Beat me to it!!! Even though remanufactured converters are balanced during the rebuilding process (at least they are suppose to be!!) the balance tolerances of the flywheel, converter, and other parts can stack up and create a vibration. To prevent future issues, mark the driveshaft and converter mounting locations.
