CVT Replacement Transmission

[Alyssads921]

I own a 2009 Rogue (SL AWD). CVT transmission needed to be replaced after 2 years and 33,000 miles. The replacement transmission makes a whining noise when comes to a stop. After a month at our local nissan dealership, we were told by Nissan the noise is normal noise due to CVT transmission replacement. This does not seem right.....when we first brought our car to Nissan it did not make this sound. Has anyone else had this problem?

[maverick_rogue]

I drive 2009 Nissan Rogue FWD and have similar issue. An year back @ 20000 Miles Nissan replaced the CVT and since then car makes a whining noise while slowing down (between 30 to 20 MPH). It also jerks at around 17 MPH , probably Torque Convertor disengages at that speed.

What I do notice is that this doesn't happen when car is warming up ( in morning) or when weather is cold.

That's a bit of a tough question, I'm not sure how loud this whining noise is. I know my CVT makes a bit of subtle noise when coasting to a stop that seems to be unique and I guess could be described as a whine, but you really have to listen carefully and it is not alarming. If you have a loud whine then this is definately not normal.

I don't understand why your dealer would say that your CVT should sound differently after the transmission was replaced, unless the unit they replaced it with is a slightly different design that makes a whine noise? Speculation aside, I had my CVT replaced over 2 years ago and it sounds the same as before but minus the rattling noise that I used to have!

If your deceleration noise is very subtle and you have to strain to hear it I don't think I'd be concerned but I'd really have to hear the noise to be confident in my recommendation.

[Alyssads921]

The noise happens EVERY time you decelerate (between 30 to 20 MPH). It is not super loud but you can hear it. I also would not understand why my dealer would say my CVT would sound differently after the transmission was replaced. They did say Nissan is always changing things around so that could be the reason and this noise was going to be "normal" in some rogues. What I don't understand is when I gave them my car it did NOT make that noise with the first transmission. In fact, they were not sure why it made that noise so they contacted Nissan techs who told my local dealership to replace the transmission again (so now this is my third transmission), still couldn't figure it out, changed the transfer cable, still made the noise, replaced an axle after almost 4 weeks there sent a Nissan representative out who told my local dealership it was a "normal" noise for CVT transmissions that have been replaced. Not only does my car still make this noise, it is running worse than when we first brought in the car :-( That is why I wanted to know if anyone else was having this same problem and if so what is Nissan telling them or doing about it. My car is only 2 years old and still under warranty.

[kerrton]

I wish I could offer more input.....just a reminder that you have a 10 year, 200,000 km warranty on the CVT so at least you don't need to worry about the warranty running out after 5 year or less and leaving you with a big repair bill, but I know that doesn't help you today...

[Alyssads921]

Thanks.... but no it doesn't help because our Nissan dealership told us there is nothing more they can do for our car.

Reading the forums, I believe I came across a similiar situation as yours. A customer complaining about a noise not heard before so they asked the mechanic or service manager to drive a couple of new Rogues on the lot to compare to the customers. Eventually they could tell a difference, I I believe they change the CVT to fix it.

You should ask them to drive in a couple of new Rogues with them, then ask if they think they sound the same.

I really hate the run around. I think a customer knows when their fairly new car sounds funny and is not right. Hope you get a fix because a funny noise would drive me crazy.

I personally think with the windows closed and even open for that matter, the Rogue is really quiet to me at least.

I also know if I open the window and stick my head out as if I was trying to get the breeze through my hair, I can hear a kinda peppy noisy engine which I assume is the 4 cylinder doing its thing. I know it may not be your situation, but if you really want to hear a noise, your ears will tend to hear it.

The noise happens EVERY time you decelerate (between 30 to 20 MPH). It is not super loud but you can hear it.

My Rogue also makes the characteristic whine during deceleration at these speeds. And yes, it is a bit more noticeable than when new. A few other owners of Rogue's and other Nissan CVT equipped vehicles have commented about the whine. It appears to be characteristic of the transmission and is not indicative of a problem.

I now have 80,000mi (134,000km) and I am still on my original CVT. This transmission has never given me a problem and runs as well as the day I bought it. Yes it does make some unusual noises at times, but this is mainly due to the nature of the CVT.

My Rogue had a whining noise between 25 and 35 but it was at very light throttle. Took a couple of times till they admitted that they heard it. They replaced the CVT and the noise is gone. Quiet going up or down. absolutely no noise. and strangely my gas mileage has gone up 3 miles per gallon. Keep on them.

[Alyssads921]

The dealership ADMITTED they hear the noise from the beginning, in fact our local dealership told us they had never heard anything like it before. Nissan technical advisor stated the noise heard is "normal" for the CVT transmission due to new gears and design. When we gave them the car with the original CVT transmission,it did NOT make this noise. After a month of them having the car, the car drives worse than when we first gave it to them. I have never heard of any other car making noises that can not be fixed. We have filed a complaint with Nissan and so far their response is there is nothing they can do about it.

[casperfun]

If drives worse? How so?

Anyways, you should look into lemon laws within your state because it seems your standard of quality and performance of your vehicle does not live up to your expectations.

So far my 2009 is on its original CVT with no problems, but you bet I would raise a storm if I had the CVT replaced and it makes a whining noise while going to a stop!

[bembol]

How many Rogue's CVT Transmission has been replaced?

My father's '08 SL FWD, problem started with the Shifter locking up and I started hearing this winding noise so we took in. After 30 minutes I was told the CVT has to be replaced.

He's not happy and I fee like sh*t because I recommended it.

[AZhitman]

It's not eligible under the lemon laws.

