I've considered one of those t-stats, but my tranny doesn't have electronics to care about running cold, unless it's really cold. A 150* or 160* t-stat would be fine. I see no reason to keep it at 180* or hotter.
Transmission temps. Should I be concerned?

Simply blocking the airflow to the external cooler will work great for winter.

Nah. Automatic self regulating controls. Engineer the thing to manage everything. Absorbing heat to a controlled point, rejecting it beyond a given point. Below 180F it goes to the rad cooler, above the auxiliary gets put in line.
How much more cool can you get than that?? You can sit in the driver seat and imagine all those mechanisms just switching in and out as needed ..or not needed.
It's kinda like a mechanical ant colony .....

I agree that the mech thermostat is the ideal solution for ease of use, and covering all bases. I just wish I could find one that opened at 160* or so, rather than 180*.

180F is a perfectly acceptable temp. About the only thing left to do once you install it would be to size the auxiliary cooler properly so that 180F is your ceiling.
I was sure that one of the usual suspects made one in the 160F flavor, but I can't find it now.
Here's a diagram that I found interesting. In our view we'd be plugging either the normal cooler OUT port or the cooler IN port and bypassing that with a tee fitting. Permacool includes a diagram for setups that run too cool. It basically plugs the cooler return port on the thermostat and tee's in the return line from the cooler to the regular return line. It turns it into a blending valve instead of getting FULL cooling as long as the outbound flow is @ 180F. As this diagram shows, you can do that on either side of the thermostat depending on what you want to do ..either limit the output of the trans, or limit what you're sending back. With proper sizing and routing, you should be able to keep the trans within a pretty narrow range.
The missing port here would be a plugged out to cooler or plugged in from cooler on your basic Permacool or otherwise 4 port setup.
