I have a auto 1JZ SC300 that now has a cracked radiator. I've been reading and see that people are using the MK4's aluminum radiators from companies like Fluidyne, mishimoto, koyo. But they all seem to be made for manual transmission.

I was wondering if there is an aluminum radiator out there that has the tranny cooler built in? What are my radiator options with an automatic transmission?

thanks

Get an external tranny cooler. It will be more efficient.

Where would I install it? And how much does that add to the total price? Because the radiator alone will run me $300+

You can put it anywhere u want but the best place is behind the bumper. It will get more air.

Any recommended transmission coolers out there? Maybe one that most SC3 guys are using, or something. Because there are tons of different ones for sale. Trying to find the most efficient and most cost-effective one.

Just go to any auto parts store. And purchase one.

ill take a look at my radiator tonight (mk4 koyo) and see if it has the built in tranny cooler....I forgot if it does or not but I think it does. You just have to specify its for an auto when ordering..

+1 with everyone on top. All you need is an external tranny cooler if you run an aluminum rad and just run it where it will catch the most air. I am running a mishimoto with their external tranny cooler on mines. Everything works good. I just put my tranny cooler right in front of my rad since thats where most of the air is going.

Saw that thread, but i couldnt recognize where on the car he put the cooler from the pics. Im guessing its on behind the front bumper somewhere.

Also decided to go with a Mishimoto radiator and a Hayden rapidcool 1677 transmission cooler.

Hopefully eBay guy will accept my offer of $200 on the mishimoto. And the cooler ended up being $45. Not too bad.
