So basically if it gets down into the 20's or teens at night, I need to just take it easy (which is what I have been doing when it was cold out west until the tranny temp read >70). That said, if I ever ride out the winter in Rapid City, then it would be advisable to install a bypass; otherwise...
I get the max temp discussion, too hot is bad ... but when its cold out, how long should I idle to get the temperature above ... what temp? Is 65F ok to start driving? 45? I have a post-radiator tranny cooler installed, and am planning to tow a 5000 lb travel trailer to Maine and upstate NY...
