Neon :: 2000 Dodge - Loud Humming Noise Coming From Transmission Area Of The Car
Dec 11, 2010
As I accelerate, there is a humming noise that comes from the transmission area of the car. It does not make the noise when I am in idle, nor if i put the transmission in neutral and rev the engine.
When driving slow the noise is very subtle. As I accelerate faster the noise gets louder. The noise becomes the loudest at 60 mph. Above 60 it seems to calm down some. The noise is like a constant, deep humming sound. The noise gets softer as I slow down and then is gone when at idle again. To me it seems related to the speed of the tire or the CV half shafts turning or something rubbing in the transmission as the car goes faster. However the sound doesn't change when the transmission shifts. It stays constant and only gets louder as I go faster and then softer as I slow down.
While driving and turning hard to the left the sounds almost disappears until the car straightens out again. I have replaced the struts on all four wheels and this seems to only have caused the sound to get louder. I have also inspected the CV joints. There doesn't seem to be any cracks or signs of wear to all 4 joints. And I repacked the bearings.
The only other things I can think of is the cv half shafts are actually bad and need to be replaced. Or the motor mounts are not aligned/worn out and need to be replaced. Or the kickdown band and low reverse band on the transmission need to be readjusted. Or the transmission is has a problem (however it doesn't slip when driving).

I would seem that my Neon has started a very small leak seems to be coming from the drive shafts. You may call the differentials. You may also call it a transaxle. I prefer to call them driveshafts and transmissions. I took it to a service place to take a free look at it. I do not have the equipment that they have. They put it on the hoist and when you walk under there it does look like it is coming from one of the driveshafts. They were not Tranny experts and said they could not fix it, but said it would need to be rebuilt or changed. My question is, since they are not tranny experts. Does something like this really need to be rebuilt? Is there not just a seal leaking that can be changed without a rebuild? Why would they make something like that? Just to make you pay more money to get it fixed? I did try some Lucas and then Trans X hoping that would seal it up. Lucas seemed to do nothing. Just put in the Trans X today.

2000 Dodge Neon clacking noise at low rpm after releasing gas pedal. Around the 2000 rpm range letting off the gas produces a clacking noise. I have listened to the engine with a long screwdriver at idle and revving. The noise is not always present in this condition. Although when it has come up it seams to coming from behind the engine. Does not seem to be valves, connecting rod or main bearings etc.... Only at low rpm 1200 thru 2000 rpm WHEN releasing the throttle. Clacking seams to be timed with the crankshaft as it reduces the sound as the engine reduces rpm, not at the speed of the cams. Sounds fine at idle, going through gears and at freeway rpm's.

Happened to go down to garage to get something from pip about 3 hours after charge was complete and noticed loud hum coming from right rear wheel well area.
We had not had any lightning storms, electrical interruptions or anything odd; house is on whole house surge protection, and 240v evse has been working fine.
Hum disappeared when car was booted up in ev for a moment and then turned off. Hasn't come back on in an hour.

My engine light came on last November which was diagnosed as “fan clutch seized”. My automatic transmission’s coolant fan clutch was replaced. Since then and on more than one occasion while returning from skiing in the mountains, I will hear this loud whining sound coming from the transmission area. I only hear it when the car is de-accelerating and I have not been able to replicate it once I am out of the mountains and the outside temperature is warmer. Is this a faulty fan clutch issue?

So I was sitting in my wife's car and hear a clunk while the car was in park sitting in the driveway. She said it had been doing that for a few weeks now. The clunk seems to happen every 4 or so seconds while idling and is coming from the engine compartment somewhere. There is also what seems to a hissing or sucking noise that sounds like it is coming from in the dash somewhere and also happens about every 4 seconds during idle. I really haven't had a chance to look into what the problem(s) may be or if they could be connected. I am really not sure what the clunking at idle could be. I think the hissing noise is a vacuum leak I could probably hunt down when I have a chance.

A loud humming (sounds like a compressor). I can place the car in neutral, the engine revs up, and humming will stop. I have to repeat this action for the first 30-45 minutes from start of drive time.

1999 ford expedition 5.4L ....I have been hearing a loudish (I can hear it in the cab) humming noise coming from the engine bay. I don't hear it when the truck is cold (1 to 5 minutes after starting), seems to get louder at it its peak (the more I drive). When i open the hood, the humming is coming from the intake. I am a pretty handy guy, just at my witts end right now....not sure, but I was thinking brake booster?

I have a 2006 lexus es 330 that just turned over 90,000 miles. My dad and I have done the regular maintenance on it so far but this weekend after a 3 hour drive, I turned the car back on and a loud whirring/humming/whining noise was coming from the engine. It gets slightly louder with acceleration, but I can barely hear it once I've picked up speed (but it's still there.) It still happens when I am in neutral. It sounds like it is coming from the passenger side of the engine. Close to the power steering pump area, but the power steering fluid is full (although it is a very dark/black color and has a slight smell...not sure if this is normal.) I'm not having any trouble or hesitation while steering. The rack is operating smoothly and it is not leaking. I plan on taking it into the shop but wanted to go in educated.

