All prior diesels I've driven were that way. Transmission holds gears forever because all the torque is down low. You could accelerate without ever downshifting. VERY nice driving experience. None of the engine revving up and down and up and down like a gas engine. Just steady and strong. Even my old Jeep Liberty CRD was like that. Dip into the throttle and it would put me into the seat without downshifting. Niccceeee!!!!
This Gen 3 EcoDiesel is very different. The trans. shifts all the time just like a gas engine. And the throttle response is absolutely horrible. If you need to move out of the way quickly, you push the throttle, make a ham sandwich, flip through your Facebook feed for a while, check the stock market, take a sip of Pepsi, and then the truck takes off. It's not typical diesel behavior.
The only time the diesel advantage and normalcy that I'm used to is realized with this powertrain is when I'm towing. At steady speed with the cruise control set, the low end torque becomes noticeable as the truck stays in overdrive gears (7th and 8th) almost constantly which a gas engine won't do.
Having said that, I wouldn't go back to a gas V8 in this truck. The EcoDiesel is better suited.
