Ok so I drove it this weekend and noticed that the vibration is only there when the truck shifts into OVERDRIVE? Once the truck is in overdrive, vibration will be steady until the granny shifts down. Peak vibration is 70mph anything before or after that is mild but it's there.
This is driving me crazy!!!!! Any help is always appreciated.

When it shifts down are you still at same speeds you notice the vibration at? What does it do when coasting down from 70? Is it vibrating just at cruise or under accel in o/d? Could be a prob in o/d unit or rear end, tires, tcase. Id try running in a diff gear at the same speeds you notice the vibration. to rule some things out. Really your tranny shop should be checking all this.

Yes to first question. When coasting down from 70 mph, I will get vibration. Also when coasting down from 70 the truck will keep a higher idle until it drops out of o/d. The vibration is most prominent at cruise and deceleration, upon acceleration I don't notice the vibration. Could be harmonics of the engine disguising the vibration? I'll try running a different gear and see?
