I believe that a squeal from the transmission area was written up in an old
QCUSA column by Ned Ritchie. The squeal comes from the rear crankshaft oil
seal. Air is drawn into the engine over the hardened seal causing a squeal or
whistle. If I remember correctly, the diagnosis can be checked by removing
the engine oil dip stick with the engine running and sqealing. Air entering
via the dip stick tube reduces the air flow past the seal, reducing or
eliminating the noise.
Worth a try.
