I have a 400 tranny ready to put in my GN. I have a Precision 9.5" TC to put on the tranny. Problem is it wont go on. It slips down onto the first shaft then stops. I counted the teeth on the splines and they match. Everything looks like it should work but no matter what it wouldn't go on. After trying and trying I noticed that the only place that it looked like it may be hanging up is not the shaft but the bushing on the tranny right behind the o-ring. It seems the bushing is a bit smaller than the neck of the TC. At least I am hoping this is a bushing. Can this be corrected by removing it and putting the right one in??
