07-21 Tundra 5.7L Transmission Cooler Bracket
$139.00
If You Tow, Or Have Big Tires, You Need This
If your Tundra hauls heavy loads or wears bigger tires, this bracket is a must.
By the time the dash light comes on at 305°, it’s already too late—your fluid is cooked. And a complete drain and fill will cost over $200 in fluid alone.
Simple Fix. Big Difference.
This bracket lets you mount a real external cooler like it should’ve come from the factory.
- Designed for Derale or Setrab coolers (Derale available HERE)
- Solid, no-nonsense mounting—no zip ties
- Slim profile so you’re not blocking airflow
- Uses the factory thermostat (so you won’t run too cold)
Built Like Toyota's Should Be
- Laser cut from 1/8" aluminum
- Strong, simple, and made to fit
- Includes stainless hardware
How It Works With Your Truck
- Make sure your truck already has the factory transmission cooler (see photos)
- You can splice this cooler in series with the factory cooler, or cap off the factory cooler and run just this big one
- The factory cooler is built into your condenser or radiator depending on model year
- An external cooler makes a huge improvement over the “fluid warmer” in your radiator
Works With My Other Kits
Pair it with my Power Steering Cooler Bracket and save $10—because doing it once is smarter than doing it twice.
