Gearbox oil - Which would you choose right now?

Post by Russ Kellermann » 26 Apr 2016 22:28

Hi chaps,

If you were replacing gearbox oil (50B Box - as in all GU Manuals, incl 4.2D), which gearbox oil would you purchase ? I have the 4.2D, which is well known for reverberation noise at low RPM as a result of harmonic resonance, so i'm not keen on anything with light viscosity,as this would obviously accentuate the noise.

I've been using:
Castrol GL4 80W-90 - Gearbox
Castrol Transmax Dex 3 - Transfer Case
Castrol GL5 EPX 80W-90 - Front Diff
Castrol Syntrax 75W-140 Limited SLip - Rear Diff
'07 Patrol Pickup TD42 N/A,285's KM2,3" Lift,ONCA Bars,Warn High Mount,Alu Canopy, and some other Stuff.

Russ,

I use 75W90 GL4 for the gearbox and transfer case
80W90 GL5 for the front and rear diffs, think I also have used EP90 as well......dont think it makes a differance.

I must say that since I started using 75W90 for the gearbox, my gear shifts have been allot better, specially when its cold in the morning. It is also a full synthetic one, but thats only because its the only one I could find.....they are very scarse

But on the gearbox noise at low rpm and idle there was no change
