Shift overlap feels more like a binding as the trans shifts as two different elements are applied at the same time.
I was just in a 440/ 727 car that had a strong shift overlap feel on the 1-2 upshift, never felt that before! What causes that? The 1-2 upshift is only applying the front band unless the valve body is applying the rear band in first. So if it's a rear band apply valve body or you were manually shifting a stock valve body then the problem is timing the rear band release and the front band apply. This is one of the reasons why all the original manual valve bodies were reverse pattern.
