I am not an expert on TC-1 torque converters or any torque converter, but I have one that was working well, but now does not. The driven side is flopping pretty loose. I think I may have lost my pre load. The driver also seems to be an issue. The weights aren't coming out as freely as they used to. Is there a TC-1 site/thread that might help?
