HST 5740 plunger leak transmission oil

[malou]

Hi, my tractor 2011 HST 5740 plunger leak transmission oil like 1 pint or more when is oparating or park?
What is the problem?

Where is the leak?
Is it out of the bottom of the clutch housing via the weep drain (pin in a nut)?

If it is it's most likely a propeller shaft seal (FWD driveshaft).

Is this the seal from the shaft that protrudes from the mid-case and couples to the shaft running under the oil pan?
