I got a used tranny cooler off my uncle, It did not come with any hose does any one know the size hose and length I will need to install this?

 

I just did this, and I don't recall the size (but you can just take it to any parts store with you), but I used about 5 feet. You're just going from the back of the radiator (lower passenger side) to the front of the radiator and back.

 

So about 5 ft total?
