Tundra News

As some of you may know, the 2019-2021 Tundra’s and Sequoia’s do not come with a transmission cooler. Instead, they have a heat exchanger that uses the hot coolant from the engine in an effort to cool your transmission. This method of cooling is not effective for many owners that tow, off-road, or just live in a hot climate. You may not even know your transmission is overheating as the Tundra does not have a transmission pan temperature gauge. If you have seen a warning on your dash displaying “High Transmission Fluid Temp”, this means the ATF in the transmission pan has reached 302° F (operating temperature of Toyota ATF WS is 68-221° F). Although you may not have seen this warning before, you could still be running well above the max operating temperature of 221° F without knowing.

Once the oil cooler kit is installed, expect ATF pan temperatures to be between 185-215° F depending on ambient temperatures and your load (with thermostat not pinned open). Toyota specifies the operating temperature of Toyota ATF WS to be between 68-221° F.
