where does the vibration feel like it's coming from and what does it feel like?

It feels like your running over them
Little bumps on the side of the road.
The whole truck shakes.

is it in all shifts or just around 35-45 mph? getting up to highway speed...

some vibrations will go away with a trans service, changing the filter and oil. sometimes it is more. try driving the truck with a scanner looking at the trans data stream. See what the lock up and OD are doing. It could also be a mechanical problem.

you're probably going to need to take it to a trans specialist. they should have a tool they hook up to the trans and control all the shifts and lock up so they can see what affects the condition you have
