Question Bad vibrations

Hi

I have a problem with the driveline .. when I accelerate from 35-60mph the car will vibrate just as strong shaking. to it seems like I lose a lot of power.
transmission is overhauled with new converter, do not understand what this might be.
have removed the drive shaft to check all joints, marked announced that these were a little hard to turn around but not so notably.
tires are new. they are balanced.
this is a E350 power stroke. someone who has knowledge of this problem?
thanks in advance, greetings from Norway

but when the engine speed is higher, with more strain on the drivetrain so it goes away.
wondered if it's converter is bad.
also have some slack in output shaft.
any suggestions? need help

Yes I think it may be an injector.
announced it happens at certain engine rpm
vibration becomes smaller the higher the speed I have on the engine.
To connect a rev counter in tonight to see what the engine speed says

broblem was faulty injector wiring harness, this was not the biggest problem but to get the scan tool was challenging in this country, because we do not lead American Ford
to find someone with expertise is impossible.
then I have ordered new injector wiring harness so when it is trying to fix this weekend in 20 degrees below freezing. cold brrr

Then I changed the wiring harness, the car runs very good no vibrations at all.
It feels like I have 100 hp more.
the job was pretty straightforward to do, but very little space to work.
