How did you confirm that, exactly? There's really only one accurate way and you have to have a manual valve body to do it. You can fairly close without one, but it will never be right on.

The first time I ran it from a dead stop in drive but I wanted to confirm/compare and the 46rh has a tf2 kit in it and I verified it in 1st gear to be sure it would be close. I know it’s not a true manual valve body as it can and is driven in drive quite frequently but it shifts very well both ways. I have to assume it’s pretty close.
