So I finally got the trans cooler installed. I managed to get the larger Hayden 699 to fit which was a bit of a challenge since I wanted to leave as much room for a winch as possible and not use the hood latch support brace as an attachment point for any of the brackets (since that would have to be removed to fit a winch). I used foam tape as suggested above and I'm pretty happy with how it all turned out. Now I just need to wait for warmer weather to see how much of an overall improvement it'll make.
