4t65-hd trans squeak??

[JAY0369]

Ive got a 2005 gp gxp with a 4t65-hd trans. It would squeak when the car was in park or neutral, almost sounded like a belt or bearing, so i brought it in. Turned out the trans was making the noise, so chevy replaced it with a new rebuilt one. Only this one squeaks too!! Same thing...in park or neutral. Its not as loud, but it is noticeable. Chevy said that they'll do something if it gets louder, but its new so theres nothing they can do right now. Its the same trans thats in the impala ss, monte ss, and gp gtp... Do any of yous have the same problem or any idea what the problem might be????

Moved to the transmission section.

It could be the sound of the trans engaging and disengaging when shifting from park the reverse and so on.

I have this same problem in my 05 grand prix and it is really annoying. It has a rotational squeak in park and neutral, and at very low speeds (pulling in and out of my driveway). When completely stopped with my foot on the break it sometimes screaches. Seems to go away with a tranny temp of about 140 degrees. I have taken it to two mechanics and two tranny specialists. No one can figure out the squeak. I have read several posts describing the same noise i am hearing but in different vehicles. No one seems to be able to help any of them either. Can ANYONE help???

Jenifer did you ever get a fix for ur squeak?

2 1/2 years later and mine is still doing it. It make me crazy!! GM techs have no idea what would be causing it.
