Transmission Cooler Question
I stripped out my aluminum radiator transmission line threadin and the guy at the radiator shop told me he couldn't fix it so he recommended I get a Hayden 404 transmission cooler and run it behind the radiator. My question is, my trans line is a 5/16 with a 1/2-20 connection from what I can gather. Looking at the Hayden 404, would this work for me as far as line size and connections? Doesn't seem like it would but I figured the radiator guy would know what he is talking about.

Re: Transmission Cooler Question
I believe he's assuming you will use rubber transmission line to make the connection. It looks like the cooler has barbed hose fittings, not threaded.
On my truck I used all hard line with flare -> pipe fittings to connect the cooler. If you're interested I can dig up the model number, etc, of the cooler.

Re: Transmission Cooler Question
I bought one with npt connections and get fittings to the size and type you want. I used 6AN hose on mine.

Re: Transmission Cooler Question
x2 I mounted mine in front of the radiator and used the AN fittings.

Re: Transmission Cooler Question
If the radiator is out of the vehicle, go get a pipe thread to pipe thread or AN fitting and get someone to weld it in the hole of the radiator.

Re: Transmission Cooler Question
I will take some pics tonight. I used Adel clamps and they fit around the bends of the cooler and mounted them to the core support. then I got AN style bulkheadfittings and piped it through the core support. Hard lined the entire way. no hoses.

Re: Transmission Cooler Question
Here's a pic of mine - wasn't intended to be a pic of the trans cooler, but it's visible, so figured I'd share it.

Re: Transmission Cooler Question
I will get a picture of mine. I would mount it in front of the radiator. Behind the radiator the shroud would hit it.

Re: Transmission Cooler Question
If I was needing a cooler (to run without the factory in radiator cooler) It would be a plate cooler like on Dave's picture not the Hayden posted.
