After I turned this on, I traveled maybe 150 yards and looked to see what gear I was in and I was already in 5th. The smoothness of this drivetrain is unbelievable. No perception whatsoever of the shifting that occurred. The only time I can tell is when I stomp the pedal, or the very faint bumping sensation when decelerating to a stop.
My wife has a Pentastar Durango with an 8 speed and I thought that was smooth, there is no comparison.
