And if it could be made adjustable, you could dial in the optimum operating temp.?
I am running a cooler with a 45000 lb gross rating, it has a non adjustable bypass that was in the kit for heating up the trans fluid till it warms up. My trans guy who got it for me say that is what they are using on the new trucks. My alum. Griffin Rad did not have fitting for the trans cooler. Ed ke6bnl
