Has anyone else run into this? I bought a new stock replacement radiator from AC-Delco p/n 20269. I found that the fittings for the new transmission cooler are wrong. Original OEM fittings are 1/4" NPT. This is where the 90 degree adapters screw in that adapt the 5/16" flare trans lines to 1/4" NPT for the OEM cooler. The new radiator I bought was made with 5/16" flare fittings for the cooler. And guess what? They don't make a 90-degree 5/16"-flare-to-5/16"-flare adapter.
