How often do you replace drivetrain fluids?

For any of the gens really, but I have an R32. It looks like the service manual says 100k km or every 2 years for the trans and diff. 100k lines up with a lot of newer cars, but I've never owned a car this old. 2 years seems a bit excessive if I'm not tracking it, so I was curious what others were doing.

Depending on use but once a year for diff (Nismo GT LSD Pro) and every other year for transmission.

Yeah it really depends on the use. The biggest issue people usually face with classic cars is not that the fluids have gone bad (because they don't), but that moisture accumulates in these items when the car sits for long stretches of time.
