How do you know that the trans is what is vibrating? You could have a tire or drive shaft issue. It does appear that your truck is really new I would be getting'ER in for some service! As far will it make it....

You shouldn't be hitting WOT at high revs w/a trailer unless going seriously uphill so I wouldn't worry too much.
Then again, mine's cooked at 12k

RPM related,could be exhaust hitting(not likely).You are the guy I was hoping to answer,sounds like this trans (60,65,70E)do not have a common failure desription like this .Thanks

My 00 truck, I beat the **** out of with a warmed over 6.0 behind the 4L60E w/stall and superior kit.Got 80K miles of towing and maybe 20 WOTs per tank of fuel.

Best advice yet came from a performance shop. He said the 700's can't handle power mods in such a heavy vehicle. He showed me shelves of parts for 4LxE trannys and pointed out many weak points that have both been addressed and neglected over the years as this tranny has evolved...
How did mine fail (in under a week)? - Torque.

Solved vibration.Rather than not saying what I found,I will go ahead and show what an idiot I can be for the sake of this forum and maybe help someone else.I put the truck up on my rack this AM,looking at exhaust,then u-joints which are huge by the way.Then worked my way towards the front,I rotated the front driveshaft and thought,**** this aint right,dropped the truck down then turned the key on .S.O.B It was in auto track.That was what was causing the high RPM vibration.
