i was just wondering about this - i never got a chance to pay any attention to my K5 90' transmission and transfer case.
little by little i go through every detail i can in the truck but i never got around to these.
they're both working fine as far as i know, I'm just wondering if there's any maintenance or preventive treatment to be done on those hard working parts?
except oil and filter changing of course. speaking of oil i was also wondering from where the transfer gets it's oil? from the transmission?
