Apparently Jatco has gone with a chain as opposed to their typical belt on some of the JF017E units used with VQ35 engines. I didn't know this. Sorry if it's been posted.

Unfortunately, it's only a matter of timer until the MT goes the way of the dodo.

Just to add to the above. The chain has been used since the 2013 Pathfinder came out, thus the 5000lb towing capacity of the 2013-2016 model years and 6000lb for the 2017+. 2017+ got the extra 1000lbs due to the direct injected engine.

Do the pathfinders suffer from the chronic CVT problems that the rest of the lineup does?

From a fella on the Pathfindertalk site:

"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."

I saw one video online where someone dissected a failed CVT out of an older rogue and , while the metal belt failed, it was determined that it was small ball bearings inside the pump that failed. Could be similar.

But it's definitely not a change made to the smaller units right? I really could see myself picking up a mirage with a CVT or a Versa note with a CVT as a small DD / runabout vehicle. I just wouldn't want to have to scrap the thing with a $7000 CVT fails.

I think that's how it goes with this. It's not the belt or chain that fails, it's other components that cause a fluid pressure loss, which causes slack in the belt, then more wear.. until it snowballs to the point of failure. I feel that fluid changes early on and then done regularly help the above, but then you hear of units going 200K miles with no fluid changes. As much as I don't mind CVTs, I'd avoid a Versa with one. You don't seem to hear of issues with CVT powered Mirages, but there's so few of them out there compared to Nissans.

Yep, same here. I'll never buy anything but manual transmission vehicles new.

For those that are too lazy to drive a stick they should buy a traditional geared automatic box, NEVER a CVT.

The US military decided back in the early 80s that it was a huge waste of resources training recruits to drive manuals.
Also that some of the women coming in were smaller and struggled with the force and reach of a truck clutch pedal.
So we've sold a LOT of Allisons to them in the years since.

Yep, the higher ups at work haven't ordered a new over the road tractor without automatic in a few years now. I'm not sure if it's a cost, personnel or fuel savings thing? I know the truck drivers hate them. They buy mostly bottom of the barrel Freightshakers with the 10spd auto.
