I was changing the oil on this beast and I notices a sensor/plug with a red seal on the tranny. The sensor is going in the middle of the tranny. It's not the speedo, there's a different plug for that.. Does anyone know what it does??? I unpluged it, and the truck ran the same.. Does it have to do with TM.. Just would like to know, thanks.
