Fluid leak in Allison 3060 transmission

Hi Allison man,
I was working my 1997 Beaver Monterey today and I found a fluid leak coming from the forward end, driver’s side of the transmission above the oil pan. It appears to be coming from the area where a wire bundle plugs into a control module. It is not a huge leak but it has wet the front face of the oil pan plus a modest area on the pavement. It must be a new leak as there is no other drip area on my parking slab.

Will the leak increase? How would I go about repairing the leak? Are there O rings on the electrical Plug? Thanks for the help.
