2010 Altima 2.5 S
Im replacing the cvt fluid and during the discovery phase of how to do it, I learned that Rogues, Muranos, Pathfinders... Honda cvt's.. Mitsubishi cvts... have a internal mesh filter and an external fine filter. After learning this, it made no sense why Altimas would not also have an external fine filter. Several hours later I discovered that Altimas do have an external fine filter and it is possible to replace it.
The parts required for fluid flush and filters is attached pic. The internal mesh filter o-ring is one of the parts posted. The plan is to clean the original mesh filter and reuse it. The two copper crush washers are for the trans inlet tube attached to the Cooler Filter Housing (see pic) where the fine filter is located. It would be easier to remove the Cooler Filter Housing with the tube also removed, although not necessary.
I tried to attach the Valve Body TQ sequence but it would not let me. Its a very good idea to check them.
Valve Body half bolts to 70-108 in. lbs. in sequence
Cooler Filter Housing - 4 small bolts - Torque bolts to 37 In. Lbs.
CVT Internal Mesh Filter - 70 in. lbs
CVT Transmission Pan - 70 in. lbs
Forgot to mention, in the parts pic their is a Murano/Maxima cvt filter. This is going to be installed before the Altima Cooler Filter and will be changed every 30k miles so that the more difficult Cooler Filter does not need to be. I looked into all the popular plastic inline filters with small magnets and am not comfortable with those. They are prone to leak, use a paper/cellulose filter and should be changed annually as the paper element does break down.
Update 1: The Cooler Filter, 31726-3JX0A, the dealership provided is the wrong. I "think" the correct filter part is 31726-1XF00. The Cooler Housing O-Ring is also wrong. See attached pic. Its Sunday and dealership is closed, cant get correct parts today.
The old cooler filter and mesh screen looked good. A few small metal pieces in the mesh screen and some pieces of gunk, all very small. Decided since its all apart to change both filters and NEVER change them again. But, I will still use the Murano filter and change that every 30k miles.
Good news, I removed 6 quarts of NS-2. 4 1/2 from the dipstick tube last evening. I let the car sit over night and removed another 1 1/2 this morning from dropping trans pan. It will be interesting to see how much new fluid it will require to flush system.
