Peugeot 508 Hybrid4 oil for rear differential and gearbox

[Doom]

Hello,

Just a quick question, do anyone know what kind of oil should I use as replacement for Peugeot 508 Hybrid 4 for rear differential and gearbox? I heard from local dealership that this is lifetime oil, they don't recommend replacing. As I understand I should wait till gearbox end it's life Every oil degrades. Additionally where can I find screw/hole to fill the oil?

I'll reply myself:

I'll use Total Traxium gear 9 75w80 for rear differential, same for gearbox. For the hydraulic actuator I'll use Ravenol GHA-F
