Ford Transmission :: Gear Whine During Acceleration More Noticeable Near 50 MPH
Apr 18, 2016
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.

'07 FWD Santa Fe exhibits pretty loud "'gear whine" with light acceleration.
Recent ATF change got loads of nasty gook and metallic sludge out of trans.. but no change in gear whine.
Dumb question, but do 2wd Santy's have a differential that I can drain and refill to quieten this whine down a little?

2003 xle v6 auto... 105,000 approx... Seems to be developing a noise, which I hope is not the transaxle. It is a bit like a "whine" or "growling" sound, can't quite place it. Driving around at slower speeds with windows open, cannot really hear anything.
Up at 50 MPH or more it is noticeable and, unfortunately, seems to be getting louder. Does not seem to vary with speed. Don't think it is some weird wind noise.
I did do the poor man's trans flush about 6 months ago (drain pan, fill + 1 quart, disconnect hose, run a quart out, add quart, repeat until clean comes out) and it has been happy. Also did timing belt/idlers/wp a couple months ago. Did not see a way to change the diff. Seem to be a drain, but no fill, so I left it.
My suspects are - wheel bearing(s), cv/axle, transaxle. oh, tires, I guess.

Our 2003 Odyssey had the transmission rebuilt last month after the original finally failed (215,000 miles). After the rebuild, third gear has a whine. (I don’t recall if it was there before the rebuild – it’s the wife’s ride, she wouldn't have noticed it anyway, and apparently I didn't either). The whine pitch varies with RPM, and is louder if the transmission is under a load. Going up a hill with the accelerator depressed makes the whine louder – taking your foot off the accelerator quiets it. I have a warranty for two years on the rebuild, but before I go back and start asking them about the noise, I was wondering what would cause it? I am worried they didn’t rebuild everything and will just tell me the whine is “nothing to be concerned about.” The transmission shifts smoothly and appears to operate normally other than the whine in third gear under a load.

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

I recently purchased a new 2010 Toyota Corolla LE auto and I really like it. I have about 2000 miles on it now and just recently noticed a faint gear whine coming from the transmission at around 60 mph. You can only hear it when the radio is off and you really listen for it during the acceleration. It only does it when transmission fluid is fully warmed up after driving for about 15 miles. 2010 corolla uses U341E transmission that specifies Toyota WS transmission fluid. I noticed that 2001 - 2005 Supra uses the same transmission but it requires T-IV fluid which has more viscosity than WS. Noticed this faint gear whine on this car or do I need to take it to the dealer? My other car 2003 Toyota Echo uses U340E transmission and it has gear whine as well, except it is more pronounced than in Corolla, so I an trying to figure out if this is normal for this transmission or not.

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 have a 2007 Passat wagon 4 motion V6 and what the problem is I am getting a rough shift between 3-4 gear sometimes, usually on a slow acceleration. I have had the valve body replaced which worked for a couple of months until the problem returned. I then had the transmission replaced which worked a little but the rough shifting is still present at times. The car still has warranty and not even the dealership knows what to do?

Have a 2013 Passat Tdi. It seems that sometimes when i accelerate the car doesn't move it has a flat spot as if the transmission is trying to catch a gear. I know this might sound minor to some folks. However on several occasions I've pulled out into oncoming traffic not expecting it to have a flat spot in the car not moving at all. What's up with this?
On the highway no problem and normal acceleration no problem but if you're going from a stop or pulling away from a intersection seems that happen more so than I would like.

Bought my first Hyundai, a 2013 Accent last Saturday. Love almost everything about the vehicle.
It is equipped with the EcoBoost which I can turn on and off.
Noticing when I accelerate almost every time there is some initial acceleration and then a noticeable power loss. It's much worse when I'm accelerating through a turn.
Honestly it's hard to tell too much of a difference with the EcoBoost and AC off.
Also noticing the car really surges at times with the cruise control on. Obviously if I hit an incline it's going to boost a bit, but sometimes even on very minor inclines or straightaways the RPMS just fluctuate more than they seem to need to.
Wondering if this is normal for this engine and something I need to get used to. Coming from a Honda Civic I didn't experience this consistent power loss / fluctuation.

My wife and I just bought a pre-owned 08 Jeep Grand Cherokee with about 60,000 miles that just started to make a whistle sound on initial acceleration and deceleration when the engine is warm and the transmission is in gear and moving. The sound does not happen with a cold engine, when the transmission is in park, or neutral. A local mechanic checked it for vacuum leaks and didn't find any. He thought it may be a dirty throttle body, so I cleaned that out really well, but the whistle didn't go away (it did make the jeep run a lot smoother!). It's difficult to pinpoint the noise since it only happens when the vehicle is actually moving.

