Re: transfer case oil
My 1972 called for 80/90 gear lube in the 205.
My 1980 called for 30w motor oil in the 205. My 1988 V-30 calls for ATF in the 205. They all work. |

You can pretty much run any 30w motor oil in the 203 full time transfer case. In extreme weather some even run 10/30 in colder climates and 10/40 in warmer areas. |
