The shaking is the transmission making the engine run rough.
Check the fluid in the transmission. Make sure it's full [check while the engine is running and warmed up].
Also, depending on how old the fluid is, you might need a fluid/filter change.

Does the idle jump like that only when it's in drive or all the time?

Alright, then check the level and all and if it's low, fill it up.
Or, just change the fluid and filter if you don't know the last time it was done.
