Transmission

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!

Around 40 mph is about where the TCC torque-converter-clutch often engages so i wonder if that could be a factor. Your report about how it doesn't happen when you accel quickly to 60 also seems consistent with a TCC involvement.
the OBD code seems to indicate that the gearshift selector signal is out of range. this sure could confuse the transmission software and result in TCC engaging or not engaging. Diagnose/repair/swap the gearshift mechanicals/electronics accordingly?
