3rd gear whine

[adg44]

I noticed today when I was driving with my top up that in third gear, if I take it past 2k RPM, especially above 3k, when I let off the gas I get a very audible whine. It sounded like an elecctrical whine at first, so I shut off the radio, but it was still there. Put the clutch in and it goes away, same if I shift to 2nd or 4th gear. This is the only gear I have noticed it in.

I'm assuming if it was the rear end, then it should whine in any gear, not just third. Perhaps this is a normal sound? It is pretty loud though.

I did a search and saw someone mention a similar noise in 5th and 6th gear, but nothing about 3rd. The car only has 3k miles on it, so the gear oil shouldn't be bad yet, and I haven't really seen where old gear oil causes a whine.

Thoughts? Luckilly I am still under the powertrain warranty if something does need to be replaced.

I've been doing a lot of reading, and I came accross this thread which is EXACTLY the same problem I am having: Whine on Deacceleration - 2003 Viper SRT-10

There was no resolution in that thread, however.

Maybe you should have your rear end fluid drained and sent in to your lab for evaluation.

You make smarty-pants comments like that now, but I think you'll be glad to see the analyzation report.

If anyone has something worthile and relevant to add to this issue, I would greatly appreciate it. It's just so odd that it only does it in one gear...

Thanks,

don't use third gear

I probably have the most experience with PS Pump failures in an 06 coupe than anybody on this forum, not that I want bragging rights to that. When my first one went it whined in third at 3k rpm and above. Are you sure it is coming from the rear of the car or something you just hear in the cockpit with the top up. If the latter have that pump looked at.

Thoughts of having fluid from my rear end analyzed are making me nauseous.

Hmmm.... I will go drive it again today and double check.

I wonder what would test as worse, your rear end fluid or his from his Viper. hmmm???

I read through this thread: 2003 Power Steering Pump Noise.

I did have the recall done, and I don't know if they used power steering fluid or automatic transmission fluid when they refilled it. The Recall was done in the winter of 2005.

One thing to note is that this is really only noticeable on deceleration in3rd gear. When accelerating you can't hear it as much (although that may just be because of the exhaust).

Doesn't mean its still a good pump because of the recall accomplishment. Mine uses ATF-4, not sure about in the 03. Mopar ATF-4 is red in color, Mopar PS Fluid is clear. That should give you an idea what it is filled with by looking in the reservior. Also on mine the fan motor is fed by the PS pump. Is your temps doing anything funny at all. Assuming that pump feeds your fan on the 03 too, I don't know but would think it does.

My coolant temps are pretty much locked at 200 degrees - I haven't seen it fluctuate much, if at all.

I'm going to go down to the garage now with my flashlight and see if my fluid is red or clear.

Check if this noise is also present in 5th gear too.

It might be either a gear or a bearing ....

As Fast Too said, it might be the powersteering pump

OK, I definitely have power steering fluid in there and not ATF, as it is clear. It was a bit low, so I added some power steering fluid (maybe 200 ml). No change in the noise.
