Expert Reply:

The best transmission cooler for your 2021 Toyota 4Runner is going to be the Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets - Class III - Efficient item # D13503. The radiator-style, plate-and-fin heat exchanger provides increased surface area so that fluids can spread out along the finned chambers to cool faster. Bigger is always better when it comes to transmission coolers. The Derale measures 11" wide x 8-3/4" tall x 7/8" deep. The transmission coolers are pretty universal so I have attached an installation video of this cooler being installed on an SUV.
