Default Erratic shifting

My 5.9 cummins 24 valve has been acting strangely during highway driving, it will randomly unlock the tourque converter re-lock numerous times for no apparent reason, it will sometimes shift out of overdrive into drive for no apparent reason, it will also sometimes randomly shut off the cruise control itself, and every once in a while the rpm guage will go nuts jumping all over the place before returning to normal. I already know that my tranny is working properly I was thinking maybe an engine speed sensor or something like that anybody ever run across something like this?
