2nd Gen Rogue CVT reprogram (PC 490)

[tutor772]

(I apologize if this has already been posted--couldn't find it with a search.)
I had my 2014 Rogue in today to replace the fuel pump under the recall campaign. When I dropped the car off, the service writer said Nissan had issued a "service campaign" one week ago to reprogram the transmission control module (TCM). He was a little vague about the reason for the service campaign, other than Nissan had received enough complaints about CVT shuddering on deceleration to warrant reprogramming. As best I can tell, the Nissan ID for the campaign is PC490, and the bulletin is NTB16-121. Someone who has access to the TSB might be able to share more information.
I can't say that I noticed any difference in how the transmission behaved on the drive home.

I just left my car at dealer for this cvt software update. Lets see if it makes any difference

[RODOSFL]

Just drove home with the new reprogram done along with an oil change. The things I noticed: 1. I did feel a noticeable difference with the ECO mode; it had less of the rubber band feeling and more of a controlled acceleration because of it. 2. When I turned eco mode off (regular drive) I felt the vehicle less springy when accelerating. (sorry for the word springy not sure how to define the feeling) If you own this vehicle you know the feeling when you accelerate after turning off ECO Mode. This is possibly due to the controlled acceleration mentioned above. I came online to see if anybody else reported any changes. I'll have to drive it around some more and report back. Hopefully someone else has some input on what changes were done.

I heard from other forum that the software update doesnt really change drive-ability of the vehicle. It just enables the car to store error code from cvt so that dealers can read codes when we take our car to dealer to cvt problems

I picked up my car from dealer and transmission feels the same as before. no difference.

Had the CVT reprogrammed today. Noticed a remarkable improvement in acceleration from 0-20mph. Not sure if it's all in my head but I'm happy with it.

This makes me wonder if dealer didnt reprogram the cvt in my rogue and returned the car as it was before. I have an other appointment next week. i will ask him

Along with quite a few others, I have inquired on this forum about any knowledge of the bucking/vibrating/shaking that happens between 1500 rpm and 2500 rpm in Eco or Normal modes, especially when going uphill.

I have been living with this for 2 years (have a 2015 Rogue SV) and initially thought I was doing something wrong, but read some of the posts on this forum and found I wasn't alone.

During a visit to the dealership's service department today, I again mentioned the vibrating. The service manager informed me that there is a notice on this problem (I don't remember if he said it is a "recall" or a "service bulletin"). Who cares ? at least Nissan is admitting there is a problem and are trying to fix it.

The service manager called it "Jutter" and insisted that when scheduling my appointment I mention the "Jutter" problem so that it becomes a part of the record and will be a warranty issue.

I'm thinking "jutter" may be Asain for "shudder" or "stutter" ???

Had to post this, since so many people said they had this issue. Get to your Dealership !!!

As it was explained to me, Jutter is a transmission problem. On the first visit, they will install some software to allow them to diagnose the problem. The manager claimed they had no way of diagnosing the problem up until now. Then they will try changing some part. He named the part, but I was not paying attention. Then if the part doesn't work, they change the transmission.

Good Luck Everyone

Everyone on this forum with a 2nd gen Rogue cares, thank you. It's called NTB16-121 Service Campaign to be precise, and it's discussed in this thread, which is why I've merged your post into it.

[BarbraNJ]

Thank you, I must have missed this thread.

I see that a few people have had the "reprogramming" and said that they felt no difference. I got the impression from my service department that there will be no change with the reprogramming, it is merely an additional diagnostic tool for Nissan to collect data on the problem. Perhaps they don't even have a fix yet, since they're still collecting information on the problem.

At least they acknowledge that it's a problem (after 2 or more years of complaints, of course).

I got the update when I was at the dealer this week for an oil change and I don't really notice much of a change in behavior.

[Iteachyoumath]

I got the reprogramming done and saw a noticeable change when coasting downhill. Transmission does not wind up and stay at high rpm's as long. Seems much smoother.

I was in the dealership back in December and they did not mention any active campaigns even though I asked if they could check and make sure I am up-to-date on any other software updates, recalls, etc. They said I was up to date at that time. Fast forward to this month and I get a letter from Nissan that says there is a free service campaign for updating the CVT TCM firmware to resolve a potential belt slip issue that could cause premature wear and eventual failure.

I'll hit them up next week for the 1hr service time and report back what I learn/observe.

FWIW: I had this same dealership do the factory CVT fluid drain/replace (~$130) at 31K miles just to be prudent. I plan on repeating this at every 30K mile interval with the OEM fluid by their technicians for proof of service.

I just got back from getting an oil change on my 2015 Rogue and they performed the NTB 16-121 2nd Gen Rogue CVT update.

I wasn't expecting to feel any difference but boy was I wrong! There is definitely a difference. Feels a bit more peppy and the "loudness" of the transmission while driving is reduced dramatically! It no longer sounds like a Diesel at certain RPM's

I thought it was in my head so I called my good friend who is a Service manager at Nissan. He says I am right, the update does change how the CVT operates and making it quieter is one of the things they fixed. He says it is not published because Nissan will never officially admit the CVT was loud before (Marketing thing) but he congratulated me on having the ears to notice. He says 99% of the customers don't even feel or hear a difference.

This update is highly recommended!

Got mine back now after the CVT TCM update. Don't have a lot of miles on it yet, but I can't really tell any difference. Keep in mind however that I was not experiencing ANY problems beforehand. I've got to get more drive time on it to really test it (will do that in the next few days).

The difference you are noticing is mostly likely due to oil change. New oil sweeps freely and give you that feeling. Update has nothing to do with the way CVT operates. The update just adds a function that stores future trouble code related to CVT in ECU.

I hear you and this is what i've read on-line. But like I said, Internally my Buddy says there is a lot more to it. The whole "stores trouble codes related to CVT" was what Nissan publicly says to save face.
My buddy is a Service Manager at Nissan says there's a lot more to it. Better Fluid flow etc... Nissan will never admit this publicly though, it will make it seem like nissan was selling a car with faulty tyrannies.

I took my 2015 Rogue in last week for the NTB 16-121 update and can tell a big difference in the vibration that was prevalent at low speeds (<25mph). Since this is my wife car and I only drive it occasionally, I haven't paid much attention to the "preppiness" of the engine.
