The high torque of your Cummins in conjunction with a better designed torque converter can transfer the torque with no slip. The flex plate is bolted to the crank shaft, then the converter is bolted to flex plate. The torque from your Cummins is transferred to the flex plate, from the flex plate to the torque converter then to your input shaft in the trans.
