Transfer Case Fluid Change

[daway]

Hi,
I was looking in the workshop manual and did not see a drain plug for the transfer case and only a filler/check fluid plug. In the book they dont state about draining the fluid out.

Does the x5 2001 3.0 have only a filler/check fluid plug and not a drain plug. My Range Rover has a T-case filler and drain plug.

I can just pump out the old fluid out of the filler/check level plug and add new.

Thanks for any help!
