I see koyos are only for mt, but if you get a seperate trans cooler your okay. I was wondering if there are any out there that exceed oe...not like the koyo replacement, but all aluminum with the cooler built in.

Thanks for any links

No one makes a high performance replacement. Just add an external cooler, it's simple since the hoses are right there.

Thanks but not really looking to purchase right away, but something I wanted to look into. I was wondering though, do the koyo replacements offer any better cooling than stock, or is it just their all aluminum models that do? Cause I know that version is suppose to work with auto and manual.

This is arguable without concrete data, although generally larger radiators, esp. aluminium ones, tend to dissipate heat better than smaller radiators.

Cause I know that version is suppose to work with auto and manual.

What version?


If you are auto, I recommend just getting an OEM replacement with auto cooler lines built in.

Not the full out racing one if thats what you wanna call it, I'm talking about the one with the plastic end tanks and aluminum core. I saw someone said copper transfer heat better, but the only copper model I saw was for sr.

I was looking at the aluminum one with the plastic end tanks, but wondering if it would be any better than stock. My rad is not broke, but I'm just wondering if the koyo replacement would cool better, if it's not the all aluminum version

I wouldn't. Shit sucks at cooling the AT.

Get a M/T radiator and a Tranny Cooler kit. AT will last a lot longer.

That's outside the scope of the OP's question:

Of course if you get a larger trans cooler than it will be better than OEM.

Pick your poison. Just make sure the installation is done correctly.
