Won't shift through all the gears...dash lights sometimes don't follow shifting!

What is your question?

I got my truck stuck several weeks ago in a huge off-road mud pitt...ever since, I've had infrequent shifting issues. Some days it's fine and other days it would shift a little rough and the dash lights wouldn't move as I shifted through the gears. It runs just as strong but now it won't shift out of 3rd or 4th gear. The RPMs are so high at 45 miles an hour but it won't shift through the rest of the gears or kick down. I'm really thinking it's somethiing electronic but it's slightly out of my area of expertise. My automatic door locks quit working about this same time. Any ideas? I'd apreciate the the assist !
