Question about 2000 Chevrolet Blazer

1 Answer when in movement, doesn't whine when parked or neutral

I have a 2000 s10 Blazer, it has a whining under the hood when in movement. I had transmission serviced and it still whines. A road test was done by a transmission specialist with 48 years exp. and it passed. I took off serpentin belt and it still made that whining noise. What is the problem? Do I need a new transmission?

It may not be your trans at all. Look in the wheel wells for any loose plastic panels/mud flaps that may be hitting the tire. Give a slight tug on those panels to see if they are loose. Many times a loose panel will only contact the wheel when there is air moving to push it into the tire.

Whining noise on Volvo 240 when in neural and park

A common cause of a whining or buzzing type noise when not in gear (neutral and park) is a WORN PUMP in the transmission. How many miles are on the car??

A noisy pump is just noisy and won't cause a breakdown until it becomes MUCH louder. If the noise is not that loud at this point, just keep driving it for now, and chalk it up to normal wear & tear. But DOOO make sure your transmission fluid is topped off. The amount of fluid between the LOW and FULL marks is about one pint. DON'T overfill OR allow it to get below the LOW mark. Transmissions are VERY fluid-level-sensitive.

Transmission whining

have you checked the transmissions fluid level, need to check it with the car running in park or neutral, on level ground. If its in neutral make sure the parking brakes are applied and the tires chucked to secure the vehicle and prevent rolling. Locate the dip stick for the transmission pull it out whipe it clean, then re insert it into the dip stick tube until it is fully seated, pull the dip stick out and look at the markings it should read more than half on the hot side.

A whine from under the hood could possibly be a power steering pump. It can whine even when it's full of fluid if the pump is bad. If you're car is a 2010, won't it be covered under the warranty?

Loud whine then knock in overdrive

well, without hearing the noise myself, i could guess that the torque converter clutch might be going bad. the torque converter is the part that transfers the power from the engine to the transmission via viscous fluid motion, the converter also has a clutch that internally provides a direct connection inside the converter for better fuel economy. but as with anything labeled as a clutch, it wears down to a point where is slips. the noise your hear could be the torque converter clutch slipping. i owned a 90 astro van with the same drivetrain that made a noise similar to what you speak of up hills. while driving up hills, fully depress the accelerator and if the clunking noise occurs, then the whine goes away as you accelerate faster in a lower gear, very likely this is the case. you would have to have a transmission shop diagnose further. i drove that old van for five more years cause i didn't want to pay to have transmission repaired. it can be very expensive.

Whining when i press gas

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.

Whine from 2005 corolla automatic transmission

Have the tranny serviced with fluid change and filter, if noise it still there it is the torque converter . Have the dealer fix it ,and have it on paper with dealer invoice when it is done. Do all this before warranty expires. IT IS NOT USUAL for any car, Toyota included, to have tranny whine!!!!!
