Im trying best to describe the sound, its a sqeaking noise that isnt constant but every other second almost like a belt I guess you could say. We disconnected the belt assuming it might be that but it wasnt and its coming from the tranny area. Its a impala with new heads/cam/converter and trans, which all have about 100 or so miles on it. I can only think of one thing and thats the Flywheel since they are notorious for this, but I thought it would knock like a rod knock and not a sqeak, someone said it might be the trans pump going out. I am clueless.

 

I had the same thing when my tranny went out and it ended up being the hydraulic pump.

 

Really? What else did it do?

 

Just how you described it. It kind of whined and had a squeeky noise to it. I had to get a new tranny after that.

 

Well I guess we will have to jerk it out.

 

Did you check to see that the flywheel bolts were tight?
