Hayden Automotive Transmission Cooler OC-1679 — Extra Heavy-Duty Cooler for Towing & Commercial Use, High-Flow Core

The HAYDEN TRANSAVER PLUS-COOLER OC-1679 is an extra heavy-duty transmission cooler designed to reduce fluid temperatures and help protect drivetrain components under sustained load.

This transmission cooler from Hayden Automotive combines a robust, high-capacity core with reinforced fittings and a compact mounting footprint to deliver dependable cooling where automatic transmissions or auxiliary systems run hot. Engineered for heavy-duty use, the OC-1679 is built for trailers, towing, commercial vehicles, and performance applications where prolonged heat exposure shortens fluid and component life. The design focuses on efficient heat transfer, durable materials, and straightforward installation while remaining compatible with many vehicle setups.

How does the OC-1679 improve transmission performance during towing?

By increasing the surface area available for heat exchange and circulating transmission fluid through a purpose-built core, the cooler helps keep operating temperatures lower during extended towing or heavy loads. Lower fluid temperatures maintain more stable hydraulic properties and can help reduce wear under stress.

• Extra heavy-duty core for greater heat rejection
• High-flow design to preserve fluid circulation
• Reinforced inlet/outlet fittings for secure hose connections
• Compact profile that fits behind bumpers or in grille openings

What makes this unit durable enough for commercial and off-road use?

The OC-1679 uses rugged materials and construction techniques intended to withstand vibration, debris, and repeated pressure cycles. Critical junctions are reinforced and the finish protects the core from corrosion in harsh environments.

• Thick-walled tubing and reinforced brazing points
• Protective external coating to resist corrosion and road grime
• Heavy-duty brackets and mounting points for secure installation
• Engineered to tolerate frequent temperature cycling

How straightforward is installation on a typical vehicle?

The cooler is designed for relatively simple installation using standard hoses and clamps; many installers can fit it using common shop tools. Hayden provides clear dimensions and mounting options so you can plan placement and hose routing without fabricating custom brackets.

• Predefined inlet/outlet locations to match common hose runs
• Standard-sized ports compatible with commercial transmission hoses
• Multiple mounting points for flexible orientation and fitment
• Compact footprint to fit in tighter vehicle front-end spaces

Will this cooler work with my transmission fluid and system pressure?

OC-1679 is built to handle typical automatic transmission fluid types and the pressures found in most transmission cooling circuits. It’s important to verify compatibility with your vehicle’s fluid type and consult hydraulic specifications for high-performance systems.

• Rated for standard automatic transmission fluids
• Designed to operate under typical transmission cooling pressures
• Suitable for auxiliary cooling or as a supplemental unit
• Check vehicle-specific requirements for best results

Who is this for: The HAYDEN TRANSAVER PLUS-COOLER OC-1679 Extra Heavy Duty is aimed at owners and operators who push their vehicles beyond light-duty driving—tow truck and trailer owners, commercial fleet managers, off-road enthusiasts, and performance vehicle builders. If your vehicle routinely operates under high load, long climbs, towing, or sustained high-speed conditions where transmission temperatures rise, this cooler offers a durable, high-capacity option to help manage heat. For standard daily driving without heavy loads, a lighter-duty cooler may be adequate; consult a technician to determine the right fit for your vehicle and application.
