Tru-Cool MAX, Super Duty Transmission Cooler kits

Tru-Cool Max transmission oil cooler has durable brazed aluminum construction and is designed for those applications that bypass the internal tank cooler for extra cooling or due to contamination.

Tru-Cool Max can also be installed in series for those applications requiring maximum cooling capacity.

WARNING: If vehicle is operated in temperatures below 32ºF or 0ºC the cold weather bypass will be required when using Tru-Cool Max coolers.
