vibration or pump noise?
'13 f-150 3.7 v-6 4-wheel drive, I only hear this noise once a day, when I get to work in the am and make a u-turn and head up a slight incline to park, when I put the trans in park I hear what sound like a small pump running or a vibration. If I rev the engine slightly it goes away. This is the only time I ever hear this noise. Truck has 36k miles. Not a big deal, just curious what it is.

Sounds like it could be the sound described in TSB 14-0134. My truck is doing it on the 2-3, 3-4 and 4-5 shifts before the trans is at operating temp. And does it at temperature on the shifts from park to reverse and drive. It's going into the shop next week to have them check it out.
