My 04 Sedan Auto with about 81k miles just started making this noise. It is 100% stock. No mods whatsoever. In 3rd, 4th, and 5th under about 30-60% throttle I started getting this whining sound. I only hear it around 2-4k rpms. I am worried it's the transmission. Anyone else have this noise?

 

You sure that someone didnt install a SC overnight ?

 

^^^ lol it was meeee!!!

 

yup.. anyone actually have any real ideas on what the noise might be?

 

tell the car "stop whining!"

 

Does anyone on this forum actually have any useful information? I appreciate the attempts at humor but I am looking for some assistance on the problem.

 

Nobody can diagnose a sound over the internetS

If you can explain it better...maybe get a video of it, then we might be able to figure something out.

You're expecting us to have an idea of what a "whine" sounds like to you. it could be the wheels,tires, brakes, axle, hub assembly, transmission, driveshaft, and several other possibilities.

Help us help you.

 

Well if it happens under 30-60% throttle between 2-4k rpms then we can probably rule out wheels, tires, axle, hub.. it's either intake, trans, or one of the accessories like p/s pump, water pump, alternator. I also said it sounds like a supercharger whine. That is a pretty standard sound. Mainly I am looking for someone else who has experianced this on their G and can point me towards what the problem was. I don't need anyone to guess or fill the board with jokes.

 

Does it only happen when the A/C is on? A/C compressor?

 

A/C can be off or on. It makes the same noise either way.

 

I looked around on it tonight. P/S and Transmission fluid are clean and smell ok. Also everything on the intake looks good.

 

Did you get your belts replaced lately. An overtightened drive belt can do that. I was originally thinking A/C belt but if it happens all the time, could be the drive belt. Check the tension by trying to twist it. It should rotate between 45-90 degrees at the longest span if tension is within rage.

 

nope.. the only thing I have done recently is replaced the rear struts. the belts have been the way they are for many miles. i checked the tension and it is all good.

 

It could be your Throw Out Bearing.

 

on an Automatic trans?
