[Highbanked Hauler]

 I am putting new lines and an add on cooler on sons 440-727 and don't know which line is the hot one and which one is the return line at the trans.  Thanks !

I don't really think it matters does it? 

I put on a external cooler and just spliced into the lines...worked fine till I did the 4 speed swap

     Thanks, by the picture the return line is the  RIGHT or REAR line so with that the   LEFT or FRONT line  is the  OUT or HOT line. The line that comes out of the radiator cooler goes to the add on cooler then back to the transmission.  I can deal with that...
