Gearbox oil interval

Hi guys, this seems a daft question but can't find it in the book. How often should the gearbox oil in a 197 be changed?
 
I'm fairly sure Renault don't mention it anywhere...

It's definitely worth changing though, I changed mine at around 73k during a major service and it felt much smoother afterwards.
Probably worth doing every 2 years or so if the car is driven relatively hard.

Depends on use? I typically go 40k kms between changes, might consider doing even more with an increase in track days.
