Murray 465602x8C Peerless 6840-P91 Hydrostatic transmission fluids question

I have removed and drained both the hydrostatic oil and transmission gear oil. I have order hydrostatic oil which requires 39 oz. filled 1 1/4" -2" from the top. Ineed to know how much transmission oil, and is it 80/90 gear oil?
I also am looking for the 5" ruuber tube that fits/plugs the hydrostatic oil port.
Thanx
