727 trans won't seat-up on 440

Ok, well I counted the splines first thing. I THINK that's where my problem is. It was hard to count the TC splines though. The trans is 27 on the big gear and 23 on the smaller. On the TC I got 27 on the larger set and 24 on the smaller one. The TC collar isn't engaging the two "tabs" inside the trans either (front pump?). Does that sound right on the spline counts?
