Drivetrain jerk

[HummBebe]

Seriously though, what could it be??? After decellerating, when you begin to accellerate, there is a deep sounding (like when you forget to downshift and try to take off....lugging the engine) clunk/jerk before it will shift down to accellerate.Usually around 2000 RPM's.

I know the "hunting" thing is normal for GM....but again, this didn't start until I had the T-Case/Rear diff serviced.

Also, when I did have the T-case serviced, I went to pick it up, and as I drove down the street, (after hours of course) it would not shift out of first So I had to leave it there and come back the next morning. They fixed
it quickly and sent me on my way.

They forgot to reconnect the "shift soleniod"??? (I can't remember exactly)

Am I making any sense???


I would like to resolve this before I head out to Moab. If it is not a big deal, I can wait.

Thanks in advance for your help.
