95 325i auto trans...


i want to change my trans fluid, i need to buy a wrench, i would like to know what size to buy before i spend more time and money with trial and error, as i live pretty far from hardware stores and don't want to go too many times..

if anybody can help me i would appreciate it!

They are 17-mm mate, and diff are 14-mm if you were thinking about doing that aswell.

thanks very much... i can go buy a wrench now. i will keep the diff in mind, not going for it today, but i will have to soon. i am trying to get all of the fluids up to date.
