Internal CVT oil-pan filter for the Jatco JF010E (RE0F09A/RE0F09B) in Nissan 3.5L V6 Murano, Maxima, Altima and Quest with the 22-bolt deep pan and long-tube neck.
If you own a 3.5L V6 Nissan Murano, Maxima, Altima or Quest and the CVT has started to whine, take longer to engage, or run hot on long climbs, the pan filter is the cheapest place to start. This is the internal oil-pan filter for the Jatco JF010E, which Nissan codes as RE0F09A and RE0F09B. It replaces OE numbers 31728-1XD03 and 31726-1XA01 and comes with a pan gasket and O-ring, so one box covers the whole pan service.
The JF010E moves the car by squeezing a steel push belt between two variable pulleys, and the clamping force on those pulleys is nothing more than hydraulic pressure made by the oil pump. Every drop the pump draws comes up through this filter first. That makes the filter the only thing standing between the pump and the fine steel and clutch material that a CVT sheds as it ages. Sonnax lists delayed engagement and push belt slippage among the problems tied to pump flow control on this unit, and a restricted filter produces the same starved-pump condition from the intake side. When flow drops, the pulleys lose clamp, the belt slips, and the slip makes more debris for the filter to catch.
Check the fluid condition and level first, at the correct fluid temperature rather than by the quart. Then drop the pan. A filter that has been doing its job will show debris on the magnet and in the pan, and that tells you a lot: fine grey paste is normal wear, but flakes, slivers or bronze-colored material point to pulley, bearing or clutch damage that a filter alone will not fix. If you are also chasing a flare or a no-power complaint, work through our guide on CVT slipping under load before you spend money on hard parts, and see the Jatco CVT problems and fixes guide for the Nissan-specific failure list.
This filter is listed for the 3.5L V6 JF010E: 2003-2014 Murano, 2007-2014 Maxima, 2007-2012 Altima 3.5 and 2011-2014 Quest. It does not fit the 2.5L four-cylinder, which uses a different CVT. Two checks decide fitment and both are easy to miss. First, count your pan bolts: this is the 22-bolt deep-pan filter, not the 20-bolt shallow-pan part. Second, compare the neck: this is the long-tube, high-inlet version, so if your original has a short neck it will not seat in the pump bore. Cross references include F09-G28-403, 95245, B-428, FK422 and TF633. If your parts do not match, send us your year and VIN and we will check it. You can also browse every CVT part we carry on the CVT parts page.
If the pan shows heavy metal, the filter is a band-aid. Plan on a full teardown with the JF010E master rebuild kit, and if you have pressure-related chatter, look at the RE0F09A valve body with stepper motor.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Count the bolts around the transmission oil pan. This filter is only for the 22-bolt deep pan. The 20-bolt shallow pan uses a different filter and the two are not interchangeable.
No. The 2.5L four-cylinder Altima uses a different Jatco CVT. This filter is for the 3.5L V6 with the JF010E (RE0F09A or RE0F09B).
Yes. The package includes the filter, a pan gasket and the O-ring, so you do not need to buy them separately for a standard pan service.
Use genuine Nissan CVT fluid of the grade your owner's manual specifies for your year (NS-2 or NS-3). Do not use a universal multi-vehicle fluid, and set the level at the specified fluid temperature.
First make sure the old O-ring did not stay in the pump bore and the level is correct hot. If the noise continues, the cause is likely internal, such as a pulley bearing or pump wear, and a teardown is needed.
