Dexron VI is the way to go. As for a filter the choice is yours..Hope this helps Tim

GM part no. 12378514.
4.1 pints

Transmission generally takes a bit less than two quarts, Use 75/90 gear lube in that (in very cold climates you can add a small amount of automatic trans fluid to keep it flowing on cold starts) Transfer case takes a bit over one quart and takes dextron mercon 3. When filling either, fluid is full when on a level surface it begins to come out of the fill hole while filling. When changing either, always make sure you can open the fill plug before draining so you know you can replace what you removed.

Automatic Transmission uses MERCON V ATF, 12.7quarts.

Transfer Case uses MERCON ATF, AWD 1.25 quarts, 4 wheel drive 1.4 quarts.

Source Ford owners manual.

if it is an electric shift t-case gm has there own oil not found at auto part stores

Use ATF+4

Do not use Dexron or Mercon

The transfer case shows to use Automatic Transmission Fluid. I would personally use a full synthetic transmission fluid as well. I showed three transfer case options for that vehicle and depending on which one you have it will hold anywhere from 1.5 quarts to just a little over 2 quarts depending on which one you have.
