Cvt bearing noise


Same as most here, doing the helicopter thing as the wife and kids where driving down the Hwy. Will be giving them a call tomorrow to see what they have to say. So far have not found anyone else that has this part but it is after closing, lots of calling to do tomorrow. Just a Royal pain in the ass, thanks for letting me vent here.

Driving down the highway my Ford Freestyle decides to lose all acceleration. The car came to a stop with vehicles behind me traveling at 55 to 65 mph. This could have been a fatal situation. I was able to feather the car off the highway, then the car sat til I was able to get it towed to a garage.

The garage can't even seem to figure out the problem because there seems to be several of them. Other garages have looked at it and said throttle body and electrical part that has gas pedal attached to it.

Track light and abs lights still on. Charging light is now on and still no pedal and now a growl noise coming from the front of the car. If anyone has any ideas please help Everyone is telling me I should have stuck to my Dodge. Car has low mileage because was owned by elderly people who hardly used it. I got it when it had 16, miles and shortly after that I had to replace brakes and tires.

Now at 41, miles I have a very loud whining noise as car is running and louder as I increase speed. Took it to 2 garages and both said it was the transmission and can not be fixed - must be replaced. THis is not a cheap fix. If a transmission with such low mileage even tho has years, should not Ford who knows it is a lousy transmission, accept some responsibility for a fix? But I am given no help from Ford or the dealership. Not a happy camper and not going to be buying another Ford unless they step up to the plate.

This car has been very dependable, now it is having a scary issue with a noise that sounds like a child's choo choo train when in park. The noise stops when the car is in motion. Mechanic thinks it may be my transmission, but he isn't sure and he says he will research and get back with me.

Could it be something other than the transmission? Also, I found the two recalls I did not receive from Ford on your website - re: the door locks freezing I was late for work 2 times and I received no sympathy ; and the issue re: the straps securing the fuel tank.Other wise it functions perfectly. Please advise. Do you. The CVT scrapping or whining noise is the steel belt inside the unit and the bearing the pulley rides on. Unfortunately a software update will not fix this.

Clearly I have not heard the noise but this is a common enough complaint to know the repair is typically a replacement unit. Most places don't rebuild these units because the cost is about the same to replace and rebuild. Plus there are limited parts available to rebuild them. The only other possible cause is if the unit is low on fluid. I attached the process to check the fluid. It is not the easiest process but we need to make sure it is full.

Let me know if you have questions. Thanks Images Click to enlarge. Was this answer. Which TCM should I have used? The old one or the one that came with the used transmission. You would use the one from your vehicle and not the one out of the other vehicle. Basically this is the learned data as it is driven and when you install a new unit you don't want to operate the new unit on the old unit's data. This could effect the drive-ability but most likely will not cause a noise.

Again, I suspect this is an issue with the unit and not just a programming issues even though this should be done, I don't think it will correct your issue. Image Click to enlarge.

Why Is My Car Making Whining Noises?

You are not logged in login. Free Hit Counter. By this I mean broken or unable to move the car due to actual catastrophic mechanical failure eg bearing failure in the transmission, cvt belt failure, broken gears or pulley mechanism, valve body failure etc etc. By this I Don't mean failures of Transmission Management Computer, Shifter mechanism, temporary limp mode problems etc. Many CVT transmissions replaced due to the rattles etc.

The Honda PCX / Forza / ADV150 / SH Forums

Now Nissan are stating, it seems, that in spite of low speed rattles and noises when "Feathering" the throttle ie no drive or retardation engine speed matches road speed that these replaced transmissions have no fault. My second CVT transmission at 60,kms car at 90,kms sounds now like the first when it was deemed faulty and was replaced. The noises and rattles could entirely be due to a little normal wear in the gear train - similar to differential backlash - that is simply not so well controlled by the Transmission Management Computer TCM.

Re: I am not sure what is the logic behind your questions mate! If you are saying that you are happy to live with "non-catastrophic" rattles in your transmission just because someone is going to assure you that your car won't stop in the middle of nowhere, then it is your choice You are paying top Dollar for these cars to expect them to last I reckon it will be a cheaper option and hassle free.

Sorry, but I don't agree with your analogy and I wouldn't expect any other owner to do so either. This type of argument can only come from someone like the manufacturer themselves who will try and do anything to wiggle out of replacing a defective transmission!

