after you get the right tool for the drain plug.. take out the spare tire, take out the rear rubber plug...get a 3/8 vinel hose..( this is the cool part to make it easy) take your 2 quarts of oil, and put them in a bucket of really!!! hot water for a 1/2 hour...this will make it pour much easyer...put on end of the hose thru the hole in the truck and push it into the fill hole on the rear end...snip off a small section of the pointy thing on the oil canester, and insert this into the other end of the hose lift and pour it end..it also helps if you punch a hole in the bottom of the trans fuild contaner...one more thing..you might want to take off the lower plate of the diff. after you drain it,,you will be suprised what is left in the bottom of the pan.. also get a tube of lsd additive, put this in between bottles.
