Trick for filling tranny fluid and front diff: Take one of those yellow HEET containers that have the spout on one side. Hold it on its side so the spout side is facing the ground. Cut the opposite side off so you can pour fluid into it. Cut a small keyhole slit out of the threads. Now you can insert the threaded part of the spout into the fill port and it will stay there while you fill the fluid from the large opening you cut in the side. Works like a charm for these fluids as well as other small engines like generators etc.
