oh, I can make this easy if I understand your post.
a 1993 chev van should have the early connector on the trans that has a threaded retainer in the center. These were changed in 1994 model yr
You post the van has the 'newer style' connector. This would be a push on connector , no threaded bolt or screw used.
the push on connectors all fit each other if the retro fit was done properly on the van.
so... if the trans and the van have the push on connector , it all works.
The trans for the 1993 van would also have both cooler lines up near the bell housing
Yesterday is history.
