I've got news for you.  Gear oil used in most transmissions is
only about as thick as motor oil.  Gear oils use a different
scale than motor oils do.  A 75w90 gear oil is close to a 10w40
motor oil, if I recall correctly.  ATF is even thinner and
many BMW manual transmissions call for that.

This is correct.  You just have to make sure you put the
correct stuff in there.  Check your User's manual and here
to figure out what the correct fluid should be.
