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

Do you mean Total Traxium gear 8 75w80 or Total Traxium gear 9 75w90 ?

Finally I used Total Traxium gear 8 75w80. To fill the oil you need to remove clutch position sensor - there are washers between sensor and housing, don't loose them. They are very important to add additional space between sensor and clutch. Without them you'll get an error. There are usually 2x 0.3mm M8 washers. You can put there max 0.8mm spacer but 6mm is better.
