I do not understand this. I took off the drain plug and nothing came out. No leaks from pan or anything else. Is there another plug inside? I have an adapter to fill which screws in the place where the drain plug threads. But am sure some fluid must come down.

I got it done. I missed the bigger 19 mm bolt in the pan to drain. Drained 3 qts, and to fill inserted a hose in the hole of the smaller Allen key bolt up front and added 3 qts. Thanks
