Add on Transmission cooler with fan

[TDRdodgeman784]

I got a add on transmission cooler with temp switch and fan. The directions tells me to mount the cooler under the pickup bed and take the hot line out of the transmission and put it into the new fan cooler then into the antifreeze cooler then to the front air cooler then back into the transmission. Now that dont sound right cool the fluid then heat it back up in the antifreeze cooler then cool it again in the air cooler up front. I think it should go from the transmission threw the temp switch then to the antifreeze cooler then the front air cooler then to the add on fan cooler then back into the transmission. if someone has this or seen this add on cooler with temp switch and fan can you tell me the order you have the coolers in and temp switch in and how good it works .

TDRdodgeman,Here in the winter months the fluid must reach 80* plus for the software Dodge has for extreme cold shift patterns. The factory system is robust the Auxiliary cooler is sufficient for even the most extreme conditions, I would install a switch to allow fan engagement 1st. Thanks to Matt400.

Also the factory system has a thermostat operated bypass installed, this means you would have to removed it to allow the additional cooler to work properly.
