TF a727 hub size

The extra slop doesn't effect anything. But TFs are NOTORIOUS for being difficult to install. The reason is that they have no internal provision to center the inner pump gear; it just flops around when the converter isn't in place; unlike Ford and Chevy. So....look inside the pump and note the position of the tangs by marking their location on the bellhousing. Then mark the location of the slots onto the front of the converter. Line up all these marks and try to install it. You might have to reach inside the pump with a skinny screwdriver to center the pump gear.
