Chevrolet - Lumina :: Loud / Buzzy Whine That Changes Pitch With Engine RPM / Transmission Speed
Nov 8, 2012
I have a '99 Chevy Lumina 3100 V6 with 54k miles. There is a loud, high-pitch buzzy whine that changes pitch with engine RPM/transmission speed. The whining noise is only evident while the car is accelerating (forward or reverse), and above 5 mph. I removed the serpentine belt and drove it briefly (500 feet) - the noise is still there without the belt. I figure it's safe to assume it's not the power steering pump, alternator, H20 pump, idler or belt tensioner. The transmission has had regular service, and shifts smoothly in all gears (fluid is clean and level is full). There is only a slight raspy "scraping" noise in park or neutral, which becomes almost undetectable when shifting to drive or reverse with the brake still applied.

I replaced the timing belt an waterpump at 262,000 miles and ever since the engine makes a loud low pitch noise that varies in pitch depending on the engine speed. I replaced the alternator and it didn't work. I don't know if the power steering pump, a/c compressor or something else is making this awful sound.

I have a 99 tahoe 4x4. It has 220000 miles. I had a wheel hum that got loud when I went faster and the pitch changed with speed. It doesn't seem to matter if I swerve left or right. I took it to a dealer and was told I needed bearings, both wheels. I bought the wheel hub assembly and changed them out. I figured it is just better to change the whole assembly. Well, I still have the hum and it seems to be getting worse. I don't know if the u-joint would do that or if it could be a shaft thing. I can not tell what needs to be fixed but can usually fix them when I know what it is. I don't know if there is a transfer case problem either? I know the shaft spins when I turn the wheel. I assume the lock for 4x4 would be in the transfer case? It seems to be getting worse and I don't want to do any damage. I don't get paid for another week and have to drive 50 miles a day.

Recently had my 105K maintenance done which was water pump and timing belt plus whatever other misc belts go with that. Had it done at an indepentdent shop. Since the job was done we have noticed a high pitched whine that increases in pitch with RPM or speed that we drive (literally sounds like a jet engine whine). I took it back to the independent shop and he suggested it was our transmission. I have noticed no difficulty when changing gears nor any engine warning lights. I contacted Honda and our vehicle was part of a transmission recall in 05 that was done already. Other sources have suggested that the whine could be the belt being too tight or the water pump. Shop supposedly used all honda parts. Should I take it back to him again and suggest that the belt is too tight? Take it to the dealer and see what they think?

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.

'98 Chevy Lumina. Driving at Highway speed, I hear a short rattle. Makes me think of linkages vibrating, from the passenger area. Few minutes later I hear it again. Few minutes later I look down to see me thermostat at 240+. I watch it redline, hold for a few minutes, then the rattle again and my temp goes down to 160 or so. All of this happens at 60 mph, in 45 degree weather.
Rinse, repeat about every 10-15 minutes. I notice that while the engine temp is climbing, I have no hot air from the vents and after the rattle and temp drop I do have hot air. Check the block when I get home and I see the familiar green puddles. So is this: Water pump, the apparent source of the leaks, heater core causing back pressure to leak at the hose, or the ever dreaded head gasket?

I bought the car( like six months ago) there has always been a loud humming noise from the fuel pump ( I'm pretty sure it is the fuel pump anyways) not the normal whirring noise the fuel pump makes but a hum you can hear about ten feet away. Had no issues till just lately when the afternoons are well into a hundred degrees. That is when my car starts giving me issues. After one of these hot days on my ride home from work, I had just come off the highway and stopped at a stop light when I felt the engine bogging out, the engine stalled and I had to push it to the side of the road.
Its worth mentioning that this humming noise is much louder in the heat than the cool morning then when I turned the key to hear the fuel pump(auto fuel inject) it was louder than it has ever been, and would keep stalling on the way home, I had at the most a quarter tank of gas (gas boy is busted/stuck I think) the fuel pump is bad? Could it be the sock? I thought I read somewhere that my girl pump uses gas to cool down, and that having the tank any less than a quarter could lead to the fuel pump overheating????

My 2.2 crtd is the first ever diesel car i have bought, but i have noticed a whine especially when cold, pitch bieng raised as engine revs. Is this a characteristic of this car or am i in for a bill further down the line.

Our 2008 Honda CR-V w/120k one owner, always dealer maintained, vehicle has recently started exhibiting a little high pitch whine coming from the engine area which increases when you rev the gas. I checked the transmission dipstick and the level is just below the bottom hole (owners manual says it should be between the bottom and top hole). Would this make the whine? By adding some fluid should it go away? Is it okay to use a fluid other than Honda's?

