1999 Rx300 Drive Train Noise

[smoschet]

I have noticed a whistle/whine when below 40MPH; anyone have a similar experience?

check your transmission fluid, pull the dip stick out and see if it smells burnt. Also check its color on a white cloth, should be deep red, if it is black you are in trouble.

fluid is nice and red. could it be the serpentine belt?

When you hear this whine, try shifting into neutral and see if the whine continues. If it does maybe it's your tires that are generating this noise.
