Out of gear

#1

2000 Ford Contour (automatic)

When I’m driving the car it seems like it does not like to stay in one gear and jumps around. This only happens after the car has warmed up and had been driving for little while. It happens at lower speeds and higher speeds, especially on the interstate. I can be going along fine for awhile and then all of a sudden, it wants to down shift and at times it doesn’t to stay in 4th gear. As I slow down it still wants to downshift. I thought it may be the fuel filter, injectors… but the more I look at it, could it be transmission regulator/sensor???