However, I'd seek the opinion of a second dealership. Keep us posted, and we'll help as best we can.

My guess is the whining is the final drive or differential (two names for the same stuff). I don't see how the CV part of the Transaxle could really make that whine. When you let of the gas the transmission turns the final drive (instead of the normal way, the engine spinning it) and if the backlash (play in in gears) is not quite right the gear teeth don't mesh up perfectly (as the teeth are touch on the gears) and then you get that whine.

[seraphg]

I have the whining noise too but that happens only when I drive highway with many up/down hills. The noise at that time was pretty much loud so after testdrive with technician the dealer decided to replace my CVT next week. Really not sure what will happen after that, just hopefully I'll be lucky enough to get a good new CVT without any problems then.

[ImStricken06]

this topic has been discussed plenty on many threads. its a very common sound in CVT's. all types of CVT's.
im not sure if its the gearing, belt, cones, etc. but its there, and gets louder as temps increase either due to driving or ambient.
im almost ready to say its normal. i have heard this sound on many types of machines. its common when things are spinning really-really fast.

The voiceover on the video is FIERCE!

Nissan has been putting CVT transmissions in their vehicles since the early 90's. While I'm sure a number of them have failed, I'd be very interested in hearing the PERCENTAGE of them that have failed.

Why? Are you only interested in the fail rate of Nissan CVT's or other brands as well? I should think the better question to ask is which has a higher fail rate, CVT or regular transmission?

[chadhargis]

I have no figures, but I can assume by using my knowledge of each kind of transmission that the CVT would be less durable, but more efficient.

Until I see tractor trailers sporting CVT's pulling 60,000lb loads, I'll conclude that gears are the better solution, but not the most efficient one.

you cant compare the two. trucks that pull 60,000lbs need the gears to be able to withstand the torque loads. a rogue or any other sedan or SUV doesnt pull that amount and doesnt really need that TQ capabilities. that being said the Jatco CVT7 being placed into the Juke does have a few helical gears in the new-structured auxiliary transmission system, the next-generation CVT increases the gear ratio range, and friction-reduction. Which to me is great news. The gear ratio for the 1st gen rogue CVT's sucks. On the highways my RPM's are way to high when its in the final gear ratio available. Id love to have a lower gear ratio that would allow the engine to sit at 1500rpm while doing 65mph.



The Jatco CVT7 - The revolutionary-structure which combines of the belt CVT with an auxiliary transmission (two-step gear change) realizes the world's highest*2 transmission gear ratio. Reduction in pulley size, oil agitation resistance, etc. realize friction cut by 30% compared with conventional CVTs of the same class.

[Rogue One]

With its new-structure auxiliary transmission system, the next-generation CVT increases the gear ratio range, and friction-reduction technology and realizes enhanced fuel efficiency as well as great driving performance, aiming for significantly improved environmental performance as highly expected. Furthermore, the reduction in size and weight expands its applicability to a broader range of vehicles including mini-vehicles and small-sized vehicles.

Introducing the features and the structure of "Jatco CVT7", the world's first CVT equipped with sub transmission.

That's pretty smart. Couple the CVT with what equates to a "high/low" range gearbox.

Doesnt matter the technology put into CVT's. They're belts and belts will stretch and lose it's tightness over time. You can feel a difference when driving a Rogue with 10 miles, compared to a Rogue with 60,000 miles. They drive like the torque converter is slipping at a high rate. The Nissan trucks, Pathfinder Xterra Armada Etc... still don't use CVTs because it can't handle the stress from the motor.

Transmission shops have an easy time replacing the CVT belts because all you need to do is pull out the assembly, use a special tool to separate the cones, and replace with a new belt.

everything is a wear item, including the clutch packs.

[Dave1320]

clutch packs and bands need adjustment over time, but it is the CVTs specifically don't last long. When they get really bad they start bucking and jerking and indicate they're about to go.

Non-CVT transmissions can still drive fine with wear and tear because they have multiple planetary gears and don't break like the belts and pulleys.

planetary gears or not, when the valve body goes - no planetary gears in the world will save hard shifting, and failures to fully engage. when standard automatic transmission's go - slipping, hard shifting(enough to buck), holding gears longer, failure to shift, skipping gears are all symptoms. but thats a convo for a different thread

[kerrton]

CVT Technology is solid and proven over many decades in lightweight applications such as snowmobiles, and more importantly in high torque, high horsepower applications such as Tractors and Combines. We've used CVT-driven combines and tractors for decades and they have been solid and reliable because they were engineered for big torque. Basically, if you have big power and torque, you just design a bigger CVT unit and problem is solved - the result is a big cost, these things are very expensive but the trade off is a durable reliable unit.

Of course the key to anything mechanical is quality of design, manufacture process and materials. If you cheap out and put an undersized CVT with weak materials into a big power situation, yes it probably won't last long but if you design it to handle the stresses of the powertrain and the application anything goes as in the combine example. They could most definately put a CVT into a Nissan truck, but they have to be careful because perception is everything, even if the CVT is bullet proof you still have to convince people of that fact and with so much competition this can be a tough sell.

If you feel the Nissan/Jatco CVT is inferior, fine, thats your opinion and you may or many not be correct. But the fundamental CVT design theory is valid for basically any application including big power and torque and its being proved every day.

My 08 Rogue was effected by the grinding noise issue. I got the patch shortly after it was released in November of 09.

Last week the CVT failed - in traffic - and had to be replaced. It happened shortly after the Nissan extended warranty - that was offered after the patch - had expired. Coincidence???

I am done with NIssan and CVTs forever.
