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.

Roy,
Same thing happens with a scraper. When loading ~ 30sec to 2 minutes, you can easily overheat your trans, (auto). When working in hard ground you always watch the trans oil temp. Conversely, you can leave it in neutral all day at idle & it wont get to operating temp. The TC is a big dissipator of heat. If there is any moisture in your trans fluid, it soon boils & you run out of drive quickly.
