INTRODUCTION

The transmission fluid cooler is a separate cooling unit located behind the engine cooling radiator. The transmission is connected to the fluid cooler via flexible hoses and metal pipes.

The transmission cooler is a dedicated fluid cooler which is connected into the engine cooling system circuit. The transmission fluid is cooled by the temperature differential between the transmission fluid and the engine coolant flowing through the cooler and also by airflow over cooling fins on the end tank.

Fluid is supplied from the transmission fluid pump into the lower connection of the cooler. After passing through the cooler, the fluid passes out of the upper connection and is returned to transmission fluid pan.
