Ford - Taurus :: 1999 - Transmission Making Strange Whine Only When It Is Decelerating
Feb 15, 2012
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.

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.

My tuck has been making a whining noise very similar to this and only when it's below freezing out. At 5 degrees it's even louder. Just noticed it the other day. Sounds like power steering whine. I have the 6.2 super duty.

When you put trans in reverse makes whine noise no reverse. The forward gears are fine. Could this be a solenoid problem?

My wife and I recently moved to Panama and we bought a 4 wheel drive 2007 Nissan Frontera diesel pick-up. Great little truck so far, 27 miles per/gal! However, the 5 speed manual transmission has started making a loud whine or growl under power. Down hill, gas pedal up, no noise. Clutch in, no noise. Gas pedal down, growling .Growl is related to ground speed as it stays the same when I shift gears.

This week was our first nice week of the year. Monday I got in my truck at lunch time turned the a.c. on and it blew ice cold. Today my truck sat in the sun all day and I got in it and turned the a.c. on. I noticed instead of the normal "click" you hear when the clutch engages in the a.c. compressor I got a wine and wimper kind of noise. The system never cooled the air after this happened. Is the compressor shot? Is it safe to drive or is the compressor going to tear itself up and send metal pieces thru the system?

My brother and i had replaced the idler pulley and the tensioner pulley oh his 1999 taurus wagon with a 3.0l and after we changed them we put a new belt on it and after about 10 mins of running it started to runoff the alternator pulley put the old pulleys back on and it runs fine except a noisy squeal so we put the new ones back on again and same problem except after about 35 mins it ran off again is there something we are missing this is getting expensive replacing serpentine belts. Like i said with the old pulleys it runs fine just very noisy new ones runs quiet just blows out serp. belts

Ok I have had this noise going on for about 1 week before transmission went out. I just built the trans and its still there.
I had a mishap years back with front end hub bearings so I replaced with New Timken Bearings. Well that wasn't it but at least I know where I
stand with those. It starts making a noise when slowing down about 3-5 seconds before coming to a stop. I thought maybe the carrier bearing in
driveshaft?
Pinion bearing in rear diff? I need to service the parking brakes on rear so I may pull it down and go through it.

The truck is a 2012 f250 6.2 flex fuel from alberta canada. This isn't the first tranny form out there that I've heard do this. Tranny seems fine shifts all right just a whine while accelerating.

I've got a 2016 250 6.2l and am getting a popping sound coming from the transmission area. the following is what i have figured out so far. the noise is made just before a complete stop, just as the tranny down shifts to 1st and can be felt through the manual floor shifter 100% of the time and heard roughly 90% of the time. sound ranges from not audible to loud and is random in how loud it is. the only way it does not do this is if i come to a stop in neutral or i go slow enough as not to have the tranny shift out of first from my last stop. the only other way is if i do one of those long, slow rolling stops. truck only has 6600 miles on it. i will be taking it in at 7500 for first service and have them look at it ...

I recently noticed that my Golf R was making a strange high pitched whine and it seemed like there was no boost. I took my car to the dealer, and it turns out that part of the CAI broke off (a mounting component) and made its way into the turbo, effectively destroying it.
My dealer was initially intending to cover the turbo under warranty (prior to investigation), but now that it is clear that a failure in the CAI caused the issue, they cannot (obviously) cover it under VW warranty. Unitronic CAI failure led to turbo failure.
The serviced manager did some research prior to getting back with me, and was somewhat puzzled since the Unitronic CAI displayed on their website looked slightly different from mine in that the component that failed was not there. The service manager called Unitronic and learned that the failed component was a known issue (it had apparently failed before), and thus they modified the design - hence the picture of the revised version did not match the older version that was installed on my Golf R. The Unitronic rep offered to replace the CAI - but did not mention anything about the failed turbo (when he spoke to the service manager).
I found the following thread which illustrates that this was a known issue: [URL] .... I just wish I had found out about this before it failed.

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.

Ok, just asking a question for a buddy. He has 78k on the truck and the shocks make a strange noise. When one of us bounces the truck up and down on the bumper (simulating a load) the shocks "click". Now I looked and it looks like the bushing may be wore out, and the actual bolt that goes through the upper shock mount is touching the top and then the bottom, emitting the "clicking" noise. Is this just a normal wore out shock, or perhaps a defect? Just asking because I am not as familiar with suspension systems.

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.

Ok my 2002 337 has 87,600 miles on it and for quite a while now its been making a lot of font end noise, its most noticeable at 25-30 MPH, decelerating or holding a steady speed, it disappears when your accelerating hard, and at high speeds. But the noise is horrible, its like a buffeting
Its been serviced regularly, since the noise I've done, new front brake rotors, new pads, wheel bearings, inner and outer CV boots replaced, CV joint checked. My local mechanic who's done a lot of work for me isn't sure what to think, he said try rotating the tires because it may be tire noice on the road? Im running some generic tires, the brand on the tire says "sunny" but they appear to be a good performance tire, and handle well

One of the many things that impresses me about the 6.7 is how well it lugs...... it'll run right down to near 1,000 rpm in 6th gear and stay there till it absolutely has to shift. Like a diesel should. Well, recently, and now more frequently my truck is making some strange noises when it lugs down. It'll mainly do it if I'm towing light, like my flat trailer empty, or maybe if I have a decent load in the bed. But occasionally it'll do it empty. As soon as it lugs down low to 1,000-1,200 and pulls there for a few seconds you'll hear a couple squeaks, then a kinda chugchugchugchug noise. It immediately quits if you let off or make it shift down. It sounds like a turbo-related noise, but I don't really know. Truck only has 9k miles on it. I just know this is one of those things I'll take it back to the dealer and they'll give me the ol "we can't duplicate the problem here." What it could be?

So for the past few months my car was making a strange noise under my car, it turned out it was the dogbone bolt that stretches to the bottom part of the transmission. Some how it got loose and was literally hitting my transmission. So we tried bolting it back on and won't screw which was kind of scary it had some type of play. Do I have to get a new 02m for a little ass bolt, do I weld it, or is there a subframe piece I can buy to replace the Broken part of the transmission.

My mom was driving to pick me up and she said that all of a sudden about half way here that the car started making a knocking sound and white smoke started coming from hood, the car was also trying to shut itself down while she was trying to pull over. It is a 2000 ford taurus with like 130k. I am so scared that it is the head gasket because my mom, myself and my daughter, and my 16 year old sister all share that car to get around. Is there anything else it could be besides that or is that probably what it is?

After coming down a mountain pass my engine started making a weird sound and then died. I am told that it was because I was in too low a gear for the speed I was going (I was using the triptronic or whatever it is called to stay in a lower gear coming down the pass). I had clean and ample oil and no warning lights came on and there are 98,000 miles on it. Does this cause make sense? I have been reading in other discussions that many cars have crank shaft sensors, do VW cars have this? VW Golf 2005 TDI .....