Totally agree with your view on the issues raised in this forum and Nissan's abysmal response to owners concerned about the CVT issues well covered here. I thought CVT were replaced out of "goodwill" to satisfy customers regarding NVH noise, vibration harshness and not an actual fault.

I did hear of rumours about faulty material in some early bearing batches but this seemed unconfirmed. Other rumours were about less than ideal TMC control of backlash and a firmware update corrected this sometimes. For this reason I wonder if any CVTs have actually failed, rather than just become noisy when "worn in".

It would be nice to know that in spite of the issues the car is actually just a noisy but reliable vehicle that we otherwise really like and Not a Lemon.

That is the point of raising this question and not with a view of sounding like a Nissan Australia Rep may they. You had something replaced under warranty. You now fear the same part needs replacement again but this time it will be at your own expense. Do you go ahead and replace it or do you just live with the rattle knowing that although annoying it will not leave you stranded one day.

I would want to know the same thing. As for the Hyundai comment- after having seen first hand how they treat their customers with warranty claims I would have no hesitation buying a Hyundai over a Nissan off the showroom floor. Hyundai will actually fly a head office rep to any dealer making a warranty claim to personally assess the situation. No mucking about with phone calls, emails and photos. After all isn't a huge part of the reason we buy new cars the perceived reliability and manufacturer hygrophila spinosa homeopathy medicine via warranties.

Todd: The Hyunday comment was made as a compliment to Hyundai actually.As it has no physical gears or fixed gear ratios it provides an advantages in terms of acceleration, smoothness, fuel efficiency and eco-friendliness. To understand the operating characteristics of a CVT we need to understand why CVTs were developed and what they are designed to accomplish.

The following sections are meant to describe the relationship between an engines power output, gear ratios, and their effect on fuel efficiency. Power is the speed at which energy Gasoline is converted to mechanical forces necessary to propel the vehicle. In simple terms, torque describes how much work an engine can do and horsepower describes how quickly that work can be done. Engines are designed to work over a wide range of engine speeds RPM however the torque and power output do not remain constant.

Within this wide range of RPM, maximum torque is achieved at the RPM the engine is able to move the maximum amount of air and fuel in and out of the engine. This is also the point at which the combustion of air and fuel is most efficient, resulting in lower exhaust emissions. Because power is the speed at which energy is converted, more power or higher engine RPM generally means higher fuel consumption, with some exceptions in a vehicle equipped with a CVT.

There is a compromise between the lowest gear ratio which improves acceleration and the highest gear ratio which improves fuel economy. An ideal transmission would have a very low first gear ratio and a very high final gear ratio. However, the further apart the first gear ratio is from the final gear ratio the less responsive the vehicle is at all speeds in between. It is possible to increase the number of gear ratios to overcome these design limitations, however in doing so the transmission becomes more complex, heavier, and contains more components which also increases opportunities for a component to fail.

Under acceleration the engine on a vehicle equipped with a conventional automatic transmission will rise in RPM starting below the range of maximum torque and then pass above it. When upshifting to subsequent gears the same will occur once more. There is a compromise between the lowest gear ratio which improves acceleration and the highest gear ratio which improves fuel economy, in an attempt to keep the engine RPM in this range of efficiency.

This downshifting can be both heard and felt. The reduced power output and delay actually delays acceleration, but we have become accustomed to these sensations and equate them with increased acceleration. A manual transmission has a clutch that mechanically locks the engine output power to the transmission, while a traditional automatic transmission has a torque converter which uses hydraulic fluid to transfer power.

To overcome these losses torque converters are equipped with a lock up clutch that can mechanically lock the engine output to the transmission under certain conditions. This is why fuel efficiency is usually higher on a similarly equipped vehicle with a manual transmission. CVTs differ from traditional automatic transmissions in that they do not have gears that provide "steps" between low and high speed operation.

Instead, the CVT uses a pair of variable diameter, cone-shaped pulleys connected by a steel chain, which transfers all engine power.I have a Ford Freestyle that started making a thumping noise in P and N, but as soon as it is put into gear, the sound goes away. A buddy said it sounded like a helicopter taking off.

Now to my stinking question. If the input shaft and bearing are the only issues, do I even need a new transmission or can someone out there replace just these parts. Thanks 1. Even if it was possible to just replace one or two parts the labor would be so high that it would be a waste of money because you would not have any kind of warranty. And Mr. Tester knows what he is talking about. As for driving further do you really want this thing to fail in front of a Semi-truck?

