Got a 700r4 im ny 63 and am installing trans cooler lines ,I know the top line on trans is the return line . Which side of radiator was the return drvs, side or pass side ? I am thinking the pass. side is return or does it even matter??
Plumb flow Into the Lower fitting and Out of the upper. That way the cooling passages are flooded with fluid and the cooler fluid is pushed up and out. Natural circulation and air flow work together to cool the liquid that way.
The top line on trans is the return the bottom line is press. when press. goes to radiator does it go on the drvs. side or the pass side ? after I get this I will plumb my return line into cooler and back to trans.
