Sorry last426, I forgot to list A36...your car "should" have one but like Scott said its seems to be hit and miss.

I helped restore a 70 hemi GTX w/A33 and no cooler. It was a very original running and driving car and I remember being suprised that it didn't have the cooler. But then a friend had a 71 hemicuda, auto/3.23 car and it had a P/S cooler but didn't have a transmission cooler!
