Hi everybody, Total newb here, looking for help. Thanks in advance. My Dana/Spicer 4360 105 5spd is shifting stiff. It was shifting fine when I parked it last fall. Mowed for the first time a couple days ago, now it's super stiff putting in various gears. Disconnected linkage, linkage is fine. Before I pull the transaxle and pull the cases apart I thought I might get on here in case all of you have some sage advice. It's a sealed unit, but is it rebuildable? Again, thanks in advance. Bobbio
