    that is an exhaust sheild, nothing to be concerned about really.

    sorry, it would be an exhaust heat sheild, if you want to get really technical.

    Has the problem been fixed? Mine surges sometimes when shifting into 3rd. Almost like the converter is locking and unlocking. A quick stab of the pedal seems to make it go away. (Not jacking the thread) And yes mine will shift hard sometimes when I give it 50% throttle and its wanting to shift. Never stalled yet though....

    Did you check the coolant temp sensor? I had this happen on a blazer it was basically reading -15 degrees when it was more like 120. Spent 14 bucks a poof fixed.

    I'm having the exact same problems as OP from what I can tell. I know I have an exhaust leak if that helps at all, other than that I'm on the same boat . I did purge the fuel from the engine as discribed in the manual and it pretty much eliminated the stalling.
