The computer gave me a P0706 code (transmission range sensor). Also, I'm not sure if this is related to the range sensor or if it's a completely separate issue, but when I get up to around 45 MPH my truck shakes/ vibrates for about 5 seconds. The sound/ feeling when it does this is semi relatable to when you're on the highway and you run over the bumps along the side of the road. However, if I go from 0-60 without letting up (as if I were getting on the highway via the on ramp) the truck doesn't shake or vibrate or anything. It just goes without any issues. Any feedback would be greatly appreciated!
