2007–2021 Tundra Transmission Cooler Kit
$219.00
Towing, oversized tires, hot weather, and higher speeds can all add heat to your Tundra's transmission.
This kit adds a dedicated external transmission cooler using an FMD bracket designed specifically for the 2nd Gen Tundra. Each kit includes the cooler, FMD mounting bracket, hose, and installation hardware. Factory plumbing components are available as an option for trucks that need them. Transmission fluid is not included.
Why We Changed Our Cooler Kits
When we first started offering Tundra transmission cooler kits, we used a more expensive 19-row cooler because we assumed the premium cooler was the better option.
Then we actually tested it.
After seeing the results, it didn't make sense to only offer the more expensive setup. That's why the Single Cooler is now the setup we recommend for most trucks, while the 19-row Setrab remains available for customers who prefer the premium hardware.
Choose Your Cooler Setup
Single Cooler — Best Value
The setup I'd recommend for most trucks. It provides a substantial increase in cooling capacity without the cost of the premium cooler. Not compatible with our driver's side power steering cooler kit.
In our towing test:
211°F average / 218°F max
Want more cooling later? The single and dual cooler setups use the same FMD bracket, so a second cooler can be added later without replacing the bracket.
Dual Cooler — Maximum Cooling
Uses two stacked coolers for additional cooling capacity. This setup produced the lowest temperatures of any configuration we've tested. Not compatible with our driver's side power steering cooler kit.
In our towing test:
203°F average / 210°F max
A good choice for frequent towing, heavier loads, oversized tires, or anyone simply wanting as much cooling capacity as possible.
Setrab 19-row Cooler — Premium Option
Uses a Setrab oil cooler made in the E.U. with a black anodized FMD bracket designed specifically around the Setrab core. This bracket also includes vibration damping! Compatible with our driver's side power steering cooler kit.
The Setrab cooler is dimensionally equivalent to the Derale cooler used in our towing test, with the same overall thickness, row count, and mounting dimensions. Based on the similar size and design, we expect comparable cooling performance, but we have not yet completed the same towing test with the Setrab cooler.
Derale 19-row test results:
211°F average / 222°F max

2007–2018 Tundra
If your truck already has the factory in-condenser transmission cooler, the FMD cooler can easily be added to the existing cooling circuit.
Check the product photos before ordering to confirm your truck has the factory in-condenser cooler hoses:
2019–2021 Tundra
2019–2021 Tundras do not have a factory external transmission cooler. Toyota discontinued this cooling system for these model years, leaving transmission temperatures capable of reaching 240°F or higher, especially when towing or driving in hot weather.
These trucks require additional factory thermostat and cooler plumbing components. Select the OEM Plumbing Package when ordering. This package includes 100% genuine Toyota products.
