i had the same question a few months back and i was told that there was no where to fill it, but to my dismay, as i was changing out my alternator, i found a little capped reservoir and when i wiped the dirt and grim

off it, the little bugger said AUTO FLUID ONLY! so then i started thinking...hhhmmmm theres no where to fill? thats weird, so i opened it up and there BY GOD was a dip stick!! MY GOODNESS! then i looked at the little stick and i was low....
