Going insane! The check engine came on. Code is p1764 which is the governor sensor. Now from what I read that is actually called the transducer. But most videos for it people were also changing the solenoid. So I order both and changed both. Light was still on. I thought a part was bad so I started over changing 1 at a time. (This is a pain as you have to drain transmission fluid every time) all said and done putting a new solenoid and keeping the original transducer fixed the problem and light went of. I went to Autozone and had them hook up the code reader to check and they said nothing showing. Two weeks later BAM! It is back! Shoot me or help me please. Could something else be killing the solenoid? Could it be the transducer even though that was not the problem the first time and what are the chances two weeks later it is that? It is just a real pain to open the transmission pan and drain it multiple times for trial and error like you could use with other jobs (and its 15 degrees out right now) so any help before I start would be so appreciated guys thanks!
