Hey all recently had to split a b2400 hsd to replace a leaking tranny seal got it back together owner stated no fluid in it I checked before filling and lipstick completely dry. Book says 12 liters got to 8.5L and was over flowing including dipstick tube. Got it running oil went down in pump at back but dipstick tube still full. 3pth hydraulics don't work either.... any ideas? All lines are hooked up etc etc
