I have a service manual for the Ford 3500 Industrial tractor but it does not include information for the Torque Converter transmission. The oil in the transmission is a milky color which indicates water has contaminated the oil. The oil passes from the filter and through the radiator for cooling. I had the radiator tested and they found no leaks in the lower radiator tank. The tractor had set outside before I purchased the tractor so I suspect the oil was contaminated from sitting outside. What is the process to drain the oil and replenish the oil? Does the system need to be flushed? If so, how do I flush the system? I've located the oil drain plug on the bottom of the transmission but I have not determined where to add the oil. Any information is appreciated. Thank you.
