Transmission Noise

[53orbigger]

Looking for advice on whether this is a problem or not. Have a 2001 2500HD with the 4L80E transmission and 180K miles. The transmission had a bearing go out about 2 months ago. I took it into a well known transmission repair shop and they told me it needed a full rebuild. Got the truck back and now it makes a very loud whining sound in first gear that goes away when it shifts into second except when I am towing the boat then I can still hear it in second gear as well. Prior to the rebuild there was no transmission sound at all and now it is so loud people stop and look when I pull away from a stop sign or drive through a parking lot. I took it back to the transmission shop and he did a bit of research and said it could be some housing/adapter/something in the connection to the transfer case and that he would replace it. He did, I guess, and if anything the sound is now worse. I did a bit of digging around on the web and found that it could be the cut of the gears, but he informed me he put the same gears back in and that they were not the type that I was reading about anyway. He is now out of ideas and basically said it must be normal although he is willing to pull it apart and see if he can find anything wrong with it. He also said, not sure if it true, that he called around and others are having the same issue and no one knows what, if anything, is wrong. SO, do I just assume it alright and keep driving it or insist that he find out what is wrong and fix it? Does anyone have any thoughts or experience with this noise? It seems that it is quite common, based on my search, and some people say it is fine and others say the transmission needs to be replaced.

Thanks

Wow that really stinks!...I would not accept that at all...I think the transmission shop needs to figure it out and get it right no matter what!...Just my opinion....Good luck.
