How do you add transmission fluid to a 1996 caravan

The transmission filler has a level check toward the front. You can't miss it because it says trans fluid on it. Ckeck hot in park. Add fluid using a long funnel you can buy at any auto store. It should be long and have a small opening to fit in the filler tube hole. If its already stinks like a burnt clutch, do not waste your money. OK
