Vehicle is a 75 series Landcruiser, and i am about to do the diffs and gearbox/transfer case. Im a little weary on what oil to use
Gregory manual says to use;
Gearbox and Transfer Case- SAE 90 GL4 or GL5
Front Diff- SAE 90 Hypoid Gear Oil GL5
Rear Diff- SAE 90 Lim Slip Hypoid Gear Oil GL5
Penrite Website says;
Gearbox/Transfer Case- Transaxle 75
Diffs- Hypoid 80W/90
Now i already have some Lim Slip oil for rear diff so thats ok, its just my local Auto One only has Hypoid 80W/90, no Transaxle 75. What i want to know is can i use the Hypoid 80W/90 for my Gearbox and Transfer Case or should i try get some Transaxle 75 somehow. Is there much of a difference in the two oils? Its just that the bloke at Auto Pro told me it would be fine so i brought 7.5L (2.5L Bottles -No Larger amounts available, Rip Off), but now it makes me wonder if Penrite say to use the other stuff.
Any mechanics out there or 75 Series owners

Dont listen to the bloke at auto pro.
Don't use the 80/90 in the gear box/ trasfercase to oil is to heavy.
You will probably find it very hard to change gear.
Transaxle 75 will be ok.
I use penrite oil found to be very good.
Or castrol

Castrol multitrax for the gear box /transfer case
If you are having trouble cold shifting try a full synthetic oil
some else here might have some info on that.

Yeah i didnt think it was a good idea. They have every oil imaginable for Engines, but no Gear oils. Have to try somewere else see if they have the Transaxle or the Castrol Multitrax. Rather silly, and they only sell the gear oils in 2.5L bottles.

The LandCruiser boxes shift better with the Castrol VMX-M 75-90 than they do with Multitrax.
