the vehicle speed sensor is failed on the outside of your transmission, without the signal from this sensor the computer has no clue what speed you are going so it reverts to limp mode, which will allow the vehicle to operate but not efficiently, this will progress,if the vehicle is continued to be driven,and cause additional internal damage to the transmission, it is best to tow your vehicle to the nearest repair facility of your choice.
