Follow the given steps to check the Transmission Fluid level on your BMW 325i:
Allow the car to idle. Raise the hood and find the transmission dipstick. It will be located toward the back of the engine compartment. It may be a different color than the motor oil dipstick. The transmission fluid dipstick may even have a picture or words on it. A telltale sign is that the tube the dipstick fits in is smaller than the motor oil tube.
Grab the top of the dipstick and pull it up and out of its tube. Wipe it off with the old rag. Then, replace the dipstick, making sure you push it all the way down.
Pull the dipstick out. Check to see how far up the fluid reached on the stick. (If you don't see any fluid at all, that means there is none.) If the fluid reaches the "Full" mark, then you don't need to add any. If the transmission fluid reached below the full mark, you need to add enough to bring it up.

BMW transmissions are "lifetime fill" meaning that they don't recommend changing the transmission fluid.
how do you change the trans fluid on a 1997 328i automatic trans
You can use any SAE certified transmission fluid in your 2001 BMW automatic transmission. The automaker recommends that you never overfill the transmission fluid.
The indicator light resembling a gear with an exclamation point in the center on a 1992 BMW 325i typically signifies a problem with the transmission or the vehicle's transmission fluid. It can indicate low transmission fluid levels, a malfunction in the transmission system, or a need for maintenance. It's advisable to check the fluid levels and consult a mechanic if the light remains on, as driving with this warning can lead to serious transmission issues.
There is no dip stick for the transmission. there is a drain / fill plug on the side. Open the plug. if fluid comes out you are good. if not fill until fluid drains out.

I had the same question. The transmission fluid actually goes in the power steering reservoir. Kind of strange, but true. For the type of fluid you want to use, check your bell housing. There should be a sticker on it that says what to use.
There are several things that can cause your transmission malfunction light to come on. The most common cause is low transmission fluid.
I added atf fluid right down the dip stick tube. be sure to add very small amounts at a time and keep checking the fluid level as you go.
if it is an automatic there will be a filler neck in the engine compartment, if it is a standard however, there will be a plug on the side of the transmission that will need to be unscrewed, fill until fluid just trickles out and bolt it back up, the fact that you need to top up the level makes me think there is a leak somewhere (front or end seal, or the case itself, find it, leaks only get worse Uhm.... this answer is completely wrong! Your 2001 BMW 325i has a lifetime fill so the only way to check it is on a lift and this is something I would recommend you have a professional do. If there is something going on with the transmission fluid in that year and make of car it's most likely a leak.
Through dipstick tube is usual method w/ a narrow funnel.
