The OM says:
Transmission:
API GL-5 Hypoid gear oil
SAE 90 (above 41*F)
SAE 80 (below 41*F)
Front diff:
API GL-5 or GL-6 Hypoid gear oil for LSD
SAE 85w-140
SAE 90
SAE 140
Obviously those single weights are pretty hard to find so I had originally planned on purchasing a gallon of Valvoline 80w-90, which contains the LSD additive and will be enough for the front and rear.
Would the LSD additive in the transmission be an issue? The OM doesn't say otherwise.
