I installed a DIY ATF cooler using 5/16" dm x 84" steel tubing coiled 3" in diameter, looks like a suspension coil spring, inserted between the inline ATF filter and tranny sump. Strapped the coiled tubing with plastic straps inside the bumper where air can cool it down.

Will test on a long drive kung may pagbabago sa acceleration pag mainit na ang ATF. The coiled tubing will somehow help cool down the ATF. Anyone knew which is better conductor of heat, steel or copper tubing?
