Hi there. The transmission is in limp mode to only go in 3rd gear. The reverse not working and then all of a sudden it works, but will not accelerate past 20 mph, then either the transmission is slipping or the range selector has failed. Check the range selector sensor and see if the harness is attached. Make sure that there is power to the sensor and that the sensor is not loose or cracked. If you replace the range selector sensor and are still having the same problem, then the transmission is probably slipping or the torque converter has failed. If you need further assistance with your vehicle only going 20 miles per hour, then seek out a professional, such as one from Your Mechanic, to help you.
