Thank you for contacting the AnswerARMY.
I hope you have many good years of service with the machine you have acquired.
It is hard to know if your transmissions are normal or not, not being able to hear them. All Hydro transmission do have some whine or growl to them. The hoses you mention are indeed ventilation and expansion tubes for the transmissions.
You would need to contact HydroGear (the transmission mfg.) for any service information on the transmissions.
