I've never seen this before and can't find anything about it. I bought this new radiator from someone who didn't end up needing. I opened the original box to find the transmission connections are some bubble or flare bolt and not the pipe like it's supposed to be. I even looked up the part number to make sure and it's direct replacement and even shows the right connectors. I bought various barbed fittings and none will fit it. Not sure if I should just give up and by another one. Old radiator on the right.