I recently had to replace my drive belt on a 97' dodge grand caravan sport 3.3 engine. The belt shredded and this is how i knew i had to replace it. Since i replaced it i notice a whine type of noise that increases in pitch as the engine is accelerated. The other thing I've noticed is that all electrically related operations work better as it is accelerated. For example, the air blows harder, the wipers move faster, and the lights brighten. Now i honestly can't say that it didn't do this before i changed the belt. I wonder if a bearing is going out on a pulley. I have noticed the same behavior on my daughters 98 sable. Also note that i did get all of the pieces of the old belt out from the pulleys and i did spin each of them to make sure the were moving without any resistance.

Well, Car is in the shop to get the trans looked at. Loud whining noise in 1, 2, 3. corresponds with engine speed, not road speed. I think input shaft bearings are shot. Going to get a new clutch and throwout bearing while it's out. 116K miles.

I woke up and drove to a stop sign. When I tried to pull away the transmission raced like crazy, HIGH RPMS! But was barely moving. After about 8-15 mph it would finally catch 2nd gear. I check fluids frequently, and topped it off a few weeks ago, and when I finally got where I was able to stop, I looked and there was no fluid registering. So I put 2 quarts in to fill.... Then started the car and it would not go into any gear completely. I'd just feel a small thump, when I shifted. It will actually drop into gear after a while going straight, but it's stil revving HIGH and it won't completely go into reverse. Weirdest thing, the "Anti-Lock" light came on while all this was happening...

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.

Picked up a 2014 IS 350 F Sport (ultra white with red interior if curious) and have been having a blast with it over the weekend. One thing I noticed yesterday though was some transmission whine when accelerating, I drove it home about 25 miles so the tranny and engine where plenty warm and checked the fluid, and between the two indicators it was touching the bottom dot.
If I remember correctly this should be an accurate reading while the engine and transmission is hot, or am I remembering wrong?

Recently my '92 Chevy Lumina (115,600 miles) has taken to not "firing" after I turn it on. It has a brand-new battery and altenator so there's plenty of current. I usually try to get it running 3 or 4 times and if it won't go, I leave it so as to not wear down the battery. It's as if it's not getting any fuel and yes, I do have gas in the tank. I've had the pressure in the fuel pump checked and it was within normal range although on the low end. I can wait 30 seconds or 6 hours and eventually it will "fire" and run.

My check engine light keeps coming on. I've had a couple of mechanics look at this and they say the code indicates the transmission is going out. the transmissions does not slip or have any signs of going out.

The last time I had my car serviced, the mechanic told me that while it wasn't a pressing issue, my power steering pump was starting to go. Lo and behold, it's that time. I started to notice that while idling I hear a dry, raspy sound coming from the engine. I left the car on, opened the hood, and it's definitely something spun by the belt. I'm 99% sure it's the power steering pump, so I'm going to replace it. Furthermore, do I need to "bleed" the lines? How does one go about doing that, anyhow?

My 98 chevy luminas service engine light came on after I got gas. I put vaseline around the threads to seal it and the light went out for 2 days and then came on again. I bought a new cap and the same thing happened, two days light out than back on. I took the car to Autozone and did a diagnostics test which came back with error message P0341, then took it a mechanic who ran his on diagnostics on it and he says the camshaft sensor needs changed. It is a semi expensive job for an older car and I want to be sure that that is the problem, plus the gas cap thing has me confused.

I've got a 2002 Accord with a 4-cylinder engine with 90,8xx miles. For a while now, its been pretty rough and buzzy (not as glass smooth as it once was). Nothing seems out of the ordinary and everything seems fine otherwise, but just the other day, I stopped at a red light and I couldn't feel the engine. I thought I stalled, but I looked at the gauges to see that it was indeed running, but as smooth as melted butter (It hasn't run like that since the car was new!). After making it back home, the car was back to its old rough and "buzzy" self. So, my question is: Is there anything that I can do to return the engine to its glass-smooth idle? Its been tuned up with new plugs, wires, rotor button, and cap, but (all with oem parts too). I had almost forgotten how nice and refined this car was!

I've got a 2006 Prius - yesterday afternoon my wife and I noticed a high pitched whine coming from the front (maybe right hand side) of the car - we don't hear it until we reach about 50mph. It gets louder as we increase speed and then trails off when you step off the accelerator and can't hear it all below 48-45mph.
We bought the car new and are familiar with the various noises the car makes, but this one is new - never heard it before yesterday.

Ok so a few days ago when I was at an ATM i stopped and revved my engine, i could hear a whining sound like bee/supercharger type. It gets pretty loud when i rev the engine and you could hear it whine down as the rpm drops. Now I put it in Sport mode and on drive and when I hit the gas I could clearly hear the whining noise even in the cabin, specially when I let off the gas and let the Sport mode keep the revs up high.
Pretty sure it has done this since I bought it, but I always have music on so maybe that's why I didn't hear it til now.
