New Holland TC30 Transmission/Rear Axle -- common sump??

[paintpony]

Hi Folks,
I am a newbie to the forum and farm tractors. I did a search on the forum for my question, but couldn't find the answer. I apologize if this has been answered else where. I am helping a lady by doing some maintenance jobs around her small horse farm.....things are in pretty bad shape. She has a New Holland TC30 tractor, she thinks a 2006 version, but not sure, with the 9X3 gear transmission, and 825 hours on it. There is no owners manual to be found (can't find the PIN/SN to get the correct manual). She has no records for when the last preventive maintenance was done, or what was actually done. So, I am going through and changing all the fluids and filters, and greasing all the fittings. My question is about the transmission/rear axle sump for holding the hydro/transmission fluid. I can find the drain plugs for both the rear axle and the transmission, but find only the fill hole over the rear axle (just behind the seat). Does the TC30, with the 9x3 transmission, have a common sump for the trans/hydro fluid?

Thanks for any help you can give!!

By the way, while working on this tractor, your Forum has been a great source of information.

Common sump with at least 2 if not 3 drain plugs. Power Steering separate using the same oil spec. Front axle (4WD) uses the same spec oil. Drain at the differential AND each final drive. May or may not have separate fills on the final drives dependent on build date. Front axle uses the same UFT/ NH 134 hydraulic oil.

My 2003 TC30 has just two drains and one fill for hydo fluid. It is a 9X3. Change the filter when it starts to squeal when you use the FEL if there is one.

Thank you RickB and tcreeley for the replies. I will change the transmission/rear axle hydro fluid tomorrow, along with the front differential and final reduction gears (it is a 4WD). This TC30 does have a FEL, but, as of yet, no hydraulic squealing -- going to change the filter anyway. g
