The hydro fluid is a little low, certainly will accept more. Its been low before without the whistle so I hope that I haven't waited to long to find the leak.
So more fluid is on the list and I only hope that it will be that easy.
Well I've gotten the bottom degreased and it's almost done dripping so I'll climb under to see if I can find the leak source. Seems to be back toward the front or passenger side of the transmission.

Thanks for the quick response and the incite.
Regards,
Bob
