In a large bowl, combine pumpkin, milk, eggs, sugar, pumpkin pie spice, and salt.
Pour into a 13 x 9-inch baking pan. Sprinkle dry cake mix evenly over pumpkin mixture.
Drizzle evenly with melted butter.
Bake for 50 to 55 minutes, or until golden. Ten or 15 minutes before removing
from oven, sprinkle with pecans and return for final baking. Cool completely.
