Preheat oven to 325 degrees F (165 degrees C). Grease and flour a 10-inch Bundt pan.
In a large bowl, combine cake mix and pudding mix, then stir in the oil. Beat in the eggs, one at a time, then stir in the lemon-lime soda.
Pour batter into prepared pan. Bake in the preheated oven for 45 to 50 minutes, or until a toothpick inserted into the center of the cake comes out clean. Allow to cool.
