Vibration in floor board

[4OYOTER]

I have only had my 4th gen for 2 weeks now. Two random times I have noticed a slight vibration/rumble that can be felt in the floorboard. Both times it started on a short bumpy part of the road, going about 45 mph, and continued past the bumpy part of the road, until I let my foot off the throttle then it completely disappears. Any ideas?

You have the transmission "rumble strip" issue. It's when the torque convertor is starting to lock up and slips. Any time it starts it will stop when you let go of the gas or downshift manually to 4th.

Here's one thread on it:
