When getting on it from a stop,or when pulling a trailor the truck shakes like its got bad axle rap, the tranny was rebuilt in house at gm :damnit after going out. Is the this shake from tranny failure?

I am no expert, but it could be they messed up on the rebuild. I'd get it back to the dealer ASAP.

I was sorta of thinking the same thing,Yes it is a long bed and it has 6inchs of lift. SOme one told me that it might be the balancer on the rear yoke of the shaft, but I really don't know.
