Hey Mike, I have the Kanzaki transmission
as well. And it is a bit confusing about the dip stick. You have the round stick which is a hollow tube with a single
mark very near the end, correct?
Well, that mark is the full line. And the level is checked with the stick inserted but not screwd in. And the oil
is hard to see on the stick.
One way to verify this is to drain the oil and then fill accurately with the recommended amount of oil. Then check without screwing in the stick and you will see the level indicated at the mark.
BTW, it seems this unusual arrangement is because the tubular stick acts as a breather tube for the transmission. In operation the level drops below the stick, and the little hole at the cap end acts as the breather port.
This is how I understand it, others might offer other information and it should be considered as well.
But draining and fill with known correct amount is a good way to check for yourself.
