Noise from Transmission

1997 GP SE 3.8L

150,000 km

Noise started back 6 months ago......slowly getting worse.Generally described as a whine or growl that seems to be coming from transmission. Car drives fine, fluids all OK, tranny fluid is still red and clean and level is good. No noise unless moving.....once up to speed it doesn't get louder or faster with increased mph, seems steady......slows to stop with braking. Took it into a shop today and they said that it definately transmission noise, not wheel bearing like I suspected (or hoped).

Any ideas?

Thanks

I have a 00 with 55k and I get the growl noise when in park or neutral. Dealer said a bad bearing somewhere in trans but I can remember which one. The car runs great and the noise doesnt effect anything so I am affraid to have them f with the transmission and cause something worse to happen.

My car is a 00 with 80k and whines loudly in manual 1st and 2nd but doesnt at all in drive. I don't understand it. Mine also has been confirmed and is the tranny

Get used to it boys what bearings are not bad in those 4T65's I'm a tranny mechanic see those piles go down a 50K all the time! oh and get used to busted planets thanks to the sun gears pitting out.

and long and behold pitted gears is where whining noises are generated from.

I took my car to a garage and was told that the noise was from the transmission. I took it to a tranny shop and they said it was a bad wheel bearing.........and it was!! Had the tranny filter and fluid changed while I was there.........and a new bearing (hub) put in. Sounded like it was from tranny but a trained ear detected otherwise.
