That's what I meant, really. If I'm doing 40 mph turning 1500 rpm in 5th, I'd be turning maybe 2000 RPM doing 40 mph in 4th. So the diff DOES know what gear the tranny is in. So, 1500 rpm in 5th could be a unique event where the diff would groan due to vibration or the way the gears mesh because of that particular combination...
