Why does my car whine when I take off?

Car Makes Whining Noise When Accelerating If your vehicle makes a whining noise when you are accelerating, a transmission problem is most likely at fault. Whining when accelerating due to transmission problems can be caused by worn-out gears or low transmission fluid due to a leak

Can an alternator make a whining noise when accelerating?

The alternator has several bearings which allow the alternator’s rotor to spin freely. If these bearings begin to fail, you will notice a loud whining noise, which will increase when you accelerate or the car is under heavier load.

Can a throttle body make a whining noise?

Hi, if its indeed the throttle-body from which the whine is emanating, it could be the idle-air-control-valve, usually a stepper motor that controls a valve depending on coolant temperature (also whether the A/C is on or off)

Does the transmission make a whining noise?

If the whining gets higher with the revere, it means that the fluid line of the transmission has been clogged. In most cases, a clogged fluid line points to a more significant issue. On an automatic transmission, if the whine gets louder when in gear, it points to a problem with the torque converter.

Can low transmission fluid cause whining noise?

Low Transmission Fluid: For both manual and automatic transmissions, the primary cause for whining when in gear is low transmission fluid. If the fluid is too low, then the internal components of the transmission are not lubricated properly.

What can a dirty throttle body cause?

When the throttle body gets dirty, it has a direct effect on how smoothly the engine operates. Signs indicating a problem include rough idling, jumpy or sluggish acceleration, poor fuel economy, and stalling. With the use of a throttle body cleaning product, the dirt and debris buildup are easily removed.

Whining sound : Lift off accelerator – Maintenance & Repairs

Whining sound : Lift off accelerator Hi All, I’m having this problem for some time as in while travelling in gear, when I lift my foot off the accelerator, there is this whining noise and its seems to be from the auto tramsmission gearbox….some kind of sharp engine brake noise, very annoying. Car is 6 yrs old. Once I just step on accerelator slightly to keep car going, the sound disappears. I lift off pedal, sound comes back immed. I know its not wheel bearings or belts (both air-con and alternator belts hv been replaced). Hope that some forumers can help feedback what is the cause? ↡ Advertisement Link to post Share on other sites Link to post Share on other sites My timing belt is chain type.

I encountered this problem with my old sub legacy. Whining sound when idling, but sound gone when i accelerate. Can’t remember whether my mech say is timing belt or alternator belt. But its definitely one of these two. But then you say yours happen in any gear…. Mine only happen at idle. So might not be the same problem as mine….

The whine comes on when I lift off accerelator (slowing down) and gone when I step on accerelator. When rev up during idling….no whine. That’s why is puzzling and I suspect is gearbox related.

Edited March 28, 2011 by Donut Link to post Share on other sites Nope, mine is not CVT. Auto transmission oil has been replaced on time per owner’s manual and recently twice at only 40,000 km interval thinking that could be problem. Nope still the same…sigh.

Really need some help!   #1   07-29-2013, 09:34 PM Join Date: Jul 2013 Posts: 43 Likes: 0 Received 0 Likes on 0 Posts Whining noise when letting off the accelerator. Really need some help! I just bought a 2000 Discovery 2, with 212000 miles. So far I’ve done an oil change, topped off the diffs with 85w/90 gear oil, and have fixed a few leaks here and there. I also have lubed up the grease fittings on the drive shafts underneath. All things considered, it runs pretty good. The big issue with my “new” Discovery, is that when I let off the accelerator I get a pretty loud whine that sounds like it’s coming from under the center console. When my foot is on the accelerator, it’s as quiet as can be. It doesn’t slip when it shifts gears, nor is it noisy or clunky. Just whines when I let off the gas. I have yet to inspect the tranny for proper fluid levels, as I have stopped driving it until my new filter kit is here and I can flush the tranny and put some heavy weight gear oil in. I did notice that if I put the transfer case selector in neutral and put the gear selector in D, I can here a noise like something is spinning somewhere. Not sure if that’s normal, but I recall reading that this was not good. I am a noob when it comes to Land Rovers, so I really need some input on what the heck is going on here. When I am cruising down the road, the whine is almost imperceptible, but as soon as I decelerate the louder whine is back. If I put the drive selector in neutral while it’s whining, the sound goes almost totally away. What’s odd, is that in the mornings when I leave for work, it stays quiet for probably 5-10 minutes, then after that it will start to whine. Can someone please help me? I just got my Disco and I love it, but I gotta know what to do about this. Any and all help is greatly appreciated.   #2   07-29-2013, 09:38 PM Join Date: Feb 2011 Location: People’s Republic of New Jersey.

