Mine sits between 1/4 and halfway.

Twice it has started to overheat, at about 3/4 of the way before I shut it down. Both times it happened after pulling my boat, and then sitting at the loading dock for 15 minutes with the A/C pumping and 90+ degrees outside. I'm thinking about adding an external trans cooler. I'd highly reccomend you doing the same. I think the trans is getting hot, and since the radiator cools the trans fluid through the coolant, it starts overheating.
