1996 K1500 Downshift troubles

    Hi all,

    My 1996 K1500 started having some, what I'm guessing to be, transmission troubles yesterday. It will drive fine if I speed up really really slow. But if I press the pedal down very much to increase the rate of acceleration, the RPM jumps up, then down to below where I was, then back up, then kind of does random weird stuff. If I'm going slow and I press the pedal all the way down, it will kill the engine. I also noticed that the light on the push-button 4x4 had gone out at some point after I had noticed this (should be in 2HI but no indicator light on at all). I press 2HI and it came on and stayed on then.

    I had driven on some pretty rough roads the last couple of days. Does it seem possible that a sensor of some sort may have gotten jiggled out, or does it sound like a pretty serious transmission problem?

    I'm guessing that this is out of my realm of knowledge/experience to fix myself (unless it's a simpler sensor issue), but I was wondering if any of you all with much more knowledge than I have might render a guess of what the issue might be fas I hate taking my vehicles to a mechanic without some knowledge of the problem myself (I still haven't found a mechanic in my area that I feel I can trust).

    Thanks!
