Not sure on the Nissans, but all my old autos had a trans cooler built into the rad. Manuals I ass-u-me wouldnt unless the same side tanks are used to save $. I had a Saturn SC2 Auto bust a rad and the town only had a manual in stock, not knowing the diff I bought and was not happy when I went to connect the trans lines. Luckily I had a PS cooler laying around which probably worked better.
