i didnt mark my trannny lines when i pulled them off which one goes where or does it matter im gonna run a double tranny cooler with two fans one cooler is already in i have to get the other one and connect to it so matter or dont matter

 

I don't think that it matters which cooler is first or which dirrection the fluid flows through the coolers.

 

you want to have the trans fluid go through the original cooler in the rad first then to the other filters. Otherwise you will cool the oil then rewarm it in the radiator.. the cooler line closest to the front pump in the trans is the pressure line..

 

The outlet pressure line (trans front) goes to the rad drvrs side, the rad pax side goes to the aux cooler then back to the rear line of the trans.

 

ok ill check but i think the guy that owned the truck before did away with rad cooler thats why there was an extra tranny cooler
