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.

How to troubleshoot a high pitched whine in the right fron side of my Nissan Maxima 2004


Could be one of the belts slipping or worn out. Might even be the water pump bearing. Does the whine increase/decrease as you rev? Whine louder if you suddenly accelerate?

The right front tire make a whining sound and when the steering wheel is turned to the left it gets louder.


Sounds like you have a bad wheel bearing. Sometimes you can jack up the wheel, in your case the right front) and with one hand spin the wheel while holding onto the front strut spring with the other. If you can feel the noise (sounds wierd but you can feel the noise) than the bearing is bad. It helps if the transmission is in neutral (make sure you secure the vehicle from moving while its in neutral)

Whining noise at low speed


If the noise happens when car is in park and you rev it to about 1500rpm's then its thebearing in the oil pump of the torque converter.It should make noise all the time even in park ideling. You may need a rebuild transmission. Have the vehicle checked out at a transmission repair shop

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.

Adding automatic transmission fluid to Porsche 928 S4


Mine is an 88 cant imagine its different, thereis a plastic tank on the rhs of the trans that has a screw off lid, you will need the car on stands or a hoist level and with the oil at opperating temp you will also need a bottle pump or some type of plunger to fill it the engine must be running and add the fluid slowly allow time for it to be taken into the trans repeat until at the mark and stays there
