HPD has you covered for reliable transmission temperature control. Many OEM setups route trans oil through the radiator or a coolant heat exchanger, which can raise engine temps under load and risk coolant–ATF cross-contamination if a failure occurs.

HPD’s oil-to-air transmission cooler uses a robust bar & plate core designed and tested to maintain stable temps during hard towing, hot ambient conditions, and off-road work.

• Avoids mixing engine coolant and ATF in the event of radiator/heat-exchanger failure
• Reduces thermal load on the engine’s cooling system when everything is working hard
• Dedicated airflow equals more consistent transmission temps under sustained load

• Reduced / stable transmission temperatures
• Prolongs transmission oil life
• Lowers engine coolant temperatures
• Reduces stress / strain on transmission components
• Can improve fuel economy when towing
• Helps extend overall transmission service life

• Bar & Plate Core: 300 × 200 × 50 mm
