Have a 2013 or 2014. Been having the same old shifting problem, worn out clutch. The other day we were pulling some trees out of the pond with the winch and heard a lout crunch in the rear end. Limped it back to the house and pulled the transmission. I suspected the differential gears were broken, the rear end seemed to be popping every 10" or so of forward travel. The transmission gears looked great, very little wear. Put it back together sorry no pics, and then disassembled the transaxle (pics below) will be sending the clutch of to get it rebuilt and stop the aggravating shifting problems and putting in a gear kit( JD# MIA884078) for the transaxle if I can find one.
