Dropped by the service dept and they had me worried. Please help to confirm

I'm a noob, please confirm with my fluid maintenance schedule

2011, auto, 44000 miles
I haven't replaced anything yet besides the brake fluid, air filter, and normal oil changes

1.Does the automatic transmission fluid ever needs to be replaced? I went to the dealer today and they say that they will find a way to replace it. But my owners manual says 'all vehicles except the Z'

2. When does everyone replace their differential fluid? At 30, 60, 90k or? According to manual, it ALWAYS states to inspect in schedule 1 and 2. Replace only in optional premium service add on.

3. Does the Z have in cabin micro filter to replace? According to the manual, the Z is not listed to have one

4. When to replace drive belts? According to manual, it's ALWAYS inspect in schedule 1 and 2. Replace only in optional premium service add on.


Thanks for all the positive inputs
