Possible bearing in one of the drive pulleys. I have changed numerous alternators for this noise. Take the belt off and start the car. If the noise goes away you know it will be pulley related and not transmission related. If noise goes away, spin all pulleys by hand to determine the defective/noisy one
If the noise increases when idling and reving up the engine then you must check on the engine pulley, the belt idler pulley, the water pump , alternator or the a/c. But if the noise increases when you are moving then you must check on the wheel bearings, the drive shafts and the inspection of the mudguards for tyre rubbing. If so you will have to jack up the car and check for faulty bearings, drives or tyres. SInce the noise can be traced to the point of generation , you will have to have a friend also to check on one side for pinpointing the sound and identifying the part. This must be easier to find and you can easily replace/repair/change the part concerned. Hope you try. Good day
normally, the only part of your automatic transmission that will make a whining noise is the pump. it usually whines when iether the fluid is low or more commonly when the transmission oil filter is getting plugged up.
the power steering pump will also make a whining noise too.
turn the wheel all the way to the right and hold steady pressure against the stop. this puts maximum force on the power steering pump and, if the power steering pump is the one making the whine, it will change the sound of it. (usually louder).
if the trans pump is making the whine noise, it should sound different in neutral compared to drive. this test will really only work if it make the noise without the vehicle moving. if it wont do it at idle hold the rpms at 2000 or so.
if you decide the noise is coming from the transmission, and the transmission filter has not been replaced (assuming you installed a used transmission), replace the filter by removing the oil pan.
oh and also, if it is the power steering pump you should be able to make it make the whining noise while the vehicle is stationary. if it wont make noise unless its moving its not the power steering pump.
Well, not sure if the temps have a direct cause for your problem, but you may want to check the CV joints on your axles. If you have ripped a boot, and lost the grease, that could cause a whinning. There are also a few other things it could be as well............any more info?
