I did a check underneat my Westfalia  87 to see where the automatic
transmission oil was leaking from. I have noticed a kind of pan where the
dipstick conduit ends. There is some leak coming from the conduit and all
around the pan. I also check my  automatic transmission oil  level while the
motor was running and the level was between the two marks. Could it be only
a matter of gasket or o-ring?

Thank you for your replies.