I’ve heard that you can get a loud whine if the transmission filter is old and clogged as well so hopefully that’s all it is. Is the noise with the TC selector in N and the drive selector in D normal, or does that signify trouble??   #4   07-29-2013, 10:05 PM Join Date: Feb 2011 Location: People’s Republic of New Jersey.

Whining Noise When Decelerating; Causes and Fixing. –

Whining Noise When Decelerating; Causes and Fixing. -If you have ever noticed a whining sound coming from your car when you slow down, it could be that your vehicle has a mechanical problem. However, there are also some other possible explanations for the noise, so it is essential to diagnose the cause before purchasing any parts or making any repairs.There are several reasons for the whining sound in your car, such as the vehicle is not maintained correctly. Therefore, avoid unnecessary modifications like repainting the car, cutting and removing parts, etc. Also, the engine or the transmission may have a problem too. So it becomes hard to determine the actual cause of the noise without the help of professionals. Thus, you should immediately take your car to the mechanic to diagnose and repair work properly. They will do it perfectly and in less time, relieving you from the irritating whining noise.Table of ContentsWhy Does My Car Make A Whining Noise When I Slow Down?Can Low Transmission Fluid Cause Whining Noise? When | Take My Foot Off The Accelerator, It Makes A Noise?Why Is My Car Making A Humming Whining Noise?Why Does My Car Make A Whining Noise When I Slow Down?There are several reasons to explain the whining sound in your car decelerating, such as it may be because of a failing water pump or your vehicle may have a problem in the engine or the driving shaft. Identifying Ring and Pinion Gear Noise – DecelerationThere are many reasons for the whining noise in your car that you should beware of. Here are several ways to detect the sound and also how to fix it:Noise From The Water PumpThe sound is generated when your car decelerates, primarily because of the water pump. The water pump is responsible for transferring coolant to the core. Because of improper lubrication or overheating, you may get this problem in your vehicle. It could be a faulty water pump if you feel a hot, burning smell. You can change the old one with a good quality original spare part to solve this problem correctly.Not Enough PowerIf you feel that your vehicle is performing very slowly, you may be having a problem with the spark plugs as they are not igniting correctly. In this case, you can solve this problem by cleaning the spark plug. Also, make sure that it is free from oil, carbon, and other deposits. If this does not work, get a good quality spark plug of original parts to test and check if it works.This problem can also be due to bad fuel injection or timing chain tension, weak crankshaft position sensor, or faulty injector. This problem can be solved by cleaning the injection pipe or replacing them. This will also help you to fix other issues related to fuel injection.Bad Fuel PumpIf you face this problem, you should exchange the old one with a good quality original spare part from the local auto parts store. A bad timing chain is responsible for having uneven frequency and condition of the engine vibrations in your car. The condition can be bad due to wear and tear on the chains, but it may also result from a loose timing belt.Can Low Transmission Fluid Cause Whining Noise?Yes, low transmission fluid can cause a whining sound in manual and automatic transmission vehicles. If you are experiencing a whining noise when you start your engine and think it is coming from the transmission area, try pouring some transmission fluid into each gear before starting up again.This may temporarily solve your problem with these noises in and of themselves, but it is not going to fix them permanently, and you should still diagnose what is causing them. To test whether you have noise in your transmission, start the engine and let it warm up. Then shift through all the gears to find one that makes a distinct noise with each shift.Next, shift that gear into first gear and give it some throttle while watching for a roar or whirring sound from under the hood. If you hear either of these, it is likely your problem is with your transmission and not something else. A transmission noise can be caused by many…

