Hello all, I plan on changing the fluid in the transfer case I have a 87 V20 350 TBI so my question is what case do I have (stock) and what type of fluid and capacity thanks in advance.

You ""should""" have a np 208 aluminum transfer case you'll see 2 large drain plug heads that face the rear of the truck there about an inch across +- pull the top plug then pull the bottom also there will be a magnet up inside bottom drain plug and check that for big debri small metal filing on the magnet are somewhat the norm. Install lower plug and fill through the top plug till it reaches the plug hole and starts to overflow. ATF fluid can't remember the capacity like 2-3 quarts not sure.
