Pentastar V6 lack of torque of idle!
My problem is the 2003 rubicon(5-speed) I traded in did the same task without issue. I got the manual thinking the lower first gear ratio(compared to the auto) would be better but I guess I was wrong. I shouldn't have to go to low range to pull out on the highway, stop shift to high range then go.
I was hoping others would chime in with a technical explanation. I am assuming the pentastar off idle has less torque than the old 4.0, I know the pentastar has it beat badly once the rpm gets to 1800-2000 and up. With my old rubicon I could give it a little throttle let the clutch out, the engine would lug down and take off once I gave it a little more throttle. My current rubicon won't do this.
Just as an example, my 99 TJ with the 2.5 would also pull this trailer up this same hill, it required much more use of the clutch than the 4.0 but it would never smoke or stink like this machine does.
I am not attacking the current machine I am looking for a legitimate discussion on this. I am starting to wonder if this type of engine characteristic is why most trucks are not available with a manual. The typical stall speed in the automatic transmissions eliminate the problem. I have never owned an automatic of my own but maybe I should have. BTW the wife's 2013 JGC overland has zero problem with the same load.
