Hi guys I have a problem with a D6C 10k dozer,we are traying to get it moving for few months now. It just stoped and will not move.The shaft between T.C and transmision is turning very slow and when i put it in gear it stops.We tried everithing, took out T.C 4 times and sent it to diferent mechanics,they all say it is nothing wrong with it,we took out the pump and rebuilt it. It is sending oil to the T.C. The dozer can be turned on, the hydraulic is workin fine.Can someone help me,the winter is coming and it is in the forest.Sorry for bad spelling,i am from Serbia.
