Jeep Cherokee Disconnect Transmission Cooler Lines A transmission cooler was an optional feature on the Jeep Cherokee. The transmission cooler consists of a small radiator bolted behind the engine’s radiator and two transmission cooler lines that extend from the second radiator to the transmission.
The lines are a sending and return line. The transmission cooler uses coolant from the engine radiator. If you plan to remove the transmission cooler lines, you will first need to drain the radiator.
