GENERAL PROCEDURES
Transmission Fluid Drain and Refill
Draining
CAUTION: Always refer to the instructions supplied with the flush and fill machine.
NOTE: Draining fluid from the transmission by removing only the fluid pan is acceptable for vehicles
that do not have a torque converter drain plug, for normal or severe duty fluid maintenance.
NOTE: A new procedure for draining and adding transmission fluid using a suitable transmission flush
and fill machine has been added. The following procedure has different methods for draining and
refilling the listed vehicles:
zAll vehicles using a suitable flush and fill machine.
z Vehicles equipped with a torque converter drain plug.
z Vehicles without a torque converter drain plug.
Use the method that is applicable to your vehicle.
All vehicles using a suitable flush and fill machine 1. With the vehicle in NEUTRAL, position on a hoist. For additional information, refer to Section 100 - 02 .
2. Use a suitable flush and fill machine to change the fluid.
3. When connecting the flush and fill machine, connect the machine to the fluid cooler tube after the fluid cooler on the cooler return line. This will help remove any foreign material trapped in
the fluid coolers. Refill SECTION 307-

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.

VEHICLE REPAIR
Fluid Pan, Gasket and Filter
1. Normal maintenance requires periodic automatic transmission fluid changes. If a major repair, such as a clutch, band, bearing, etc., is required, the automatic transmission will also have to be
removed for repair. At this time, the torque converter, transmission cooler and tubes must be
thoroughly flushed to remove any dirt. The transmission fluid needs to be changed if evidence
of fluid contamination is found. When used under continuous or severe conditions, the
transmission and torque converter should be drained and refilled with fluid as specified.
2. CAUTION: Do not use any supplemental transmission fluid additives or cleaning
agents. The use of these products could cause internal transmission components to fail;
this will effect the operation of the transmission.
CAUTION: Use of a fluid other than specified could result in transmission failure.
Refer to the vehicle certification label affixed to the LH front door lock face panel or door pillar
for the transmission code.
3. When filling a dry transmission and torque converter, refer to General Specifications chart in this section for capacity. Check the fluid level.
Removal
1. Disconnect the battery ground cable. For additional information, refer to Section 414 - 01 .
2. Raise and support the vehicle. For additional information, refer to Section 100 - 02 .
3. Place a drain pan under the transmission fluid pan.
4. Drain transmission fluid. zLoosen the transmission fluid pan bolts and allow fluid to drain. After fluid is drained
remove the bolts.
