Ah thanks for the resolution Dmax. I knew I should have topped that off before a trip in which 4wd was going to be seen, but I ran out of time, motivation, and supplies the night before I left. I have no idea what my shifter case is but I'll check next chance (not before I drive home though) based on your description.

Will also need to check on the fluid but Redline 90w-140 would be a good guess.

When I drive through the passes tomorrow I'll really try to give the shifter hell
