I used a fancier plan:
1. Drain
2. Break drainplug by over-torquing, run to FLAPS for replacement
3. Fill, get fluid dripping down my wrists and elbows
4. Replace fill plug, clean up spilt fluid, and done!
I think problem is I had a cheap fluid transfer pump with no hook on the end so I had to hold the tube with one hand and work the pump with the other.
