Ve ss diff & manual gearbox oil ?

[Johnny1998]

Hi everyone I've got a 2006 ve ss car is supercharged running
750 hp Atw
It's got a 3.9 diff gears
And a tr6060 gearbox

From what I've researched for the gearbox best is penrite progear 70w-75

And for the diff is either
Penrite pro gear 75w-90
Or
Penrite pro gear 80w-140

And I'm pretty sure for all of the oils mentioned the extra additives for the gearbox & diff is already added in the oils is that correct?
& what do you recommend

Penrite GL4 full syn in the trans and GL5 in the diff. Go the 140w in the diff. What diff centre do you have as this will determine what oil you should use? 750rwhp is exceeding what the stock diff can safely handle.

yep i use the 80-140 in my VE diff and also the nulon lsd additive works just fine so far

Full syn with additive, or 140 mineral? What diff you running in that Harrop or standard?

Diff is 3.9 diff gears
Powertrax Trutrac centre

Then you might be better off with GL5 mineral. What does your diff builder suggest?

What's the difference with the GL4 GL5 over the one that just says progear

I thought the 80-140 already comes with additives already
