OK, so I will try and attach a photo here shortly now that I got all three lines removed from the truck. It's only been a couple months since it's been running.

While driving at highway speeds I had a lot of smoke and burning from under the hood, i pulled over to check and I was dripping trans fluid. Since i looked under there and it was so far forward I figured out it was coming from where the two lines that clamp to the bottom of the radiator housing are. The dissimilar metal/plastic is where they corroded and one ended up getting cracked the other pitted pretty bad.

While I was under there and finally got them removed I also removed the 3rd line which runs from the transmission (bottom of two) to the top of the radiator. This 3rd line has two threaded and flared ports at both ends, the other two that actually went bad have a threaded end and a "nipple" end because they go right into cooler hose.

I started looking up the parts and AAP, AZ and NAPA all list the parts on their site but when you try to check out they say they are unavailable. I went so far as to look up Dorman online and those part numbers to see if I could order direct... no go. I went to the guy at AAP and he sold me 3 straight lines, a pipe bender and flare kit, i figured since I got out for under $50 it was worth it. Let's just say this was the weekend I was supposed to do the work and 3/8ths lines are not easy to get those tight angles on.... back to the drawing board.

Any ideas where I can find them, if there is a good alternative, maybe flex-line/performance parts from somewhere that I can order/build out to my needs? I'm asking for others advise because I'm not exactly sure all that I would need. Another friend suggested I find a hydraulics place around here and give them my lines to duplicate. Not sure the cost or estimated cost, but I know how difficult the lines were to get out so I was hoping there was a legitimate "flex" alternative.

Any thoughts, suggestions or help would be greatly appreciated, I would love to have the truck back and running here shortly. It seems this year has just been a bad year for and me...

 

Mine are leaking too and my truck is a 2010 that has been rustproofed every year!
The lines are only about $20 each at the dealer, so I think that is the way to go.
I asked the dealer if they sell a lot of these and they said "yup, that's why we stock them"

 

So I got the lines and I need to know which hose goes to which line at the front. One goes to the rh side of the trans the other to the middle of the radiator. Below is a link and I want to know from others how theirs is hooked up because its 50/50 I got it I right.

Both lines are different and only fit one place.
Or did you make your own?
Does this diagram help?
What kind of ATF are people using?

 

thanks, that helped out great!
