Ready to ship! These CNC press-brake formed .125" thick 5052 aluminum brackets are proudly made in the USA and are designed to make transmission cooler installation simple on automatic transmission 4runners. No drilling required — the bracket utilizes existing factory holes. Designed to fit the Hayden 678, Hayden 698, and Derale 13613 transmission coolers. Adding an auxiliary transmission cooler helps reduce transmission temperatures and heat-related wear during towing, heavy loads, off-road use, stop-and-go traffic, and other severe-duty conditions. Designed by an engineer. Built specifically for the 4runner. No universal brackets. No drilling. No guesswork. I buy the components in bulk and negotiate better pricing so I can pass the savings on to you. Cooler Options Hayden 678 Traditional transmission cooler providing additional cooling capacity. Hayden 698 Same physical size as the Hayden 678, but equipped with an internal temperature-controlled thermostat. The thermostat helps the fluid reach operating temperature faster in cold conditions while still providing additional cooling once the fluid warms up. The Hayden 698 is recommended if you do cold starts in colder climates. Hayden Thermostat Technology Installation No drilling required. The bracket utilizes existing factory holes for a clean, secure installation. Checkout the Youtube Videos listed in the media gallery for detailed install instructions and test results! Bracket Features Proudly made in the USA CNC press-brake formed .125" thick 5052 aluminum No drilling required Utilizes existing factory holes Clean, secure mounting solution Fits Hayden 678, Hayden 698, and Derale 13613 Bracket Only Includes USA-made transmission cooler bracket All required fasteners + installation spacer (goes in top hole) Hayden 678 Kit Includes USA-made transmission cooler bracket All required fasteners + installation spacer (goes in top hole) Hayden 678 non-thermostat cooler Additional 3/8" transmission cooler hose Edge trim guard (4) hose clamps Hayden 698 Kit Includes USA-made transmission cooler bracket All required fasteners + installation spacer (goes in top hole) Hayden 698 thermostat cooler Additional 3/8" transmission cooler hose Edge trim guard (4) hose clamps Complete kits require only approximately 1 quart of automatic transmission fluid to finish the installation. I recommend Toyota WS ATF or Valvoline MaxLife ATF. Optional Transmission Protection Upgrades ABA Stainless Steel Hose Clamps — Made in Sweden Upgrade your installation with genuine ABA stainless steel hose clamps, made in Sweden. ABA clamps provide consistent 360° clamping force, excellent corrosion resistance, and a smooth inner band designed to help protect the hose. Made in Sweden Stainless steel construction Smooth inner band Consistent 360° clamping Excellent corrosion resistance Ideal for 3/8" transmission cooler hose Reusable A hose clamp is a small part of the installation, but it's not a place I'd recommend cutting corners. Magnefine Inline Transmission Filter Add another level of protection with a Magnefine inline transmission filter. The Magnefine combines fine filtration with a built-in magnet designed to capture ferrous wear particles before they continue circulating through the transmission. This is the exact filter used by OEM's such as Ford after transmission replacements. Fine filtration Built-in magnetic particle capture Designed for automatic transmission fluid 3/8" hose connections Compact inline design Helps protect transmission components Replaceable during service To be secured by user with cable ties or other means Magnefine P/N 3810000 Gold Plug Magnetic Transmission Drain Plug — Made in USA Link to purchase on my website Make your next transmission fluid service more effective with a Gold Plug magnetic drain plug, made in the USA in Montana. Gold Plug machines its drain plugs in-house in Montana and uses high-strength magnetic technology to capture ferrous wear particles. The powerful magnet captures metal particles suspended in the transmission fluid, allowing debris to be removed during routine fluid service. Made in the USA Machined in Montana Stainless steel construction High-strength magnetic tip Captures ferrous wear particles Helps keep metal debris out of circulation Reusable Simple bolt-in replacement Gold Plug MP07 M10x1.5 Magnetic Drain Plug The magnetic drain plug captures debris inside the transmission, while the Magnefine filter provides ongoing filtration of circulating ATF. Veepeak OBDCheck BLE Bluetooth OBD-II Scanner Link to purchase on my website I strongly recommend monitoring actual transmission temperatures, especially when towing, wheeling, or operating your vehicle under severe conditions. The Veepeak OBDCheck BLE Bluetooth OBD-II adapter can be paired with a compatible free or paid phone app to monitor transmission temperature data directly from the vehicle in real time. Instead of relying on the factory temperature gauge, you can see exactly how hot the transmission is getting and how effectively your auxiliary cooler is controlling temperatures. This is the OBD-II adapter I personally use for testing and monitoring my 2026 4Runner. Recommended Apps For vehicles that support it, I recommend the free Torque app for a simple, easy-to-use setup. For more advanced monitoring, I recommend the free Car Scanner ELM OBD2 app. During my testing of the latest-generation 2024+ Toyotas, Car Scanner ELM OBD2 was the only app I was able to get to display transmission temperature data, making it my recommendation for the 2024+ Tacoma, 2024+ Land Cruiser, and 2025+ 4Runner. Vehicle Compatibility The Veepeak adapter is compatible with OBD-II vehicles, which generally includes U.S.-market vehicles from 1996 and newer. However, the data available through the OBD-II port varies by vehicle. An OBD-II port does not necessarily mean the vehicle provides transmission temperature data. Important for older 4Runner owners: The 1996–1998 4Runner does not provide transmission temperature data from a factory ATF temperature sensor, so transmission temperature cannot be monitored through this adapter on those model years. For supported vehicles, an OBD-II adapter is one of the easiest ways to stop guessing and start monitoring actual transmission temperatures. Built for the 4runner USA-made bracket. USA-made Gold Plug. Swedish-made ABA clamps. Quality components selected specifically for transmission cooling. Make your auxiliary transmission cooler installation clean, simple, and completely bolt-on — with no drilling required.
