrast, the 6‑speed manual transaxle (TM–M/T section) carries no serviceable filter by design and relies on gear oil only. This makes a transmission filter a real consideration for CVT Dualis owners, but not for manuals.

For CVT versions, the transmission filter’s job is to keep the fluid clean so the pump, valve body, and that delicate steel push‑belt live a long and quiet life. The internal strainer catches fine particles right where the pump feeds the hydraulics, while the external cooler filter traps debris returning from the heat exchanger. Clean fluid is everything in a CVT, it controls clutches, sheaves, and cooling all at once.

Nissan’s service information doesn’t list the CVT filter as a routine replacement item, it’s typically swapped during CVT repair/overhaul or if contamination is found. That said, plenty of transmission specialists in Australia and New Zealand treat the external cooler filter as preventative maintenance, especially if the Dualis tows, sees lots of city heat, or has ticked over big kilometres. Pairing a fresh cooler filter with a CVT fluid service can help keep shift quality crisp and temperatures in check.

For fluid, the 2010 Dualis JF011E specifies Nissan CVT Fluid NS‑2. Many workshops target 60,000–90,000 km intervals for fluid service under local conditions, checking fluid condition and driving use. When changing the external filter, they’ll also flush the cooler lines, use new O‑rings, and verify fluid level at the correct temperature window. The internal strainer is only accessible with deeper CVT disassembly, so it’s left to major service events.

• Good times to replace the cooler filter: after any CVT overheat episode, metal-in-fluid diagnosis, cooler replacement, or as a precaution with a high‑km fluid service.
• Watch for signs of restriction: delayed take‑off, flare or slip, whine, or a CVT temp warning.
• Always use the correct fluid (NS‑2), keep everything spotless, and confirm level with the proper procedure and temperature.

Popular questions

Does a 2010 Nissan Dualis have a transmission filter?
On CVT models, yes—there’s an internal strainer and an external cooler-return filter. On 6‑speed manual models, no filter is fitted because the gearbox uses splash-lubricated gear oil without a filtration circuit.

How often should the CVT filter be changed?
Nissan doesn’t list a routine interval for the filters, they’re replaced during repair or when contamination is found. Many workshops in AU/NZ choose to replace the external cooler filter preventatively when doing a CVT fluid service around 60,000–90,000 km, or sooner if the car tows or works hard.

Which CVT fluid does the 2010 Dualis use?
The JF011E CVT in a 2010 Dualis specifies Nissan CVT Fluid NS‑2. Using the wrong fluid can affect belt clamping force and valve body operation, so sticking with NS‑2 (or an approved equivalent) is the safe bet.
