Gearbox oil/diff specs??

[Grahamo spec c]

I used to know this stuff but have forgotten!

what spec gearbox oil do I need? Also isn’t there oil for the centre diff separate in the box?

what diff oil spec do I need?

power steering? Is that just ATF in them?

Any advice would be great please & thanks.

So I need two litres of the LS75?
one for diff and one for gearbox?

 

[BazGF8]

A 5 litre for box and 1 litre for the rear diff , just double check the weights could be different in on the spec c , either Dave or Ali will know

No just 1 liter for the rear diff

 

[Grahamo spec c]

But is there not a separate chamber in the box that takes 0.8 for the limo diff?
nearly sure I replaced it last time round.

 

[BazGF8]

The rear diff is in the rear of the car separate to the box , front and center diffs are in the box and use the one oil

Thanks lads

75w90 in gearbox and LSD oil for rear diff, as recommended by Ali.

This is what I have in my box https://millersoilsireland.ie/product/crx-75w90-nt/

And for rear diff https://millersoilsireland.ie/product/crx-ls-75w90-nt/

Gearbox, front diff and DCCD share the same fluid, and don't use an LSD oil despite there being a front diff.

I know Robbie had some funny Motul 75w120 or 90w140 at some point.

If you aren't in a panic for it, we are awaiting more stock. It's currently on exclusion from Motul.

We have Exol full synth 75w90 in stock also. I've used Exol in all my own gearboxes and diffs, never had an issue.
