I said that the engine/powertrain was not refined. Yes, the vibration/shift issues would be related to the transmission, not the engine.
I have noticed oil consumption. Engines have tolerances, and when you stack tolerances, they can allow some engines to burn oil, and some to not burn oil. If you google toyota 5.7 oil burning, you fill find lots of threads with people describing the issue. I am burning right around 1qt per 5000 miles, and according to Toyota, this falls within the factory allowable specs.
I have no problems with my steering wheel vibrating. I do have gas pedal vibrations. As a matter of fact, I kinda like it though, as it helps me feel more connected to the road and in tune with the terrain. Some seem to find the issue annoying though.
I am not trying to start a debate. I am only stating issues that I have personally experienced, and issues that others have experienced from reading other post in various forums.
