Transmission Cooler: Description and Operation

Figure 9-Transmission Oil Cooler:

The transmission oil cooler circuit consists of a series connected internal cooler mounted inside the left radiator tank and an auxiliary external oil cooler mounted to the front of the air conditioning condenser.

Steel tubes and rubber lines supply the oil from the transmission to the internal oil cooler and return the oil to the transmission from the auxiliary external oil cooler.

Use only approved transmission oil cooler hoses. Since these hoses are molded to fit space available, molded hoses are required. The steel tubes must be flared to ensure sealing of the hose. Torque oil cooler hose clamps to 2.5 Nm (22 inch lbs.).
