I changed the oil in mine x3 or 4 times to clear it out tbh you could go the flush route via the gearbox oil cooler but that's another world of pain when the push fit connectors, yes I did say push fit fall apart as you try to remove the lines from the cooler.

The oil will have been circulated in a very short time so drain, refill go for a drive, repeated. I bought a massive drum of ATF for mine at the time.

Yes push fits on the L322 standard BMW fitting I'm tolled I even bought the proper tool to release them but decided against it after all the horror stories I found.
They either break up when you remove them or decide to detach after refitting when your driving
