Maybe a better oil heater would be valve to bypass routing the oil through the radiator/oil cooler, so it would just loop through the engine until toasty. It would also keep the oil at the minimum temperature say at highway speed in the cold as it could automatically reroute if the temperature ever dropped.
Same could be done for the transmission.
And there would be no worries with the oil sitting in the cooling loop/radiator during the bypass
The piping generally has threaded ends so you could try it without hacking pretty much.
