if its happening at 30-40mph then its not your differential clutch, as its already disengages at 6mph.
what you probably are feeling is either worn motor mounts, or chain slap from the CVT transmission.
your cvt transmission has a metal chain/belt that connects two ever-changing pulleys. if you abruptly let go of the petal, the engine's power gets cut, that stops spinning the input shaft of the transmission as fast as it was spinning, before letting the throttle go, but the pulley on the output shaft of the transmission is still carrying speed from the vehicles inertia - so something has to give right? that chain that connect the two pulleys in the transmission flexes and causes a slight cut in power as the engine/transmission catch up with the inertia and when the steel belt/chain is forced back into its normal position it causes a thumbing noise.
