16-pass 6061 aluminum tube-and-fin auxiliary transmission cooler for vehicles with 1/2 inch ID cooler lines, rated 145 PSI working pressure.
This is a 16-pass tube-and-fin auxiliary transmission cooler built from 6061-T6 aluminum. ATF runs through the tubes while the fins pull heat off and shed it into the airflow, dropping fluid temperature before the ATF returns to the transmission. It is rated for 145 PSI working pressure and -40 to 257 F.
It is sized for vehicles with 1/2 inch ID transmission cooler lines. The standard install is in series after the radiator cooler: cut the return line, run the ATF through this cooler, then back to the transmission. Measure the space in front of the radiator or A/C condenser before you order, since a 16-pass core needs real room and clear airflow.
Only the cooler is included, so plan on hose, clamps and a mounting kit sized for your lines. An auxiliary cooler is the first thing to add on any truck that tows, plows or sits in traffic, because heat is what kills clutch friction material and varnishes valve bodies.
