Walter V-Drive almost dry

2000 Tige 21V. Did engine oil and tranny fluid change today. Never did the v-drive before but got hooked up by AGraham(thanks again!) with copy of manual so I figured I better take a look. Good thing as the dipstick was almost dry, and when I siphoned the case, I removed only about 1.5 oz of fluid. No sign of leakage in bilge, and if I'm not mistaken, I think I cracked the paint when I removed the dipstick (which means no one had pulled it before?). I remember an earlier post where someone mentioned that these drives are heavy duty and could run on snot, and they must be right. No questions, just a suggestion to include looking at this when doing maintenance and a KUDOS to Walter v-drive for durability.
