I am doing my engine and tranny swap finally. My buddies and I took the motor and tranny out today and one of the tranny lines would not come off the tranny side. So I had to cut it. I am thinking of putting some -AN fitting's and braided line to go to a trans cooler. Does any one know what size fitting to use? And a suggestion on a tranny cooler.

 

The trans lines are 3/8 ... use a #6 line. You can buy a sleeve and nut to connect the AN fittings to your stock line, you just have to reflare the line or do like I did and use a compression fitting underneath to put a new end on with the sleeve and nut. My trans guy asked me how the hell I did it before he looked closely. BTW I used the stock radix heat exchanger (Setrab) for a trans cooler. I bought some #10 to #6 fittings at the local hydraulic shop. That cooler dropped my trans temps 40+ degrees. It rarely goes above 160.
