How to do a transmission fluid flush (not drain and fill)

07chupacabra · 01-17-2015, 08:09 PM

I've seen various procedures for drain and fills but never one for a flush. How do we do that on our cars, particularly a 2007 Automatic 335i.

It doesn't directly answer your question so I apologize. I drained and filled mine twice over a couple weeks, I figure that got most of it out.

You may have a look at:

IMO not better than drain-fill-drain-fill. Neither ZF is doing flushes.
