Keep your transmission temperatures under control with the Hayden 698 High-Performance Transmission Cooler. Featuring an efficient stacked-plate design and an integrated thermal bypass, the Hayden 698 provides excellent cooling performance while helping prevent excessive cooling during cold-weather operation.

Unlike traditional transmission coolers, the Hayden 698 features an internal pressure-activated bypass system that allows transmission fluid to bypass much of the cooling circuit when fluid viscosity is higher. As the fluid warms and viscosity decreases, more fluid flows through the cooler for improved heat dissipation. I've tested this against many larger coolers and it performs extremely well for the price and size.

Key Features

High-Efficiency Stacked-Plate Design: Provides excellent heat transfer in a compact package.

Integrated Thermal Bypass: Pressure-activated bypass helps reduce excessive cooling of cold transmission fluid without requiring an external thermostat.

Heavy-Duty Construction: Durable aluminum construction designed for reliable performance.

Compact Design: Ideal for applications where mounting space is limited.

Universal Application: Suitable for a wide range of automatic transmission cooling applications.

Why Choose the Hayden 698?

Excessive transmission temperatures can accelerate fluid degradation and increase transmission wear. Adding an auxiliary transmission cooler helps manage operating temperatures, especially during towing, off-road driving, and demanding conditions.

The Hayden 698 combines efficient stacked-plate cooling with an integrated bypass design, making it an excellent choice for vehicles that experience a wide range of operating temperatures.
