down shift by itself ?

I use my paddles alot, almost every time I slow down. Last night I went up on the interstate and was driving 50 to 70 mph. It was in C comfort. It was in 7 and went to 3 on its own. I up shifted and got it going. Then it started downshifting multiple times in all different gears. I feel that the down paddle was stuck.
It wasnt flexable like the up paddle. It did the same downshifting when I put it in S and M and C. The up would respond but it would still start downshifting no matter what I did to it. I let it sit all nite. The down paddle feels normal. So I took it out today and drove a few miles, in C with no paddles at all. It went perfect.
I know it could be in the trans control, but Im feeling like it may be the down paddle. When I was shifting, I think it may be stuck down. And then that gives constant or intermittent downs to the control module.
Any one with experience with this.
