I agree in letting the trans do its job. IMO only to take it out of OD is if the trans keeps looking for a gear. Mine has 3.73 in it too and I don't worry about the RPMs when it down shifts. It don't get that high. Actually I tend to back out of the throttle a little and maintain about 55 up the grade. It will do more I just don't over push it.
