if it makes you feel better i have a penned topic on another forum for newbies about that exact thing !
ok there is no dipstick
the oil is good for 100K so not easy to add it !
how much did he drain out? if less than a cup or so you would be ok going to the dealer
it takes special tranny fluid !!!!!
if more than a little bit..well think you can use a pump and add some fluid through the side hole on the case? just make sure you have the right fluid !
the dealer usually does a system flush to replace the oil ( bout $1 to 2 hundred if i remember?)
to add the right amount they do temp check and run through the gears , so not a easy dipstick thing, but it is a no maintenance item
