Touareg :: Transmission Whine While Decelerating
Mar 7, 2006
V8 driving from start up in cold conditions (below +15 Deg F) car parked outside overnight, I hear a transmission whine when decelerating. The whining rises and lowers in pitch as the tranny downshifts upon slowing down. It has only started doing this recently.
After the car has warmed up, the noise disappears. However, I find that it is strange that the car would suddenly start doing this, as I have driven that car in years past without the noise. If it had I would put it down to normal warm up noise.

I have a 2002 Accent with a manual transmission with just over 100K. It has for some time had a low whine, which is getting worse. Not wheel bearings. The whine increases with speed, and seems a little louder when decelerating. Makes the sound in every gear and when in neutral (coasting at speed). Brought it into a mechanic and he thought bearings in the transmission (though I don't know why it would make the same sound when in neutral . . .). Shifts through all of the gears fine, no other odd sounds. Can't find any information out there that sounds like my situation.

A co-worker drives a 1999 Ford Taurus with the 3.0L DOHC engine. The transmission makes a strange whine only when it is decelerating. It is quiet and smooth as it accelerates and drives, but let off the gas, and the whining begins. The whine changes pitch and intensity as the car slows down, and eventually fades away once you stop. Stranger still, the whine goes away if you shift to neutral and continue to slow down. It also goes away the instant you begin to accelerate again without stopping.
Someone told him it sounds like a torque converter going bad, but that doesn't seem right to me. The whine starts as soon as you let off the gas, and has a steady decrease in pitch and intensity for speed to stop. It doesn't matter if you slow down easy or quickly. I was thinking a bad bearing in the transmission somewhere in the final drive.

The video below IS NOT my truck, though my truck makes the same sound. Mine isn't nearly as loud as the truck in the video at idle, but gets much louder when under load at about 1700-1900 rpm. If you take it easy accelerating it doesn't get any louder than at idle. At cruising speed in third it isn't audible. The trans in my truck is a 1979 C6. Again, not my video. Same noise though.

I had the front engine mount replaced on my V6 - 3VZ and most of the what I call a clunk has been solved but when traveling at most speeds and taking my foot off the accelerator the transmission seems to clunk and when I reapply acceleration it clunks again. Its like the transmission has to catch up or decrease to the engine speed......my way of describing it!
The mechanic who replaced my front engine mount talked to his friend in the transmission business and they feel it may be a chain in the transmission that is stretched (like a bicycle chain) and the slack causes the clunk. I have never heard of a transmission using a chain, however, I have no clue. Is there a chain? If there is, can it be tightened? If there is not, is there something else that can be tightened? What can I do to eliminate the clunk?
The fluid was changed last year and is red. We are retired and can't afford a transmission rebuild. Everything else is in good shape on this 1992 with 229,000 kms. at this time.

I just put a rebuilt 4r70w in my '97 expedition and it shifts good but in 4th gear when I let off of the accelerator it starts to shudder until it shifts to 3rd. It acts like it is freewheeling then catches on and off. My thoughts so far is that I don't have the digital transmission range sensor positioned right or the overdrive servo isn't working properly.

Have owned a 2014 LS460 since April. Ever since then, when accelerating decelerating between 1000 and 3000 rpm, we hear a whining and grinding noise.

I have a whine that occurs while I am between 70-73mph. The sound goes away when I take my foot off the accelerator. I can sometimes but not easily make it occur at around 40mph as well. The sound is barely noticeable, but definitely there if you listen carefully. What it could be? I have a late 05 model and I have tested without the roof racks.
I also would lke to know if it is normal to hear something similar to a chain turning, this time when you let off the pedal and let the car just cruise. You can only hear it with the windows open especially inside a parking garage. I would think it is normal for the V8 engine or AWD setup, but not sure.

I have noticed a high-pitched whine coming from the front end at high speeds. Above 90-95 mph any use of the accelerator results in a high-pitched noise, unrelated to RPMs. Past 120 it starts sounding pretty bad/loud. My guess is that the fuel pump is sucking so much gas that it is having issues, or the throttle control is just unhappy in that range.

The vehicle is a 2005 Touareg 4.2 v8 with 81k miles. I purchased from a dealership and have been having nothing but problems from the day I purchased it. (2 months ago) the day after I purchased it check engine light came on, headlight range light, air bag light, and now this noise I have owned about 15 vag cars and also own vagcom no codes pertaining to this noise... Above 10-15mph there is an intermittent whine (high pitched) for the most part the noise is there most of the time.
It does not stop when in neutral not effected when the air is off or on, does not change if you down shift, no change if the wheels are turned. I broke down and took it to a very trustworthy Audi shop in the area and you guessed it the entire way there no noise... The tech drove it no noise so I had them flush and fill the trans as it was due for it anyways. They informed me that it was dirty and I figured that it may have taken care of it. Well after a 20 minute drive home the noise started again! I took a short video....

