Car Noise Identification

Someone else suggested the torque converter over at automotive forums. I asked my mechanic about that, and he said it wouldn't happen at low speeds and especially in reverse. I hope that's true, cause a new torque converter would be very expensive.

Do you have a ball park idea of how much to get this fixed? I'm assuming that transmission work is not something I could do on my own, right? I have limited experience, but I did replace the LIM gasket this weekend.

Thanks

I took the car to a transmission shop. The gentleman said that he didn't think it was the torque converter. He pressed the brake and accelerator when we were going about 50mph and the noise persisted. He also dropped from D to 3 and the noise continued. He said that there is no bearing on the stator; that it's connected to the torque converter. He also said that a bearing noise would show all the time, not just the very special circumstances that this noise does.

He thought it sounded more like air being pulled through a hole, like the air cleaner box. I'm gonna have to investigate that more.

I took the serpentine belt off or a minute and it still made the noise, so it's not any of the accessories.

I'm not exactly sure what you mean by cold air intake. I have the stock air intake. It is inside the stock air cleaner box which draws air from outside the engine compartment.

I think I have a special noise here. Everyone I show it to looks puzzled... Lucky me.

I just got back from the dealership. They said that it definitely was the exhaust, probably the resonator. I find that hard to believe, but they seemed pretty confident. I just need to find a cheap back end to replace it with to see if this is in fact the issue.

I think that I'm just gonna take off the exhaust behind the CAT and see if that takes the noise away for a test ride. I'm not to concerned if it is just the exhaust. My buddy at the dealership said he'd give me one if they get a wrecked Regal. I just want to confirm that it is in fact the exhaust.

Are there any problems with test driving my car with no exhaust from the CAT back? Other than the horrendous noise it's going to make, of course!
