first check thermostat sensor, a lot of them go bad, (dash cluster gauges) also they have had bad gauges. so if its not boiling over which you will see and hear?? its prob a sensor bad giving a false reading. also never hurts to check trans fluid?
If it spikes as soon as you shift and goes back down, it's not running hot. I'd replace the sensor, it should be on the cylinder head. Though, a truck isn't going to go from 185 to 250 in the few seconds it takes to shift.
