As I wait on a new radiator to arrive, the thought of bypassing the OEM tranny cooler, and running the aux cooler with built in thermal bypass by itself, crossed my mind. Since I'm in FL, we rarely see super cold temps. The few times we get near the freezing mark, is overnight during our short 'winters', and the truck is garage parked. So I don't think I'm gonna see the scenarios where the tranny fluid needs to get warmed up by the engine coolant.
For the most part, my drives aren't very long (distance, or time wise) usually under an hour. The transmission temp tends to read 20-30 degrees below the coolant temp. On the rare occasions I do longer trips out of town, I'll see the tranny temp climb after being on the highway for a couple of hours, then hit heavy traffic with a lot of idling, so not much air flow. One time I remember it getting up past 210, which I'm sure is still acceptable, but it's considerably higher than what I'm used to seeing, so that made me nervous.
Anyone know of any cons to this idea, that I'm missing? The return line is already connected to the aux cooler, so moving the other hose to the feed line wouldn't be too hard. Can't remember from when I did the filter and fluid change, how much dripped out when the lines were disconnected, so I'll have to make sure I have some extra fluid on hand just in case.
