Auto or manual?
Manual should get a drain and fill of a good quality synthetic every 30K
miles. BMW uses D4 ATF but a lot of BMW techs recommend a slightly heavier
lubricant. Redline ATF or MTL would be a good choice. Do the Diff and the
BMW recommends an auto drain and fill at 100K. That's too late to do much
good. I think you need to use their particular version of snake oil for the
auto trans ... it's VERY expensive. The Diff and PS should be done at 30K.

Oil filter housing is the larger black-topped cylinder at the front of the
engine. It has a 36mm hex "nut" molded into it and requires a 36mm wrench
or socket to remove. The filter is held in place on the cap and slides
easily off for replacement. Replace the big "O" ring on the cap, the
filter, and screw the cap back on (not much torque, but more than finger
tight ... you'll need a wrench.) The cylinder to its right (looking from
the front to rear of engine) is the PS reservoir ... cap is removed by hand.
Oil drain is on the passenger side of the engine sump pan. Oil fill is that
square cap on the ribbed (ignition) engine cover (has "BMW" in silver and
several silver ribs molded in) it even has an oil can symbol molded into the
cap to keep it simple. The 325 should take 6.9 quarts to reach the fill
mark on the dipstick.
To fill the trans, you need to remove the fill plug (same wrench as the
drain ... 15, 17 mm? Can't remember) on the passenger side of the trans.
Fill until it runs out of the fill hole (about 1.point something quarts)
with synthetic D4 ATF or (better in my opinion) Redline MTL.
The fill point for the transmission (which is what you are referring to
correct?) is a bolt much like the one you loosened when you drained it.
Just up higher on the transmission.
A suggestion - since you have to leave for a trip.. call the BMW
roadside assistance - have the car flat-bedded to your friendly local
dealer, then call a cab to take you where you have to go.
There are some people who should not turn a wrench.
