Both use an O-ring type drain plug. Often way overtightened...the O-ring gets damaged and it leaks a bit.
Front takes 8.5 oz of Polaris Demand Drive lube. Transmission/Diff takes 44 oz of Polaris ACL fluid.
So you could take some time to inspect for location of leak. Then if it's the drain plug. Drain the fluid into a clean container. Inspect/replace the O-ring, and then
pour the fluid back into the Diff or Trans/Diff.
