Go with Kevin's advice, it is sound and make sure synthetic, as it his higher both temp range and ultimate temp allowed
First number is the lube's viscosity at room temp (how thick/thin in reference to water) and second number when it gets up to working temps
By design...all gearing lube is supposed to have enough viscosity and film strength to coat the gear teeth so that there is no metal to metal contact between gear teeth faces....but poop happens and they occasionally do go metal to metal
Why having the correct viscosity index is so important and again, synthetic. It has higher spec both in film strength & temp range
Stay away form the very good exotic anti-friction lube additives if you have clutches in there (LS, G80, etc)....to slippery and will ruin those clutches
