I changed the gear oil last night per the maintenance schedule ( 3000 miles) it was very difficult getting the oil in----the filler hole is sort of horizontally positioned--so I ended up squeezing the plastic cap into the hole, holding a narrow funnell on top, and then pouring in the oil. I had to wait for the oil to go in, then pour a little more--little by little--it took me an hour! There;s got to be an easier way to do this?
