At idle with no load (in park) it takes a ridicules amount of time to bring it up to operating temperature.
The trick on a hoist is to brake torque.
The transmission builds thermal load rapidly when working against resistance.
You will be shocked at how fast the transmission builds heat from a cold start, when brake torquing.
Owners in the snow belt use this for getting faster climate control heat.
* Start the car.
* As soon as the engine is stable.
* Step firmly on the brake, and keep holding it.
* Shift to low gear.
* Accelerate to roughly 1500 - 2000 RPM.
* Hold the speed until the engine temperature hits 40°C.
If you start driving now, the heat will be comfortable.
