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?

I have a 2014 GC diesel with about 46000 miles on it. Every once in a while, I get a hard downshift (usually from 2 to 1) - especially if either the engine is still cold, or if I had been accelerating it pretty hard and then stopped pretty quickly. It's pretty rare, but I can't say it never happens. There was a software flash a few years ago that made it shift easier, but if you are test driving a Jeep with only 18 miles on it, I think it's probably new enough that it should have that already in it.

Thanks for the reply. I actually test drove (and ended up buying) a different trailhawk with the ecodiesel. It had no jolting! I have 400 miles on it without that jolting from the first test drive.
