Today when i was coming home from work i got to the rural roads and turn my over drive off. After that i had hardly any power. edge comp turned on 5x5 it only reached about 2,600 after about 20 seconds with the pedal to the floor. Turned overdrive on and it had power like normal. So i turned overdrive off again and power was still normal. I read the codes when i got home and got p1764 and p1762. Anyone have any idea what could be wrong?

i have heard that there are some sensors that may cause these codes to pop up, and make the trans act up, but i couldn't find anything on what sensors or how to replace them. Has anyone had to replace these sensor that could tell me what what to replace?
