There's a plug on the bottom of the front differential. On your's I believe it's a T70 torx bit. Otherwise if it's a normal hex hed bolt, it's a 21mm. It should be a bronze/gold color, and will sit right behind the front cross member. Pull the plug (make sure you don't lose the washer) and let it drain. Re-install plug and fill through the dipstick tube. The tube will be on the right (passenger) side of the tranny right behind the bell housing. You cant miss the bright yellow handle.
