Here are pictures of the speedometer driven gear for the GTK-134 four speed non-synchronized transmission. The gear and fitting that holds the gear in place and attaches to the speedometer cable come apart as you can see. There is no seal at all. Notice that one of the gear examples has a spiral groove that acts as an oil slinger. I can tell you that the oil slinger is not that effective and after all, some oil would be needed where the shaft goes through the fitting. I have a damaged gear (also pictured) that does not have the spiral groove, so there is some variability in design.

Bottom line: Tranny gear oil will drip from that area.
