Help with tranny cooler
I have a 2002 7.3 PSD Superduty. I got a Large Tru-Cool tranny cooler from a friend and want to install it because I tow a 5th wheel. my question is; has anyone installed one of these in line with the stock cooler? If so, which line on the stock cooler should be run to the Tru-Cool cooler. Or is it better to just run the Tru-Cool? Does running two coolers like this reduce any flow that will cause a problem? Thanks for the help.

On the bottom right of the radiator, looking from underneath, you will find a short hose splice in the trans cooler line. You would separate this splice and connect your hoses from your TruCool to the ends of this line. This will put the TruCool in a series with the other trans coolers. I have mine installed this way with no problems, using the Dieselsite instructions. Any other questions, just PM me.

i installed a tru cool about 1 1/2 years ago, it is about 12x12x1 in size, my question is when i installed it (if i remeber correctley) it never had markings for the hose connections on the cooler itself indicaiting in and out, does it matter which hose was to go where? i hooked the cooler in series with the stock one, everything seems fine with my truck and tranny.
