Hi all, I was testing out a JGC with ecodiesel today at the dealership and I noticed that when i came to a stop there was an abrupt downshift (jolting). It happened a few times but not at every stop. It reminded me of when one shifts a manual and does not ease the car into the gear but slams the gear in and removes the foot from the clutch too fast. The JGC had 18 miles on it. Is this normal?