I have a '91 Camry that's my daily 50 mile round trip commute car. It runs well and still has lots of pep at 156,000. There are oil and tranny leaks (tranny leaks around the pan seal) but I check the levels and keep everything topped off. Tranny fluid and filter were changed about 20K miles ago. I am the original owner. Shifting is OK unless I accelerate hard, then it "bumps" into gear. On hard acceleration it is a pretty good bump but if I back off the gas it shifts much better. There are no other symptoms, at lower speeds it shifts fine unless the A/C is on, then I get bumps above the 1-2 shift. What the problem is?

The subject: F150, 2007, 5.4L, FX4 version. It has only 80K miles and was very light used by my sister. It seems to me come with a 4R75E ....
Recently I notice a strange vibration every time tranny downshift from 4 to 3, specially noticeable going uphill. Some times can be feel when tranny shift from 3 to 4th...
A friend in my town comment to us, this is a very common condition here because there are just small streets and avenues so that truck shift very frequently betwen 4 to 3 and then back to 4th...
Sounds like a excessive wear on a bearing thrust ??

When running up through the gears under normal acceleration I can feel almost a double shift in 5th gear. It doesn't occur using tow/haul so I assume it is the TC locking up. Everything else seems fine. Truck has 9k miles, mostly towing. 2016 6.2 ....

I'm bringing the car in for a seat belt recall and I'm having them look/listen for a heavy valve clatter under WOT. I noticed this before and mentioned it to them, but of course they couldn't find anything wrong.
BUt it's a very noticeable clatter in 1st and sometimes second, embarrassing actually. The other morning when my GF started it saw a big blue cloud of smoke and she said it ran really rough. Is there some issue with the right bank or any bank on the engine? THere's no way that this engine should sound like that. I thought maybe it was because I was running 87, but most here said they didn't notice anything, and a "knock" doesn't sound like clatter. I also tried running 91 for a few tanks and nothing changed.
We actually like the car, but the amount of problems has been a little disheartening. I think more that when I go to the dealer I feel like they don't even know how to use a wrench.

Phaeton 3.0 tdi ... For some time i have been noticing that the car has a slight hesitation when changing gear from 1 to 2 and barely noticeable from 2 to 3, but as the car gets warmer the hesitation becomes shorter, I don't know if it really is a hesitation , it mostly feels at light acceleration before the oil gets to operating temperature and feels like it slips for like a half second before engages second gear , but as the car warms up it gets better , the car has about 230.000 km , since i bought it i put 50.000 km and did not change the transmission fluid and i guess that before me no one changed it, VW says that the atf should not be changed and many people say that it could make it worse, what the problem is and should I change the Transmission fluid ?

I'm on the road and I pulled over for a pit stop so I don't have time for a search right now, but I noticed under heavy acceleration a turbo whine so high pitched it almost sounds like metal on metal. Is this normal and I just noticed it, a leak somewhere, or maybe indication of something worse? The truck seems to be running ok otherwise. It's an '02 w/7.3 and 220k miles.

So ever since I got my RC 350 my transmission wind has been particularly noticeable. I got the luxury package btw. Wondering if this is normal or if I should contact the dealer about it.

1998 accord 4 cyl auto, mostly on start up and when coming to a stop at a light it sounds like someone is under the floorpan hitting it with a hammer. maybe 5 or 6 hits. I've looked into the exhaust being loose and hitting but it's tight and has good clearance. could it be a broken motor mount letting the engine rock too much? next, SOMETIMES when the trans shifts down into low gear you get a very noticeable clunk and the car kind of shudders. planning on doing a trans drain and fill today. lastly the instrument cluster is a little strange. tach doesn't work at all, speedo is fine as is the gas guage but the temp is erratic. when the temp is acting up you can thump it with your finger and it will jump around.

I recently noticed a very noticeable whine coming from the engine bay during acceleration. It is especially noticeable when accelerating hard to about 4000 rpm and then letting off the gas completely. The pitch changes with RPMs as it spins down. It literally sounds like a super charger spooling up. The car only has 4000 miles and seems to have been doing it since new.

I will try to film the sound and post it later; but for now I have a 3.5L V6 AWD with 85k on it. i get grunting and groaning on colder mornings and sometimes a med pitched whine, more noticeable at higher speeds in town.
