I was wondering if any of you in cold climates have installed aftermarket Transmission Coolers with your radiator bypass. I've been looking around the internet and find no shortage of nice big coolers, but I'm concerned about the cold.

I live in Minnesota, and it gets plenty cold here in the winter so I was thinking something like this:
Tru-Cool MAX transmission cooler with external thermal bypass: Bulkpart transmission parts

Or I can just buy the thermal bypass....
Remote external thermal bypass: Bulkpart transmission parts



Anyone else dealt with the problem? Any Insights/Suggestions would be appreciated.

What problem is that? I have done the by-pass and there is no problem as far as cold warm up times go or hot running.

From what I've gathered... If you put in a much better/bigger cooler without a bypass the operating temp could be below optimum. I've heard this could also be harmful to the transmission.

That bypass allows the car to basically heat up w/o the cooler being used and then once it reaches 180 or up it goes through the cooler again. (although this transitions gradually, it's not just on/off)

The older frontier's used a thermostat bypass.When we would do a tranny flush you would have to get it hot for the bypass to open .

you can damage the tranny by running it too cold. a simple solution would be a jacket around the tranny cooler that limits air flow, like you see on the front of big rigs that cover the grill inlet for driving in cold climates.
