I use a sheet rock pail for the engine oil.
When I do the hydro fluid I use a sheet rock pail under the first plug, then I move it to the second plug and use the drain pan pictured elsewhere in this thread under the first plug, then I rotate the pale to the third plug, close the first and put the pan under the second. I use the pail when I unsrew the filters also. I tie a rag around my wrist as I pull the drain plug out, that usually stops the old up the arm trick.
I had really good luck at my 50 hour service, didn't spill a drop anywhere until I went to pour the hydro fluid in from a 5 gallon pail, then it turned into a horror show, I ended up transfering it to a one gallon container and then into the funnel, that made equally as big a mess. But as much mess as I made I know I saved a ton of cash.
