one radiator for all tj engines and transmissions?

hi jeepers!!! the radiator of my jeep is about to blow on the side and i would like to get an upgraded aftermarket cooler. i have a 2.4l engine on my tj with an auto tranny. i dont know why my choice of radiators are limited (it always shows coolers for the 2.5 or 4.0).
should it be only one radiator for all the jeeps? does the transmission plays on the choices? im completelly ignorant about. i wanna know the most possibly since i wanna make a wise buy (duh, like im the only one).
right know im adding water everyday but i wanna check the choices i have.

thanks anybody in advance.

Yes, you're going to need one for an automatic transmission because it has lines going in and out of it for the AT fluid.

Buy Mopar!

Rokmen TT, Rokmen control arms, Novak NV241 cable shifter, JKS 1.25" BL + 1" MML.

Anybody can take advice if it doesn't interfere with their plan.

A spectre rad is the same for all models, as far as I know. I imagine OEM would be the same too; the spectre includes an AT cooler, but if you have a manual you just leave it plugged.

X2 OEM is the best you can buy for your JEEP.

It's the same radiator. If you had a manual trans, there would be extra holes you would not have used.

Why do you feel you need an upgrade? The stock radiators cool just fine. As mentioned, OEM is probably the best option. Depending on how you use your Jeep and how mechanically inclined you are, you should not rule out aftermarket stock spec radiators from any given auto parts store. I choose aftermarket because it is cheaper, free replacements, and I'm willing to do the work myself.

Yeah, because you will need those free replacements frequently thus building your wrenching skills.

Which is why I said he should consider how mechanically inclined he is and how he uses his Jeep.

I got 110,000 miles out of my aftermarket radiator, and 150,000 out of the original OEM. I am okay with replacing my radiator every 110,000 miles if it is free. They give you plenty of warning when they are ready to go. I would not be okay with replacing it every 30,000 miles.

You did very good then. Never hurts to keep up on your wrenching skills.

My OEM does the exact same thing for about half as much $$$. Doesn't matter if a radiator holds 900 gallons or 2 gallons. If it cools to around 210 then that's all it can do. Oh yeah, mine doesn't leak either!!

The thermostat controls temperature. The OEM radiator is capable of cooling to well below 210; the thermostat keeps that from happening because the ideal temperature is 210. Cooler isn't necessarily better. Your engine and its' systems are built to a very specific design to optimize fuel efficiency, life of the engine, etc.. It expects to ramp in temperature at a certain rate and for the radiator to cool at a certain rate with the thermostat controlling it to the optimum temperature. It isn't going to perform any better because you install a radiator that "cools better".
