1997 MAZDA 626 HEAVY VIBRATION

I HAD EVERYTHING THING YOU CAN IMAGINED REPLACED ON THIS CAR, HEADS, TRANNY, EXHAUST, MOUNTS, ALL SENSORS , ETC. THE PROBLEM IM HAVING IS THAT WHEN IN PARK THE CAR VIBRATES HEAVY, BUT WHEN I ACCELERATE ITS FINE UNTIL I COME TO A RED LIGHT OR A COMPLETE STOP THEN IT STARTS TO VIBRATE VERY HEAVY, NOW I TOOK IT TO THE SHOP TO GET AN EXPLANATION THEY TOLD ME IT COULD BE THE TORQUE CONVERTER, THEN I TOOK IT TO ANOTHER SHOP THEY TOLD ME ALSO IT COULD BE THE TORQUE CONVERTER, I TOOK IT BACK TO THE TRANNY SHOP THEY REBUILT THE TORQUE CONVERTER AND REPLACED THE RCI BUT IM STILL HAVING THIS HEAVY VIBRATION. CAN ANYONE SHINE SOME LIGHT ON THIS MATTER IT WOULD BE GREATLY APPRECIATED.
