I agree, the speed up and slow down would not affect the rest of the vehicle so it's still happening but no longer connected to the engine speed. So many new wrinkles in my brain!When not in gear the output on the transmission is not being forced to run at a constant rpm from the engine. The transmission output can know speed up and slow down as it is driven by the front end, although this could still produce some vibration and weird sounds from the driveline banging back and forth as slack is taken out one way then the other.
