I know I've seen very limited info online in regards to the newer JF017E CVTs having a chain as opposed to the belts Jatco has been using for years, but apparently it's a thing on the newer Pathfinders:
I think you are right PoManz, from what i read it's only on the 17 and up, which gives the tow rating and was supposed to be the "fix" for the cvt's poor reliability. I could be wrong i got this 2nd hand from my old co-worker who works with Nissan.
Here is a page from my 2013 service manual. In 2013, the Infiniti JX35 was the sister model to the Pathfinder and only had a 3500 lb. towing capacity because the CVT was belt driven. Maybe that is what you were thinking of.
ALL R52 Pathfinders came with a chain. That is what allowed it to tow up to 5000 lbs and then 6000 lbs (2017+) with the revised suspension and added hp's.
Muranos and Rogues come with a belt and that is the main reason they can only tow 1500 - 1000 lbs.
All R52s have the CVT8 with the chain. This issue has never been the belt/chain, its the pressure control valve in the CVT Oil Pump, which regulates the flow of CVT fluid contracting and expanding the pulleys that the chain is attached to.
The Valve is made out of aluminium and scores easily and sometimes even seizes due to wear from metal particles in the CVT fluid, which then creates the domino effect, pulleys to expend contract correctly, chain slips and bounces, creates more wear with metal particles entering the cvt fluid and gradually it gets worse and worse.
There are after market valves which are made from titanium, to fix this, but you need to basically tear down the whole CVT to replace this $20 part. Hence why Nissan did F.. All about it. There has been new oil pumps designed, to do away with the pressure control valve altogether, and suspect these are in the newer builds, like 17 onwards as this pump was late 2016 design.
It's anyones guess if Nissan started updating the pumps in the reman CVTs for the ones prior to this or if they even used titanium valves, guess we won't know unless they disclose it.
Makes you wonder if all Nissan CVT failures are similar (all models). The root cause is not the belt/chain itself, but the components that control fluid pressure, eventually causing the belt/chain to fail.
Normally I leave 4wd off except in the cold. When 4wd is on and I am making right turns, there is this weird rubbing/skipping noise/feeling when turning. Hard to describe in words. Turning left it is there but not as noticeable. However this is not an issue at all when 4wd is off. Any idea...
Honda calls it Variable Cylinder Management. The service rep here at the local dealer tells me that all of these 3.5's have it. They switch from 2 to 4 to 6 back to 4 to 2 - many times during each trip. I thought this feature was not present, and still can't find any proof that it is present...
I bought this vehicle a few days ago. It's first 9 months and ~22K miles were in rental service. I did it's first CVT drain and fill today. I do them cold and 4qts come out. Here's what the fluid looked like compared to new:
Here is a list of proposed mods:
-K&N Typhoon cold air intake kit (BTW it gives off a very nice sound when revving the engine)
-JET chips MAF sensor
-Maxima throttle body swap (it's 5mm bigger and you can get a remanufactured OEM one for pretty cheap)
-Gutted Cats (cost...