whining noise when taking your foot off from accelerator

whining noise when taking your foot off from accelerator Joined Jun 14, 2010 ·101 Posts Discussion Starter · #1 · Aug 3, 2018 (Edited) Hello Saabcentral. As the thread title reads, the old 1990 C900i has just started producing a whining noise when I take my foot off from accelerator, and for just a second when I put my foot back down after it has stopped. I’ve been online trying to find out what it may mean, but as such symptoms returns countless possible causes – from loose alternator belt to worn engine mount to bad hub bearings or differential bearings or bad differential or gearbox etc. – I wonder if anyone here may be able to suggest a cause possibly more specific to our old Saabs. The car – just short of 190K – feels great, just flew through its MOT and still is a pleasure to drive. The whining noise began all of a sudden yesterday while driving down from North Wales to London on the M6/M1. The gearbox is good too and as recently as four months ago was given an oil change – 10w30, as suggested in the manual – which I hope is not somehow connected to this unexplained whining. Any advice would be much appreciated. Thank you. Joined Feb 8, 2004 ·8,923 Posts Sounds like it could be final drive. Joined Feb 12, 2006 ·13,582 Posts Noises can’t be diagnosed without hearing them. What happens at speed in Neutral? Does the clutch change the noise? Joined Jun 14, 2010 ·101 Posts Discussion Starter · #4 · Aug 3, 2018 (Edited) Thanks for the replies. Re final drive, unsure, but am I right to presume that ‘final drive’ is the same as primary drive? About the whining noise, it appears unaffected by the clutch, or speed or gear the car is in. I’m not sure about when in neutral. I was driving at around 60-70 mph for about 180 miles on the motorway, so didn’t try it in neutral. All I can say more about the noise without having any idea of whether it means anything at all, is that it lasts for a few seconds on foot up and no more than one second on foot down. I started the car this morning, revved the engine up to 3000rpm for a small while, put it into gear keeping the clutch disengaged (not rolling) and there was no sign of the noise. Just been looking into this further and read that, when changing the gear oil on these C900s, it is apparently advised to add about half litre of oil into the primary drive. This was not done when changing the oil, so am now somewhat concerned that this omission may be behind the noise and, possibly, has caused some serious damage to occur in the primary drive. Joined Feb 12, 2006 ·13,582 Posts Whatever your noise is, it has nothing to do with the oil in the primary drive. Noises can’t be heard over the internet. We can only work with things like ‘when it happens’ and ‘what it sounds like’; high-pitched, loud, screeching etc. It’s just a guessing game, but the more clues we get…..

noise when leaving foot off accelerator – The VR6 Owners Club

noise when leaving foot off accelerator It was nagging so did some hunting, (copied and pasted)Secondary air injectionThe ECU electrically pulls a small solenoid valveopen, allowing manifold vacuum to go to a bigger valve(the combi-valve), which opens a passage from anelectrical air pump to a passage in the head that goesto the exhaust passages. The ECU also turns the airpump on and it blows fresh air into the exhaust. Thisis in the first 2 minutes or so after a true coldstart. It helps finish burning the rich defaultexhaust mixture that is used before the O2 sensorheats up and the system can go to closed loopmetering. The process of the burn completion alsoheats the catalyst faster, resulting in light-off in ashorter time.Both valves and the pump are under the intake manifoldbehind the radiator. Manifold vacuum comes off a “T”in the line to the fuel pressure regulator (silverdisc on the fuel rail).When the car is started and the coolant temperature isbelow a certain temperature (80C, I think), the ECUtests the system by turning it on for a couple ofseconds. This also happens right after the O2 sensorcomes on line after a cold start. Since the O2 isonline, the ECU expects to see at least a 25% leaner(more oxygen) signal from the O2 (less voltage) whilethe pump is running, because it’s injecting fresh airinto the exhaust.Possibilities, in order of likelihood:1. 50a fuse has corroded and is not longer carryingcurrent. Check relay/fuse block with relay 111.Check your air pump gets 12v when the car’s cold.2. Solenoid valve or combi-valve has failed. Air pumpgets 12v and runs but cannot dump air into exhaustthrough closed valve. If you can hear your air pumprun this might be the case.3. Air pump relay has failed.4. Air pump has failed. From what I hear it makesnasty bearing noises before it does though.

