My 08 automatic 350Z had the radiator replaced at the body shop and I see by the paperwork they used an 06 from a manual. Once I get over them paying more for an older used OEM radiator than a new aftermarket I still need to be sure they are the same, does OEM Nissan put the Trans oil cooler in the manual as well as the automatic and just leave it plugged off? I see in some other Nissans/Infinity cars.

I will look once I have some time but thought some of you may already know.

 

No, they are not. As far as I remember radiator with auto transmission has a transmission cooler mounted to it and there is no mounting points on the manual radiator.

 

Update, they are the same, they just leave the caps on the Trans cooler when put in an automatic. Not sure what the other little cooler in front is, PWR steering maybe. Either way it seems mounted fine and the trans cooler lines go into the bottom of the radiator. Also they did use a new one just after market. I crossed the auto and manual and it came up same part number. Thanks
