On page 129 of the U600 owner's manual it states that the transmission oil needs to be changed at 200hr or 12 months. However, there are no diagrams showing where the drain/fill plugs are located (unlike the engine oil and front/rear gear case, which have diagrams). I've also checked the service manual and it says to use 75w/90 GL5 transmission oil, but again there are no diagrams. I called a dealership and they thought it could be a misprint in the manuals and the U600 doesn't need transmission fluid, unlike the U1000. Anyone else encountered this?
