I've been trying to determine what the correct flow in and out of the transmission is.
There is conflicting information on here and online, not sure if I'm mixing up the info, but could just use clarification.
I assume the top trans cooler line on the radiator is FROM the transmission and the bottom line is the RETURN to the transmission.
If anybody can clarify or provide info I'd appreciate it, thanks.

Transmission pushes fluid into the bottom of the cooler. Returns to the trans from the top.
I can only assume it's done this way to purge air from the cooler.

Page 77 I think has the flow for ya.

Wow fantastic info. Ok so here's what I did, I have the Hayes basic trans cooler set up AFTER the radiator, and I positioned it right in front of one of the twin air ducts/grille on the bumper. My concern is that will this cool off the trans fluid too much. Should I install a thermostat just to be safe. I live just south of Indianapolis so it does get pretty chilly down here in the winters.
Please let me know thanks!

I set mine up the same way as you and I live in Minnesota. I wouldn't be concerned about cooling the fluid too much although in the winter you don't need the extra cooling. You can always cover the transmission cooler in the winter to keep air from flowing through it.
My assumption is a thermostat in the transmission fluid line would deprive the transmission of fluid. I wouldn't do that.

If you are concerned, look into the LPD coolers. They bypass the cooler if the fluid is too cold.

So I installed a Hayden 402 transmission cooler that was somewhat small and easy to place. The best thing you can do for yourself is get a Hayden 397 fitting. This fitting will allow you to install the cooler without cutting into any lines. I installed my cooler on the passenger side (PS) of the front. I took off the radiator fans and front bumper cover. I oriented the placement of the cooler in front of the PS vent in the bumper, at least close enough for air coming through the vent to catch a majority of the cooler. I un-plugged the upper radiator trans cooler line, I then installed the fitting into the trans cooler port on the end tank of the radiator so then you're left with two pipe ends which are perfect for the tubing in the kit. I then used the included zip ties to run them through the cooler, condenser, and radiator. Removing the fans just help situate these, you don't have to but it would help with a larger cooler. With this setup you then run the cooler after the radiator, as I learned above. Pretty easy to do.
