does my atf need to go threw my rad? or can I just get a bigger cooler?


I tow alot of ****(boat and work trailer) and while my tranny is out now is the time to mount up a new cooler and lines(bigger cooler???)

 

any input?

 

Your atf never goes thru your radiator, don't know what you mean there. its a separate cooler. but anyways usually the stock tranny cooler will do fine if you have it. You could probably mount up a bigger cooler if you wanted, but i don't see why you'd need bigger lines cause the inlet and outlet size on the tranny will still be the same anyways.

 

yes it does go threw the rad, out of tranny too the bottom of the rad out the top of the rad , down to the cooler then returns to the tranny

 

^no, it doesn't. It goes thru the cooler that is attached to the radiator. It can't go thru the radiator cause that would be mixing ATF and coolant in your tranny and in your engine, which would be very very bad.

Just so you have it straightened out that they are two totally separate things. So yes you can upgrade the cooler if you want cause it has nothing to do with the radiator.

 

correct the tranny cooler is separate its about 6x4 inches and its mounted low in front of the radiator, steel lines in and out cant miss it the other one is the powersteering cooler.

 

yes I know they dont mix but the line runs to the rad then the cooler my question is does it need to go to the rad first? or can I just add a larger cooler and skip the rad?

 

have a look at those lines one goes to the bottom of your rad,then too your cooler,and back to your tarnny

 

to answer your question the way you have it, yes you can just put on a larger cooler and skip the radiator.

But seriously how the hell would the atf cooler line be connected to the radiator without them mixing? I have never seen this on any vehicle ever, they are all completely separate.

 

they are on the side and there is a sealed unit inside the rad,i had one rot out on my explorer and the atf and coolant mixed.

see the two fittings,there is a pipe inside that the atf runs through and then it goes to the cooler on the front o the rad
