It was my apparent incorrect belief that the transmission and the differential share a common oil sump. I had a problem with the tractor getting stuck in 3rd gear. Removed the shift lever and slid the fork back to correct position, but noticed the dreaded grey of powdered metal and oil on the ball of the shift lever. Made a dipstick and found about two inches of oil. I have the owners manual and the service manual and nowhere does it mention changing the transmission oil. The 13.6 quarts in the diff was due to be changed , so drained it. the level in the trans remained the same. So apparently not connected. Found a trans drain plug and drained out a quart of very different colored 90W. Thankfully with no evidence of metal powder. My experience has always been that the gears throw oil all over the inside of the trans. There is no overflow plug to confirm the correct level. I talked to three service departments that were unable to provide any help. If the two chambers are supposed to be connected with open style ball bearings to provide oil passage, could someone have replaced them with sealed bearings and blocked the passage of oil between the two? It makes no sense that there would be no way to check the oil level in the trans. The oil level on the dipstick behind the shift lever was on the mark, and I measured the oil I drained out and it was the exact 13.6 quarts mentioned in the service manual. With apologies for the long post, I remain puzzled. any help out there???
