After 3 years of owning the car, I figured it was time to change the tranny fluid. I have a 17mm socket which worked well, of course, for the drain plug, but it was too long to fit for the fill hole plug. By chance when I was looking for some other stuff at the local equivalent of Home Depot, I found this long type of 17mm "nut". It did the trick and cost about 2 bucks... Just a tip.

Note that the dimension of the nut is (usually) M10, with a wrench size of 17mm.
