95' Riv making some odd noises

After the car comes to normal operating tempiture there is an intermediate high pitched squeek coming fromth e flywheel/tourqye converter area. There are no noticeable driveablity problems. If you can give me some ideas i'd really appreciate it.

I've had the same problem I think... I'm not sure if it was a squeek or more of a wine... but it went away after I had the transmission rebuilt.
