Transmission Sliping?

Am I driving an automatic or a manual transmission? Here’s the scoop….The other day, my wife and I were looking at some very nice houses in an area. To do drive by browsing one would have to almost coast down the street to be able to stop, look and go. Every thing was fine until when it was time to drive off to get to normal traffic speed (35 on that street) the engine sounded like a manual transmission being revved too high in first gear (a hollow roar sound). I noticed this sound right away. I then turned to ask my wife it she had heard this different sound as I had. Well…just like most times I had to pin point the exact noise to her. Once she heard what I was talking about, she agreed.

Ultimately, I was able to duplicate to high revving sound again soon after. The A/C was on…I turned it off …same problem. 2 wheel drive, 4wheel drive, HI and LOW same problem. It is only happening at the take off in first gear with some minor loss of power. All of this and I don't even drive off road.

The next day it seemed to get worse. The high sound of the engine revved with even more loss of take off power. It just about happens all the time from a stand still. I don’t have a clue what this could be. Can this transmission problem cause damage to other engine components? I have heard some good raves about the Titan / Armada transmissions. I am taking My Armada 6/14/05 to have the window switch’s replaced (about an hour job). Now I will also have them check out my transmission and suspension for creaking (time table?). I deserve a rental since I live just out of the free shuttle service. Does anyone have any idea on what is going on with my transmission?
