I would take it back to the dealership and ask for a refund. The "technician" who "diagnosed" the problem just diagnosed the symptom of a burned up fuse. Replacing it with a fuse of larger capacity is just asking to burn up the wiring in the car. A burned up wiring harnesses is expensive to replace. The problem has not been fixed.
Any technician who billed for that much labor, and listed the part replaced as only a fuse is not very bright. A blown fuse would have been among the first things to check for in diagnosis, and spending that much time, and then replacing with a fuse of the wrong size is not very encouraging. As an opinion, she is lucky her vehicle did not burn up, or melt the harness, and so is the dealership, as they are on paper as having replaced the fuse...
When the transmission is placed in Park, the MLP switch enables the solenoid that locks the transmission from being shifted unless the brake pedal is depressed. If a fuse were blown, the solenoid wouldn't operate and release the shift lever. There is a manual over-ride on the console for future reference. I would be looking at the solenoid and the MLP[Manual Lever Position] switch and associated wiring.
To know which fuse would surely be good information....
