So I will start by saying that I have a bad Left Rear speed sensor. I'm waiting for the new one to arrive. The speed sensor issue is intermittent . But I did notice that when it does go out it changes the transmission shift points. Is this normal?View attachment 121629
 
Normal. The pcm can’t control the tranny shift points well without a valid signal from the sensors