Thank you very much. Same goes to all others who reply. Thanks a bunch. I just needed confirmation from a couple people that know their stuff. This sucks, but not nearly as bad as if I was questioning whether or not I was being taken advantage of during the process.

The car has k on it, but is a gem besides this issue. Not a fun position to be in but it sounds like you might have a disposable car. A car without an engine or transmission is not worth much, as was told to me anyway. Even in a conventional transmission, its not the parts cost but the labor involved in putting them in, plus once its opened up, might as well replace all the soft parts.

At any rate I doubt other options like a used one are good options so you have to look at the value of the car and would it make more sense to start over with a new car instead of repairing this one? Nobody can get a real diagnosis from simply doing research. Only a true tranny tech with the car in his shop can diagnose and repair your problem. Yes, it is possible that the tech can repair the tranny… but just replacing a bearing assembly involves disassembly that necessitates the replacement of other parts too, as well as fluids and filters, and often finds associated damage.

A tech can diagnose yours and give you your options. Ii recommend a reputable independently owned and operated tranny shop. With a bearing wiped out that bad you can safely assume many other parts are also worn so a transmission replacement is good advice. If regular services are not performed that could explain the damage.

Low fluid level due to a leak could also explain it. If this were a non-CVT automatic transmission, you could probably find someone who can do a repair, but it would likely come with a very short warranty that would make a replacement transmission worth the price. Bing is right. I have a written diagnosis from the Ford dealership.

Thanks for your time. Is that how you reach a medical diagnosis? Are you a loyal Ford customer? Have you bought Fords in the past? Put that in your letter. Will this issue affect your choice of brand on your next car purchase? Give Ford a reason to help you and they just might. Thanks very much.I bought my Nissan Altima about 3 years ago and it had only 58, miles on it now has 67, miles on it.

It has never gave me any issues until this past Saturday it started making this whining noise when I pressed on the gas pedal up hill and coasted down hill and this was during the day in the heat. It didn't make any noise when it was cooler and got dark. Today In the morning it was fine until later on I went to go to Walmart and had to go out in the heat then it started with that whining noise again. Anyone else having these exact problems? Bob answered 5 years ago. Take it to the dealer- or a competent mechanic- maybe there is a way to service it.

Nichole answered 5 years ago. I plan on taking it in the morning to the Nissan dealers. My daddy said it does sound like the transmission is slipping tho but he wanted the dealer to confirm it.

Jayfox86 answered 5 years ago. What did the dealer say? I just experienced the very same issue with my Altima yesterday driving uphill. I pulled over at a gas station for about twenty minutes before restarting and it drove fine. But it feels as if the engine is straining when hitting speeda of 70 or more. Apparently it's the Transmissions bearings are poorly aligned from the factory, and certain ones may have one that's more misaligned and it wears it down somehow and causes that noise.

GuruY69X answered 4 years ago. Have a Nissan Altima 2. Had a horrible whining noise on acceleration and worse when slowed down. Took it in 2 days ago to Nissan dealership and needs a new transmission. They happened to have 1 in stock which makes me think they replace these often. Checked and there is no recall.

I've never really liked this car. Has bad vibration that i thought was the tires but still does it after new ones. I took it in and they said they tightened up something and that should do it. GuruW71V answered 4 years ago.

I have nissan Altima 2. I see lots of guys above have the same issue with CVT. We all should get together in a way and fight back because nissan extended warranty on other newer models from 60, towhy not Nissan Altima too???

His Her answered 4 years ago. Ran into the same issue last week. Transmission issue whining sound, took it to the shop issue is the transmission. A well know issue with Nissan that I'm now finding out. Good luck to all out there.

Dubess answered 4 years ago. Nissan's North American spokesman David Reuter, admits to the issues associated with "a flurry of new-vehicle launches" in Nissan knows about the issues and yet is not doing anything about them. Yes, Nissan extended the warranty for vehicles from but what about us owners? And from reading the comments on the web, it's not just the owners that are having issues.Reason :. I took apart the cvt all the way down, even took the clutch pack out, no parts had any visible wear, and all bearings were pretty tight, any other ideas?

What exactly happens when that clutch pack goes bad, the sound happens upon initial accel, and under load, and when i hit hard bumps, and when i let off, the clutch pack didnt appear to be bad as far as the friction surface goes, but there was definately wear on the sides of two of the little fingers that spread out, not sure how this could make the noise, but i am really out of options other than letting the stealership get ahold of it, and if i end up taking it to someone, can someone recommend a pretty reputable place to get it serviced?
