Guys,

I bought a 93 320i Automatic Trans. (already in 50k miles) and i am having a doubt on changing the Transmission oil. My colleague said that i do not need to change the trans. oil because it is "lifetime" . But how would i know if my car is equipped with this "lifetime" oil ? Please help.

yes, bmw says its "lifetime" but thats been doubted many times. There is more topics about this. You should change it, especially since you are working in the region. might as well get it out of the way.

In the car's manual under the fluid types and volumes you will see " life time ATF ". I beleive regardless if it is or isn't, replace it. What might happen is the new fluid will wash and loosen all particules in the transmission and might block your new trans filter. If this happens, you should replace the filter and fluid again, till the tranny shifts and operates properly.

Pelican Technical Article: BMW Automatic Transmission Fluid Change
I used regular Dextron fluid for the first flush then I used Dextron Syntec.
Some will say that you must replace with BMW fluid. The choice is yours, I replaced my 1 year ago and no problems.
