4. Use only clean automatic transmission fluid.
5. Once the fluid exchange has been completed, disconnect the flush and fill machine. Reconnect
any disconnected fluid cooler tubes.
6. With the engine running and the transmission at normal operating temperature 66- 77°C (150-
170°F), check and adjust the transmission fluid level, and check for any leaks. If fluid is needed,
add fluid in increments of 0.24- liter (0.5-pint) until the correct level is achieved (fluid should be in
the cross- hatched area of the fluid level indicator).
Draining
Vehicles equipped with a torque converter drain plug 1. With the vehicle in NEUTRAL, position on a hoist. For additional information, refer to Section 100 - 02 .
2. Loosen the transmission fluid pan bolts and allow the fluid to drain.
3. After the fluid has drained, remove the transmission fluid pan.
4. Do not remove the fluid filter. It is not necessary to change the fluid filter during a normal maintenance fluid change.
5. Remove the torque converter drain plug cover. Klj . 2 ba

NOTE: The fluid pan gasket is reusable, clean and inspect for damage. If not damaged, the
gasket should be reused.
Install the fluid pan and gasket. 1. Position the fluid pan with the gasket in place.
2. Install the bolts.
13. CAUTION: The use of any other transmission fluid can result in the transmission
failing to operate in a normal manner or transmission failure.
Fill the transmission.
zAdd 4.7 liters (5 qts) of clean automatic transmission fluid to the transmission through the
fluid filler tube.

INSTALLATION
Transmission
1. CAUTION: During this move, to avoid damage, do not allow the transmission to get
into a nose- down position as this will cause the torque converter to move forward and
disengage from the pump gear. The converter housing is piloted into position by dowels
in the rear of the engine block. The torque converter must rest squarely against the
flexplate. This indicates that the converter pilot is not binding in the engine crankshaft.
Position and secure the transmission on the high- lift transmission jack.
2. CAUTION: Make sure the torque converter is fully seated in the transmission before
positioning the transmission to the engine.
Using the special tool, install the transmission to the engine.
zAlign the orange balancing marks on the converter stud and the flexplate bolt hole. 3. Reconnect the harness. SECTION 307-

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 .
