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 to try cool your transmission fluid. It is not effective and many owners while towing or off-roaring have received warnings on their dash for high ATF temperatures (warning comes when the transmission pan reaches 302° F).

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.
