Hard upshift?

Anyone else with a V8 encountering a hard shift from 1st to 2nd? More pronounced on auto and more subtle on sport mode... All the other gears shift like butter, this would be mild to moderate acceleration I'd say?

As a separate concern, I noticed it seems like the back end has to engage.. This would be only the first time after park or from reverse to drive, such as something slipping or engaging the first time? Only seem to notice it on auto I believe...

I've had the same problem from day one. The dealer has looked at it twice and says it is normal. I am bringing mine back in again next week since now my overdrive is causing my car to shake.

This was among the many things that my car is currently being examined for. http://www.jeepgarage.org/showthread.php?t=21448

They do not know what causes my vehicle to have such weird drivetrain properties. It has intermittent rough shifts, clunks into gears, sometimes the front wheels engage abruptly, WOT shudder, and chugging sensation under light load on a highway or incline. They have spent two weeks trying to figure this out with no solution.

Yea my 1-2 is probably around 20mph.. 35-40 should be like 2-3 or even 3-4 by then.. ??
