I did a search. Got 3 results. None of them really answered question.

I asked about this question at my local dealership along with asking how to actually check the fluid level and they told me something sort of interesting, which I didn't try cause I really wondered if it was accurate or not.

At the dealership, one of the mechanics told me that I could check the level of the transmission fluid in my 528i automatic by running it until it is at normal a operating temperature and then while it is running, go under it and there is a filler plug somewhere under the car on the side of the transmission where I can unbolt that plug (while it's running) and check the level of the fluid that way. From what he said, I would be able to feel the level slightly below where the plug is when the plug is removed. That instruction seemed a bit extreme to me because I fear I'd unplug it like he said and lots of fluid would blow out and then I'd have to bring it to the dealership and have them refill it a special way. Anyone know if his instruction is true? or not?

OP, use Dexron III fluid.

Blueskies10, the proper procedure is below. It is important to note that the designated temperature is, according to Performance BMW is NOT operating temperature, and that you should let the car sit for a while.

The automatic tranmission is not equipped with a dipstick. Checking the ATF level requires that the transmission be at operating temperature during the checking procedure.

Note--
Vehicle must be level through tests

• Drive vehicle to warm up ATF to operating temperature
• Connect BMW diagnostic scan tool DISplus, MoDiC, GT1 or equivalent to determine transmission oil temperature. Fluid temperature must be 30° to 50°C (85°-120°F)
• With engine running, switch on air conditioning to increase engine idle speed
• Apply parking brake
• While applying foot brake firmly move gear shift selector lever through all gear positions, pausing in each gear briefly
• Raise and safely support vehicle, making sure car is stable and well-supported at all times.
• With engine running and selector lever in park, remove filler plug.
• If a small stream of fluid runs out of the filler hole the level is correct.
• If no fluid leaks out when plug is removed, fluid level is too low. Add ATF fluid until it starts to overflow.
• Install filler plug using new sealer ring

Adding fluid isn't rocket science. CN90 has a writeup in which he details a method that makes it fairly painless.
