My DTS overheats while I'm driving but not when in park and
idle. Replaced thermostat, upper radiator hose, and coolant
reservoir and cap.. Only thing left is water pump but I have no
leaks???

In addition to what has already been done or suggested, the cause may be a radiator with low flow due to internal blockage. If the radiator is not allowing coolant to flow freely, heat will build up and cause this problem to appear more at road temp rather than idle temp.
I buy the car--if you in New York--I know how to fix it the dealer will only say head gasket- let me take a look first---call me 7183165935
