Radiator for AT
 
Which one will be fit FBM turbocharged AUTOMATIC TRANSMISSION BRZ?

As I understand where is some difference in fitment between MT and AT...

What does it mean?

Note: Koyo All-Aluminum racing radiators are made for manual transmission applications only. Automatic transmissions will require an external transmission oil cooler.

Traditionally, automatic radiators have an auxiliary heat exchanger built into them to cool the transmission fluid. That said, this car has a different setup where the heat exchanger is external from the radiator. I could be wrong, but the AT and MT appear to use the same radiator for this application.

^Aftermarket radiators are usually MT unless otherwise stated; I know most WRX radiators were "not for AT" because they didn't have a place to cool the AT fluid, like the stock WRX AT radiator did.

The factory service manual shows the below as the oil cooler assembly for the TX6A automatic transmission. The unit appears to be a piece entirely separate from the radiator, thus radiators shouldn't be different between models (you'd think). The oil cooler is accessible once removing the No.1 and No.2 engine covers. I would add an aftermarket (Long Tru Cool; highly recommended line of coolers) unit in series with the stock unit such that you're not over-cooling, since AT vehicles usually have some functionality reduced until they reach proper temp.

So I'm so f...ing stupid, don't understand, why i can't install for example Koyo radiator? No additional holes on it? Or what?

Yes, it would not have a hole for the ATF cooler lines. However, Koyos website lists it as applicable to the At as well, so I would confirm with a vendor if that means it fits or it has the ATF cooling capability as well.

I have an AT. The MT and AT radiator are the same. So no problems installing the Koyo on your car.

I have the koyorad It says in the instructions to not install it on an automatic car. Koyorad said they were working on automatic transmission compatible radiator they may have it done I have had my radiator for over a year now.

It has one. It's the one in the picture above. It runs off coolant, but it is connected to the block instead of the radiator.

I have installed an aftermarket radiator. From the pictures, it seems the same with the koyo. I used a supposedly MT only radiator on my AT car. The AT radiator has the same outlets as the MT one. The coolant for the AT is run off the block. The people that installed the oem forester oil cooler discovered where the coolant is run off from. You can check my radiator install in my build thread.

Tye300 are you using the same MT koyo radiator on your AT?


EDIT: nevermind you posted right before me and answered. Thanks!!

Why not get an FBM one and call it a day? It works flawlessly
