CVT transmission fluid filter assembly for Nissan ??️

This OEM‑grade filter unit protects your Nissan CVT by cleaning the fluid that feeds the cooler and valve body. It captures metal dust, belt and clutch particles, and seal debris. Clean fluid reduces heat, stabilizes pressure, and keeps pulleys, pump, and solenoids working smoothly. A fresh filter is essential during fluid service, after overheating, or when lines and cooler are replaced.

Why you need this part ✅

CVTs create fine wear particles under normal use. Without strong filtration, grit circulates, scuffs the belt and cones, sticks valves, and speeds up fluid breakdown. Replacing this unit helps extend transmission life and maintain crisp, quiet operation.

How it works ⚙️

Inside the housing sits pleated high‑efficiency media tuned for CVT flow. It traps contaminants while a calibrated bypass protects against starvation. Correct O‑rings and quick‑connects lock the circuit and prevent aeration. The result: steady pressure to the cooler and valve body.

What happens if it’s bad ⚠️

• Clogged media: shudder, flare, whine, or limp mode.
• Cracked shell or hard seals: leaks, overheating, burnt fluid smell.
• Dirty fluid: delayed engagement, DTCs for pressure/temperature, premature wear.

Tech tips ?️

Use the specified NS‑2/NS‑3 CVT fluid, prefill the filter, follow flow‑arrow orientation, replace crush washers, and torque fittings. After install, idle in P, then cycle through ranges to purge air; check for leaks. Service interval: 60–90k km (sooner in severe use). This unit complements the internal pan strainer—replace both for best results.
