These codes are very common on the Explorer transmission. The most likely cause is a broken over drive servo piston. The repair involves removing the transmission disassembling and having the bores for the overdrive and intermediate pistons releeved. What happens is the aluminum bore in the transmission becomes worn and causes the piston to bind which leads to the piston breaking.
