DESCRIPTION AND OPERATION
Transmission Cooling —
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 .

DESCRIPTION AND OPERATION
External Controls
The transmission shift cable transfers the transmission operating mode from the gearshift lever to the
automatic transmission (7003). The indicated position of the transmission floor mounted selector lever
is transferred to the transmission through the cable and down to the manual control lever on the
transmission.
Shift Interlock System
The brake/shift interlock mechanism is used on vehicles equipped with an automatic transmission.
This system is used to prevent shifting from PARK unless the brake pedal is depressed. The
brake/shift interlock system consists of an actuator attached to the key interlock assembly and
necessary wiring. The shift lock actuator is energized when the ignition switch is turned to the run
position, locking the floor mounted transmission range selector lever in the PARK position. When the
brake pedal is depressed, the shift lock actuator is deactivated and the floor mounted transmission
range selector lever can be moved out of the PARK position.
Transmission Control Switch (TCS)
The transmission control switch (TCS) is a momentary contact switch that is located on the floor
mounted transmission range selector lever. Pushing the TCS will either disengage or engage the
overdrive function of the automatic transmission. If the OVERDRIVE is disengaged, the word O/D OFF
will illuminate on the instrument cluster.
