^ those fluids are fine for a stock setup.
If you are running higher power levels this is what I use
Gearbox: Castrol syntrans
Transfer: Redline heavy shockproof
Diff: Redline heavy shockproof.
Or learn how to rebuild boxes once it makes decent torque
VMX is the stock recommended oil and doesn't have anywhere near the shear strength of the ones I've listed. Of course I'm also making quite a bit more than 500 atw so it might be fine with lower hp numbers.
I just know that I toasted a couple of boxes on VMX and haven't broken a thing on syntrans.
But hey, anyone can use whatever they like as long as it works for them.
