Integral
This vehicle with an automatic transmission is equipped with an integral transmission fluid cooler. The
cooler is contained inside of the radiator outlet tank and cannot be serviced separately. The cooler
transfers heat from the transmission fluid to the engine coolant.
For transmission fluid cooler flow test, refer to Section 307 - 01 .
For transmmission fluid cooler backflushing and cleaning, refer to Section 307 - 01 .

DIAGNOSIS AND TESTING
Transmission Cooling
Inspection and Verification
WARNING: Never remove the radiator cap under any conditions while the engine is
operating. Failure to follow these instructions could result in personal injury and/or damage to
the cooling system or engine. To avoid having scalding hot coolant or steam blow out of the
radiator, use extreme care when removing the radiator cap from a hot radiator. Wait until the
engine has cooled, then wrap a thick cloth around the radiator cap and turn it slowly to the first
stop. Step back while the pressure is released from the cooling system. When you are certain
all the pressure has been released, press down on the radiator cap (with a cloth), turn and
remove.
The transmission fluid cooler is integral to the radiator (8005). Whenever leaks or damage to the
radiator are found, install an entire new radiator. For additional information, refer to Section 303 - 03A or
Section 303 - 03B .
