Rum, rum, rum@ 3,500 RPM
My E450 with V10 has a slight surging of RPMs at 3,500 and climbiing hills. Normal or something out of balance? New 8 months old 2015 chassis.

It's not clutch fan, doesn't stutter, not harmonic and weather not a factor. Again its downshifting and climbing hill or accelerating when 3,500 rpm
How fast are you going when this happens? Is speed relevant?
