Oil for big HP engine and uprated transmission

[c20tbo]

Guys,

What's best to use, I'm aware there are plenty oil threads but few on uprated transmissions

Engine wise is Titan Pro S 10/50 the one to use

Oppliger sequential gearbox?

Transfer case oil?

Quaife 7.5 rear diff?

Thick wall quaife front diff?

I would stay on atf dex3 on gearbox and transfer. 75w145LS gl5 on diffs

I would use millers crx nano tech 75/90 in main gearbox and diffs. ATF in transfer box.

Anyone care to tell why 75/90 in box and diffs? Diffs okay its what is there oe, but Ford motorsport recomended 75w140 in diffs. Box i have never understood why absolutt need to fill normal gearoil, when mt75(and allot of other manual boxes) is supose to have atf. So just wondering why pepole recomend what they do? Not saying IT must be wrong, but just curius

Gearbox with synchro's needs oil that allow them to work. Hypoid diff oil is not the right choice for that IMHO.

Getting some good feed back guys and a few different opinions, but remember I need for a sequential box and will my diffs be ok having the ATB unit, I will drop Barra an Email see what he suggests
