I have 134 hrs on my 4110. I took it out of 4wd for the first time in two months today and it started making some transmission noise. It doesn't sound like a gear meshing problem, more like two components rubbing. It is a little louder with more speed. I also found oil leaking from the area of input shaft on the front axle. It may be running down inside the sleeve from the output shaft of the tranny. Oil level looked good though. The oil is spread over the center of the front axle and the back of the right steering cylinder. Attached is a photo of the oil at the axle input shaft. The dealer will be here in three days to pick up the tractor. We are thinking the noise might be becuse the oil was too thick. Although the tractor had been running for 30 minutes, I had only been driving it for 10 - 12 minutes. After another 15 minutes of driving the noise is still there though.
