02 4.6is transmission screech

[x5Alpine]

Hi, so today I decided to take a drive up a local twisty in my 02 4.6is. On a straight I punched it and then heard in between gear shifts a high pitched screech. It only does it at the higher RPM's when shifting. Is it my torque converter? BTW, the X has 135,000 miles on the original transmission.

Thanks!!

Does it mean the torque converter is coming apart? why does it screech in the first place?

Thanks!!