Whining Problem When Letting Off Accelerator.

Whining Problem When Letting Off Accelerator. nyazeus #1 Yes its the official first problem I am having and it may not even be a issue. However I dont like hearing it. 03-Z66 and when driving at speeds greater that 55 and I let off the accelerator a whining noise starts at about 50mph and quits around 42. It may be the tread on the tires but its annoying as hell. Sound like its coming from the left front but thats really hard to tell. Anyone else hearing this on their AV? I can even hear it with the radio on. #2 I hear a slight sound when letting off the accelerator, but it’s usually at low speeds. ?Sounds like it’s coming from the engine area. ?It’s a cross between a whining and a hissing noise. ?It’s really noticeable when going slow and when it’s quiet in the Av. #3 I’ve noticed the same thing. It almost sounds like a vacuum leak. Any ideas? 11H #4 Might be driveline howl under de-celeration… When everything is under full backlash? It happens at different speeds because of the harmonics of the sound… Usually this backlash whine comes from the gearsets… I have no idea without driving it… Just throwing it out there… My ’02 Z-71 has no decelation whine… Except when I get off the gas at 5,500 rpm… Then the Flowmaster kinda whines… 11H #5 11H, is correct as usual. i noticed this same noise as well. i narrowed it down to the rear-end. took the AV in to the dealer. they said it was a normal sound. other AV’s do it. not real sure if that makes it normal. i feel better about it though now that i have it documented. #6 I hear the same whine, at the same MPH. It’s got me a little worried, as my father-in-law’s 2500HD was in the dealer’s shop for almost 3 weeks while they waited for replacement parts for the rear end. Everything was shot, on a truck with around 10-12k miles on it. Mike #7 ApolloZ66-2, this is tough to troubleshoot without hearing the issue in person. Do you think the whine really gets louder, or does it get easier to hear when the Av slows down because the road noise is less? If the whine is intermittent, you can verify its not the accessory components by varying their loads, making sure they are operating to their maximum capacity. An overcharged air conditioning (A/C) system, a power steering system restriction or the incorrect fluid, or a failing generator could be the cause. Then again, internal transfer case components, the torque converter or any number of other parts could be the cause. If you take it in to get checked out, please let us know the outcome! jmg3 #8 I have a similar whine in my rear of my 02 NorthFace 4×4 av. It sounds like i am sitting in some old NY cab and when he lets off the gas, you here this awfull whining. Dealer told me it was normal. Seems like all of my AV problems are normal. The only true fix to noises, buy a big stereo system so you can’t hear them!!! See me website below for my “fix” to whining.

Hello, first post here and I just got my first Tacoma. I have an issue that I’m wanting to get an opinion on possibly without taking the truck to the dealership and making a fuss. My Tacoma seems to make a whining noise that comes from somewhere in the engine bay either at moderate to higher speeds when I let off of the gas pedal just after accelerating. But it also does this even when I have the pedal down at higher speeds. Does anyone know what this could possibly be? automatic trans?………….welcome aboard Cell9000 [OP] Member Joined: Jun 27, 2018 Member: #257635 Messages: 10 Gender: Male First Name: Brandon Nashville, Tennessee Vehicle: 2015 Magnetic Grey Metallic Prerunner Nothing yet, but soon. Trying to think of whining in/near engine bay. First thought was 3rd member in rr end but then that isn’t engine area. Does it seem like a certain gear or does it do it with overdrive on or off or both(if it has that) Maybe the alternator whining but that would throw a charge light if really bad other than the bearings in it going out. Other than that I would have to ask how many miles on truck and maybe one of the 3 belt tensioner pulleys starting to die. Kinda hard to tell without hearing it. All kind of things come to mind. Guess if it isn’t constant then probably not some of those things…only when letting off gas makes me think driveline things. Wheel bearings would be constant sound at whatever speed, not just when letting off gas………..hmmmmmmmmmmmmm????

To answer some of you leave questions, it doesn’t have overdrive. It is 2WD, it’s has just under 82,000 miles on it.