Just installed a Phatbox in my customer's Touareg. With engine running, there is a hum which turns into a whine with engine revving up. VW Service does not have a fix from factory yet. I suspect it needs a filter (capacitor) to suppress RF coming from the ignition system.

All of a sudden after coming back from an Alsp ski trip some sort of loud front drivetrain whine has developed. It's an 05 V8 with 4k miles on it. It's drivetrain because the whine scales with road speed and not engine rpm. It seems to only come from the front too. It starts to get real noticeable around 50mph and increases.
The odd part is I can turn the steering wheel maybe a quarter of a deflection either direction and the sound virtually disappears. I checked out the tires and the tear is good and no usual wear. I am thinking maybe a wheel bearing or a transmission output bearing. I just don't see how anything else could make this whine come out of nowhere so quickly.

This winter when car warms to temperature and with climate control in auto I get fairly loud grinding/whine sound from area behind radio.
If I turn fan off, still get sound; like dampers are moving and rubbing trying to adjust. Set vent buttons to center or top and will stop for a while. Reset to auto and noise starts with or without fan on.
Last trip to dealer they claimed it would not do it; seems like the car has to be warm and outside temperature below 35F. Do the dampers work - vacuum or electrical? Don't remember the problem last winter, this year have had condensate tsb done and also had dealer replace main control module. Wondering if they could have pinch hose or some how caused binding.

I have a 2013 ES350 with 3,000 miles on her. Heard a whine coming from the trany as it shifts? To me, it sounds like a power steering pump whine, but not as loud.

I have a Gen 3 with 145k miles. Never had a single problem with it and it has never needed service other than regular oil changes. Lately I've noticed a whine-like noise that I think is coming from the transmission. I say this because the noise is only present when driving and gets louder the faster the car is moving. It's present with the ICE on or off and does not change with braking (other than getting softer as the car slows down). The noise is steady, not a chirp or some such. Could it be the transmission oil/fluid is way low and needs to be changed? Is there a way to tell the level without draining it?

I have a 2001 GMC Sonoma Highrider Edition it has the 4.3 Vortex and its 4x4 my transmission has been whining slightly it has 169,000 miles on it runs and shifts great it when's when ever its in park and whens threw 1st gear from what I can tell but it doesn't whine in Reverse from what I can tell. This is my first truck and I love it so far and Id hate for the transmission.

My car has 40,000 miles on it and the warranty ends in the near future. I noticed this winter on some occasions a type of whine (not too loud, but noticeable) from the front of the car. The noise and tone seemed to be proportional to the engine revs. I think I recall the noise stopped when I put the car in neutral while it was still moving. I don't notice it now. I would like to avoid any out-of-warranty fixes if possible. Any thoughts as to the cause?

I have a 2007 SE with 3.3L and Auto transmission. 70k miles, regular service performed.
Starting a few months back, I've noticed a low volume hum/whine coming from the engine compartment. I notice it more when I'm in drive, but also notice it to a lesser degree when in park and revving. In drive, the sound gets just a bit louder and higher pitch, until shifts, then lowers at low RPM, growing again as revs move up.
since it happens in park, I'm thinking it is engine related, not transmission? (I usually change oil around 4k, sometimes as high as 5k)...

Bought a 2011 Toyota Camry about 2 weeks ago. Noticed a few days ago a severe whine I think is coming from the transmission, when it is started. The noise goes away after about 2 miles of driving and the car seems to shift OK. The dealership says this is "normal", but I've not heard other Camrys doing this.

Been having loads of fun with my Excursion. I've completely gone through the rear axle, new Yukon 4.30 ring and pinion and "ALL" new Timken bearings. I set the pinion at 30 inch pounds preload. Back lash is 13 thousands. But now I have a gear whine during acceleration. Slight at first but more noticeable near 50mph. Coasting or decel is quite. But just barely touch the gas pedal and it starts to whine.
I know that the backlash spec is published as 6-10 but other sources state 12-15 thousands. So that's why it's set at 13. Gear pattern looked great to me. In fact most changes I tried had little effect. So is it just normal for a gear set to whine until broken in?? Should I reset the backlash down. I only have about 40 miles on it. But would like to fix before it's wrecks something.

I just purchased a 2011 Toyota Camry with about 36,000 miles on it. Within the past couple weeks, the transmission began producing a very loud and uncomfortable whine when accelerating at low rpms. The sound resembles that of a kazoo or a super charger. I've taken the car to several dealers and have been told that it's a "normal" noise for the 2011 Camry. To test the validity of this comment, I asked to test drive a few other 2011 Camry's and only a couple made this same noise. The dealer did replace the power steering pump, as he thought that might be causing the noise. However, the noise is still present and seems to get louder with each day I drive the car. I do not believe this noise is normal.
