The lower one should be your power steering cooler.

 

is it cheaper, do i need a special rad for that?

 

right BUT I know for sure that the top one is tranny! the bottom one is just a standard cooler, you can pick it up at any parts store. I don't think it has high pressure lines, so it should be easy to change

 

It's of course a seperate thing from your tranny cooler. The reason you probably thought it was your tranny cooler is you use ATF fluid in your power steering for these trucks. Look up the power steering cooler and see what you find.

 

ya it as leaking red so i was like ahh tranny lol guess i should have done so research first, thanks guys

 

no sweat, good call on the pics, saved you buying the wrong thing

 

EXACTLY. Pics are worth a thousand words.

 

should i replace the hoses when i change the cooler? i'm thinking yes

 

never hurts! it is cheap, and you will already have it all apart
