Your oil starts at the transaxle..Oil is sucked out of the transaxle by the charge pump on front of the hydraulic pump then directed to the main hydraulic pump and oil cooler circuit...What's happening or not happening..What does the gauge say on the charge test point?? Should read 85 to 115 lbs..What does the gauge say on the main pump standby pressure?? Should read 2750...

Thank you Roy for the info. the Charge pressure is 0 but the transmission works, great drives perfect. slow digging it don' have enough presure to dig a hoe. I traced it to the charge pump,

Thanks Jonathan I will double check everything, there is no pressure in the charge pump, could it be something in the belly of the transmission keeping the charge pump from building pressure?

There should be a suction screen in the transmission case, behind that elbow fitting that the suction hose is coupled to

Charge pump on a 410D is a simple gear pump on the front of the main pump... disassemble to inspect but they are pretty bullet proof.. Check the large suction hose underneath to see if its crushed...also after the oil leaves the charge pump it goes to the filter canister. Sometimes there is a surge relief in there that gets stuck open and dumps all the charge oil to sump...and it never makes it back to the main pump.
