Just an FYI. I had a whine about a month ago. Prior to the whine I made a turn and heard a metal popping sound on my right-front side. I originally thought it was a hub and one of the bearings decided to throw a party just like theyve done once a month. Drove a few miles and noticed a sort of whine. Attributed it at the time to the hub still.
Took it to the chevy dealer they diagnosed it as the left driver hub(I know I heard the sound on the right from inside the cabin). The replaced the left side hub and my ISS for the 3rd time. Picked my car up, and still noticed this sort of "electric, whirling, revving" sort of sound. I would hit the gas(not in park, it didn't do it in park) and it would sound like an electrical engine revving also. I called the dealer and told them and they thought I was nuts. It was so subtle and feint but it was there. I know my car, I drive it every day, you know... Anyway, He asked if I could bring it in in a few days and he would take a drive with me. I said sure.
The next morning(cold, maybe 30 degrees) I am driving to work and I'm irate. Probably have had 8-10K worth of repairs into this car in the last 9 months. Every other week it's in the shop. So yeah.... I'm driving on the highway and finally pinpoint to the fact that it has to be related to the tranny somehow. It also has gotten much louder. Neutral didn't have it at all. Only when I was in gear. Even better I would get the car up to 60 and let off of the gas and coast. I literally would go from 60-30 in the matter of seconds. It was like I was dragging something. Sort of like there was no overdrive in the vehicle. The noise was also loudest when i did this also.
Called the dealer and explained. Still thought I was nuts. Said their guys would have heard something like that, I said well they didn't. They hate me because my POS care is in there every other week getting fixed. (But I'm sure they love GM's warranty)
Took a drive with the guy that night, I explained that it sound like gear differentials/torque converter to me. He listed and said he's not sure if the IMP SS has what he believes the problem to be because it's a front-wheel drive vehicle. But said it most likely sounded like a "final drive."
Well to end an already long story.... ended up being the toque converter and "the final drive" whatever that is. I reminded him about the metal pop and said I hope it didn't break apart through my lines. He said they would look into it.
Ended up getting the entire tranny replaced because the single parts & repair outpriced a new crated one he said. The metal pop I heard did leave metal throughout the system.
Posting this in hope that someone else finds my unfortunate POS car's problem useful in case this isn't your problem. I searched and searched for two days on google and ended up finding better info on a volvo forum that described my problem to a T. Prior to, and even after the metal popping and whining, I had zero issues with the tranny. Shifted perfectly, smooth, not hard at all. Would have never guessed it really. I was leaning towards belts imo prior to research. The single biggest thing I noticed after getting back into the car after it was fixed was -- and I cannot stress this enough -- just how easy it is squeezing the gear lever and moving it from park - > drive/reverse and drive/reverse -> park is. It is 100% different feeling. Effortless. Kind of makes me wonder.
Good luck and please come back with the results.
Edit: wanted to add one thing. Ask me how many times the dealership has washed my car for me after getting it back out of the 50 times I've been to the dealer in 9 months.
