Underfilled Trans from the factory?

Hey guys, new member here… I bought two 2015 Sportsman 570’s last July (2015). Changed the engine oils at 20 hours, came out very clean, impressive.

Now that I have 30 hours on both machines, I changed the front diff and transmission fluids today. Again, both were very clean… I probably could’ve went longer. Didnt notice any glitter, no water, axle oil was clean (looked new), the transmission fluid was purple but I drained it into a clear tupperware (shhh dont tell the wife :laugh2:) and didnt notice anything unusual there either. BUT while 1 machine had a full quart in the transmission, the other machine had less than HALF a quart!!! And the drain plug was loose. Loose as in, it didnt take any force to "break" loose the drain plug. The other machine took some muscle.

I have closely monitored every detail of these bikes since I bought them, sans actually checking the level of the transmissions because the dealer gave me a checklist of things they supposedly "checked" and fluid levels was one of them. With 593 miles on the machine, and 30 hours, did I do any damage? No glitter came out and the fluid was still purple. Im a little worried tho.

By the way, both machines seem to shift smoother and quieter now with new fluid!
