It is particularly annoying when I was doing a long trip on a two-lane highway recently that kept me at or around the 80km/hr zone. The engine likes being in that 1500rpm range, so it was shuddering a lot.
When I got out on the highway after 6 hours of driving in hot weather and hit a dip in the road where the highway joined a bridge, it revved up super high for a second or so and returned to normal.
I had the Transfer Case oil changed yesterday. I don't have any transmission fault codes (Carly for BMW) and the dealer's technician cleared all my old fault codes out yesterday (including the one for the bad Transfer case oil).
I don't have problems starting and the engine runs great, so probably not a camshaft sensor or Glow Plug.
Is my next stop a deep dive into Torque Converter Potential Problems?

I would, it helped me
