I took it in and they reflashed the ecu. It has not done it since but it was intermittent before so I will let you know after a week.

 

Mine does weird stuff every know an then right b4 im about to come to a complete stop, but to me it feels like its the brakes or somthing...

 

I am having a very similar problem with my 2010 4x4 scab 4.6L 3V. What was the TSB number?

 

There is a TSB for the shifting and for the bump when stopping. Apparently that requires a relube of the slip yoke. I found this one...

Does it feel like a rumble strip at about 20 mph when slowing down? Mine does....

 

Thanks for the TSBs but I have a 4.6L 3V with 3.73 LS. I have a one piece drive line. Its a small shudder/tremble about 2-3 seconds after coasting to a complete stop. Its just barely noticeable but of course annoying now that I am aware of it...
