I currently own a 1992 BMW 325i with 230k miles on it. Ran imaculate untill the radiator blew. To make a long story short, when replacing the radiator i removed the tranny cooler and SOME tranny fluid spilled out. Now the tranny is slipping (even tho i topped off the tank).
Heres my question: Even tho theres a lifetime ATF, what harm could it do with a fresh fluid change/filter?? You guys go on and on about microscopic metal particles floating around that make soooo much of a difference if their not in there.....come on are they really that important??
BTW, please dont give me bull about the car having so many miles....ill restate that there were NO tranny problems before this incident occured.

The problem with this is that the metal particles can fill the gaps in the parts they are wearing. By doing this the trans will still work fine even though something is worn which is good and bad. The good is that your trans still works even though something is worn past its spec, the bad part is that if you were to do a flush with a new filter your trans may slip worse than it did before you did the fluid change and can sometimes cause a trans to start slipping even though it didn't slip before. I have seen this happen first hand at the BMW shop I work at and it is hard to explain to a customer why they need a new trans when it worked when they drove it in.
