Tony:
My guess would be that your transmission is on its way out. You can change the transmission fluid with a high quality Dextron III fluid, Honda recommends using their brand only but that is not necessary in my opinion. The high pitch whistling may be a leak or unattached in a vacuum line.
Good luck.
