Hayden’s new patented internal pressure by-pass coolers allow the vehicle’s transmission to reach optimum operating temperature quickly by routing the fluid through the by-pass channel of the cooler until fluid temperature increases. This new design allows vehicles in colder climates to reach proper operating temps faster which improves fuel economy and helps reduce friction of internal components. Hayden’s internal pressure by-pass design incorporates an integrated valve that eliminates the need for external valves and additional plumbing at installation.