I've only owned my neon for 3 weeks. I have a loud knocking/clunking noise and it feels like the rear is trying to freeze up in reverse it knocks/clunks louder when i brake in reverse. Sometimes it will knock/clunk and feel like something is trying freeze up in normal forward driving (maybe one of twice every few days) but it happens every single time i reverse.
We have already replaced the rear struts as we thought this was the problem.
I'm getting frustrated I need a good car to drive my child to school and I afraid to drive this one but I don't have much of a choice. It has had a lot of recent work by the previous owner (my brother-in-law) including a new clutch, exhaust, tie rods, new brakes all around and brand new tires so i'd like to fix it because it's in great shape and runs well for it age.
Another piece of information that may be relevant is the car sat for roughly a year and half with no use but was regularly started although I don't think they moved it. I'm wondering if it could have something to do with the brakes?
The problem starting roughly 3 days after I bought the car I don't drive much but would like to fix this so we can take it on longer trips as it's the only vehicle we own that fits everyone in it. Our secondary is a 2 seater Toyota pickup for my husband to commute to work in and there's 3 of us so the car being in the condition it's in doesn't work for us.

As I begin to accelerate a humming sound from the front of the car begins. The noise becomes more pronounced the faster I go. No additional noise is made when I brake or turn, nor does it appear to be any noise when I went in reverse. I made a 180 mile trip on Sunday with no problems, although I did travel at closer to 55mph than 65. The car has 170,000 miles on it and has had most of its scheduled maintenance performed.

I have a noise coming from what seems like the front windshield area. It sounds like when you have a balloon full of air and open a small hole and let it out. That loud squealing noise that it makes is basically exactly the same as the noise I am experiencing.
It happens when I'm going 70mph in high winds or over 80mph without high winds. And when it happens it's constant.
I talked to the dealership and they told me it's fine... mostly because it happens randomly and it's hard to replicate unless you go 90 it always happens but they obviously aren't going to test drive my car going 90mph to find the noise.

1987 Buick LeSabre V6 w/automatic transmission. Suddenly getting a fairly loud "knock" from somewhere in the engine area. Only present at low rpm or idle, goes away at higher rpm's. Does not seem to be related to vehicle movement. "May" change some with gear shifting but can not really tell. Oil is full and no "idiot" light warning. Timing belt recently changed. Car seems to run fine, just making noise. Any clues???

2004 Dodge Neon SXT ... Let me say first, I know very, very little about cars. But it all started when I was driving down the road and my car was bucking around 40-45 mph, it stayed that way up until I put some gas in the car the next day and the car started shaking violently when I turned it on. Ever since then my car has been not able to change gears. Reverse works normally however. Now the speedo doesn't work at all and somehow the has gauge will fall or rise depending on whether I'm stopping or going.
So I ran to AutoZone and got a diagnostic ran on my car. It gave me codes P0700, P0731, and P0720. I kept calling around and got horrific quotes around a thousand bucks and mechanics saying my transmission was out. However, I turned it over to a close friend who could work on it for free and has some mechanic experience. The first thing we did was replaced both the output and input speed sensors, which didn't fix it. Then I got a new transmission control module, which for my car I assume it is the TCM and solenoid. Still. That didn't fix the problem. Those were some common fixes I found online for neons. But what else it could be.

This time it's about my tranny. After putting on 034 motorsport track density mounts, this whining noise started coming apparent and it's pretty loud and it's coming from the tranny area. Not sure of the fact that the mounts are so stiff has anything to do with it, but here goes...
It's like a slight grinding/mechanical whine noise that happens only when in gear and under load. It gets louder as the speed/rpm's get higher and happens in every gear. Funny, but sounds like a mechanical supercharger whine that you'd get from a supercharged car. When the car is idling, there is nothing wrong/no noise.
Clutch is not slipping, power feels just like it did before, my clutch pedal doesn't get stuck nor is it hard to push down.
A few initial diagnoses from friends were that there is some sort of shaft play in the tranny or that it may very well be a synchro.

2000, F-150, 35K +original miles. 4.6L V8
Some weeks ago a noise started that sounded like fan blades striking against heavy plastic fan guard. At first I thought it was coming from the transmission/Transfer case area but after a few weeks of listening to I now believe it's coming from behind the dash area, however, I can't find any reason for it be from there.
The noise usually starts around 45 MPH
I checked the heater fan and it appears to be Okay. I don't know of any other fans in that area.

It has gotten colder & my 2003 Dodge Neon SXT (140,000+miles) started having trouble & seems to stall transitioning from park to reverse then into drive. It sometimes seems to shift out of the gear and then will stall/engine revs when gas applied but won't move into drive until warmed. Once the car runs/warms up it seems to be ok. Is this a bigger issue (transmission, spark plugs, etc) than just needing to let car warm up longer?

My Neon tranny has been acting up lately with the cold weather. When I first put it in gear, if I do not keep it at a near idle sometimes the transmission will go into a total neutral mode. You have to just stop, wait a minute or two, and then begin to take off very slowly.
Once I get couple blocks it works fine. The temps have been in the 30's lately. Will get colder. I have been letting it warm up for about 5 mins before I drive it. I think it may work more if I leave it run longer, maybe 10 mins. The fluid level is full.
Could it have something to do with the fluid being cold? If so, would letting it idle for a very long time, 10 - 15 mins solve this problem? What is causing this? What can be done?

I have a 2015 IS250 Base with TRANNY PROBLEMS
After 185 miles on the vehicle, I reported the problem to Lexus and the Tech that test drove with me said I was hearing things. Apparently there was a humming noise coming from the transmission.
The noise became evident and consistent, took it back in again, the Tech says its normal and DI engines make a lot of noise.
After six months and 2700 miles the noise became annoying, Tech said they will look into it and confirmed it is unusual. Test drove about 5 other new 2015, used 2014's and no humming noise present.
Engineers made two trips over a five week period from Cali. They changed the alternator, which at first they thought was the problem, then they started looking at the fuel pump on the engine, then they swapped out a tranny from a loaner and the noise disappeared. They took out the loaner tranny and ordered a new tranny and installed it.
