Question about 2001 Buick Century
When I start my Buick it makes a very loud whine but will become more quite when I shift into reverse or drive. Its still there but less apparent. The whine will become loud again when I push on the accelerator enough to keep my speed up. Not sure if it is related but the car will also stutter for a couple of seconds when trying to start. I had the battery replaced thinking it might be that. What could be the problem? Ive replaced the serpentine belt and water pump which I was told could be the problem but still stuck with this annoying noise.
The whining sound that you here could be coming from a number of places. It may be a coincidence but I think you may be talking about the transmission's pump. You may want to buy a stethoscope. This tool, if properly and carefully used, will help pin point a mechanical noise. Other possibilities are the power steering pump, tensioner and idler bearing, A/C compressor or A/C clutch, or Alternator. I hope this helps, write back if you have any other questions, good luck.

two things it would be 1 your battery could be bad even if it is not
dead and will start your car it could have a bad cell
the other thing could be the belt is loose and not letting the alternator
spin fast to charge the battery so it slips on the belt but thats what the noise is the belt check the battery at autozone for free
and if thats not it its the belt

SOURCE: loud tapping noise in engine
It sounds like you have a rod problem. If that is the case the engine will need to be taken apart to be fixed. Price varys from shop to shop but they can do a bunch of tests on it and tell you exactly what is wrong with it for about 80 to 100 dollars

I would Look For A Vacuum Leak, Given the Fact that ALL that Work was Done in a SHORT Amount of Time, And The Brakes ARE VACUUM ASSISTED, that when Brakes are applied the ENG. Light Comes on, Seems to Me It all May be related. It does not take Much to Pop A Vacuum line OFF Accidentally

The serpentine belt area is large. Remove belt and spin the IDLER PULLY of the belt TENSIONER. and listen for a bearing noise. A common failure. Hope this helps

it does sound like the transmission has packed it in. you might be able to find a decent used one via a wrecking yard and get a local mechanic to install it.
try to find one out of a car with under 100K miles on it.
