Can anyone tell me where I can find an upgrade radiator for the automatic FD?

I've heard Mazdaspeed makes a performance radiator that will work with the autotranny cooler. I'm looking into that myself actually.

 

Get a separate tranny cooler. Then you can get whatever radiator you want.

 

fluidyne for the man trans cars works just fine. you can run an additional trans cooler if you want. but so far I haven't had any problems. just take the lines that went to the radiator and tie them together. you still have the main cooler at the front of the car for cooling. the lines going to the radiator work as a trans warmer so if you don't drive in the snow or other cold climates your fine.

When it comes to auto trans coolers B&M is THE company.

I run a Koyo and bypass the radiator without any problems as well. I also added a thin secondary oil cooler behind the factory cooler, but I doubt it's necessary.

 

I have one of their copper/brass radiators (fits automatic) for sale - link:
