Vibration/shudder in pedal and wheel upon deceleration (and it's not the brakes or tires lol)

Hey ladies and gents, loving the truck, just got'er Thursday!! Is there a TSB for something torque converter related (or something along the lines) for a vibration while decelerating quickly? I feel a shudder/vibration while slowing down fairly quickly. I kicked it in neutral and tested and it doesn't seem to do it, is there a reprogram that they have to remedy this? If you slown down really slowly its barely noticable, also trans is perfect all other times. I know the tranny is still learning since there is only 150mi on the truck, I'm not worried about it too much but curious what ya'll think!!

If it's still occurring after 500 miles I would at least mention it to your service department, it could be because everything is new and still needs to be worn in.

Thank you sir, yeah it's nothing horrible but it definitely seems like it's torque converter shutter. I tried it again today in neutral from 60 MPH slowdown and it's nice and smooth when you're in neutral versus if you're in drive so something to do with downshifting with the torque converter I believe
