My 94 525iT recently started droppping a bit of automatic transmission fluid. It only started recently, but has progressed into a bonafide leak.

I know it's not engine oil, because the consistency and colour is different to engine oil (which I know well!). Plus, it seems to clean off my friveway a lot easier than any oil stains ever have.

My car is fitted with the ZF 5 speed automatic.

There's alot of talk about main seals, oil pan gaskets etc when it comes to leaks, but none seem to discuss automatic trans fluid. Anyone have any idea?
