transmission noise. on 2006 BMW X3

the noise comes when you are driveing at very slow speed or when you are stopping and it is heard even on neutral.My x3 is manual.

check the flex couplings first, these are the rubber plates that connect your drive shaft in different places, they are wearout items and need replaced sooner than your clutch
the flex couplings were allready checked and they seem to be ok
have the tranfer drain and check for debris,
Thanks we will try and let you know.
