When I just changed the gearbox oil, I undid filler plug first to check if my pump pipe fits
filler hole. A lots of oil came out, then I drained it from drain plug. I refilled as said in http://www.discovery2.co.uk/Autobox_Oil.html, I repeated twice, then drived 20m, refilled
until 2mm of bead overflowing. I drained 4.5L (maybe including a bit mixed new oil), but filled less than 4L, It means it is short of 0.7L filling. Apparently, if the original gearbox oil was full, refilling can not reach full via filler plug. I just wonder if it affects or damages the gearbox. Any comments? Thanks!
