46re rebuild kit

They call it something else like a "range sensor" rather than "neutral safety switch. That change happened when they went away from the orange needle that is connected to the column with a string and went to more "LED looking" PRNDL indicator on dash. I'm not sure what all else is different between them other than number of terminals and shape of plug. I have read that the hole for the switch is different size and thread than the old 3 pin and there's an adapter sleeve that you can get to convert the 01+ style to the older ones where you could use it with the old 3 pin one (and you'd have to change the "rooster comb" on the valve body too) but there's no way to adapt older trans to newer body.
I've never tried interchanging across these years of transmission, just what I have read on forums.
