im trying to find out what transmission line flows to the tranny and what line flows to the radiator?? starting from the top line on the radiator or does it not matter how i hook them up to the cooler?..thanks in advance

 

take off the top line and give it a quick bump u will see were it is coming from

 

mine goes in the bottom and out the top of the radiator . but i own a older 96 truck

 

Comes out of the top of the radiator through the cooler and back to the trans.

 

ok, so top line is feed to the trans?

 

cant bump it since no tranny in

 

Trans fluid travels through the bottom fitting through cooler in radiator and out top fitting and then through aux cooler and back to trans.
