Frequently Asked Questions

Do automatic transmissions need a cooler?

Yes. Automatic transmissions generate significant heat during operation, and without a dedicated cooler, fluid temperatures can rise to levels that degrade the fluid and damage internal clutch packs, seals, and solenoids. A transmission oil cooler maintains safe operating temperatures, extends fluid and component life, and is especially critical in heavy-duty, towing, or high-cycle applications like construction equipment and commercial trucks.
