Shudder or vibration when decelerating?

Hi there. I have a 2011, 4 cyl, auto tacoma access cab, and have had this issue since it was brand new. Every couple of days, when i am slowing down at a stoplight from 20mph to 5 mph, there is a pretty good shudder or vibration from the front end of the truck. It feels like the transmission is getting stuck, and then unstuck. It happens on cold days, hot days, when the truck is warmed up, or just started...there is no pattern. Sometimes it will not occur for weeks, other times it will occur daily. Any other people experiencing this? Any thoughts?
thanks,
jamie

 

Still under warranty?--Since it has been happening since new--INSIST on them correcting whatever you find-FREE.

 

Yeah, I would bring it in and have them look at it if you are still under warranty! welcome man
