Abstract
A coupling interconnecting an engine and the impeller of a torque converter in a vehicle powertrain has first and second inertia masses interconnected by a spring and friction isolator. The coupling is effective to decrease the inertia mass of the engine and to increase the inertia mass of the transmission thereby providing a change in the natural frequency of the vehicle powertrain.
