Automatic Radiators?

Any1 know of a brand that makes radiators for automatics? Checked into koyo and fluidlyine and neither of them do. Any suggestions? Also does the efini y-pipe fit with stock 95 turbos? And any1 know of a site where they sell them polished, rx7store.net has the y-pipe but its not polished

AWR makes them for Automatic FD's. It the same one they make for Mazdaspeed (5 speed).

Here's the link. http://www.awrracing.com/pages/cooling.html. I'll be buying and installing mine this winter :-)

The only difference with the automatic radiator is the loop in the bottom of the radiator to cool the transmission fluid. Might actually be better off with a manual transmission radiator and a good aftermarket tranny cooler - maybe even put the cooler where the 2nd oil cooler would go. Keeping tranny fluid cool is a MUST on an automatic for long life.

Not to mention that would likely be cheaper .

good idea...so good that the mazda engineers already thought of it. A second oil cooler already occupies the passenger side duct, functioning as a trans cooler. It looks identical, but I do not know if it has a built in thermostat like the oil cooler.

See the third response above....

BTW: The AWR is around $550.00 (Expense but IMO well worth it.).

I would suggest doing what I did, Buy the manual radiator, clean your auto tranny cooler on the pass side really good and install a Summitt Racing 17" rail cooler as an addition. Also install a Trans temperature gauge. Mine rubs @ 130F while tooling around town in 90F weather.

From what I heard, the automatic radiator does not cool the fluid. There is a seperate transmission cooler on the right side of the radiator. (I think it is on the right.) I think the mazda engineers just used the radiator as a way to conserve piping. It just transports the fluid from A to B.

And why do almost every other automatic tranny vehicle in the world have their tranny cooler built into the radiator - in many cases the only cooler, like on my Civic's radiator I replaced this past weekend?

It's not that it was not meant to cool the tranny fluid, but that it generally does not do a good job of cooling the fluid well - hence the additional tranny cooler on the FD.

FD3SR1: Yes, you simply disconnect the tranny fuid lines. I have the first auto tranny specific radiator that AWR built, which I had to lobby him for and wait 3 months, and have since done a tranny swap.
