Transfer Case

See Figures 1, 2 and 3

FLUID LEVEL CHECK



The transfer case should be checked in the same manner as the manual transmission. The level should be up to the filler hole. Use the same viscosity oil as in the transmission. The filler hole is on the right side. Check the oil level at the top hole. The bottom one is for draining.

DRAIN AND REFILL



All transfer cases are to be serviced at the same time and in the same manner as the manual transmissions.

The transfer case has its own drain plug which should be opened. Do not rely on the transmission drain plug to completely drain the transfer case, even if they are interconnected.

Once the transfer case has been drained, install the drain plug. Remove the fill plug, then fill the transfer case (both the NP-207 and the NP-231 use Dexron®II transmission fluid). Install the fill plug.
