Transmission, torque converter, updated starter questions

I was getting antsy, so I just put in a couple of quarts of ATF into the TC and lined it up with the keyways and it slid in and bottomed out. In order to see if I was fully seated, I mocked up the stock starter to look at the gap between the flywheel and starter gears...Pictured Does that look good? When I spin the TC, it does not rotate the rear driveline studs. When I rotate the smaller splines on the Trans with the TC off, the driveline studs do rotate....Is this the "stall" in the TC, or am I not seated correctly to engage those driveline splines? Thanks
