Gear box oil

[daone]

Hi all, I am going to change all drive train oil(front & rear dif, gear box & transfer case)
I remember there was an old posting about we Can use 15w40 engine oil on the gear box. I would like to double check which brand and grade oil will be good please. And what oil for dif and transfer and how many liters do they take please?
Many thanks

My ride is 91 2.8 4JB1T MU two door

Thanks

I use castrol SAF-XA for gearbox and diffs but 15w40 will be fine for the box/transfer. If you have a LSD you will need a oil for the isuzu diff like SAF-XA
Box=2.9 Litres
Transfer=1.4 Litres
F Diff=1.5 Litres
R Diff=1.8 Litres
These are approximate figures
