My BIL and I were doing our first fluid change on my 2012 800S LE and got to the rear gearcase as we had already done the Main gearcase and the Transfer case. We drained the fluid and replaced the drain plug. We were adding the ADF (Angle Drive Fluid) but the fluid started coming out of the fill plug at only 16oz and my spec sheet says it takes 26oz. We were working in my garage on a concrete floor.

Is the garage floor that unlevel causing a difference of 10 oz? I checked the floor where the razor was sitting with a four foot level and it is definitely not perfectly level but that still seems like a lot of difference in what the spec calls for. I cannot think of any other reason though.
