Transmission Fluid Drain and Refill
Draining
CAUTION: Use only clean transmission fluid specified for this transmission. 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 affect the operation of the transmission.
CAUTION: Always refer to the instructions supplied with the flush and fill machine.
NOTE: Draining transmission fluid from the transmission by removing only the transmission fluid pan is acceptable for vehicles that do not have a torque converter drain plug, for normal or severe duty transmission 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:
^ All vehicles using a suitable flush and fill machine.
^ Vehicles equipped with a torque converter drain plug.
^ 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 it on a hoist.
2. Use a suitable flush and fill machine to change the transmission 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 tube. This will help remove any foreign material trapped in the fluid coolers.
Refill
4. Use only clean transmission fluid.
5. Once the transmission 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 transmission fluid is needed, add transmission fluid in increments of 0.24L (0.5 pt) until the correct level is achieved (transmission fluid should be in the cross-hatched area of the transmission fluid level indicator).
Draining
Vehicles without a torque converter drain plug
1. With the vehicle in NEUTRAL, position it on a hoist.
2. Loosen the transmission fluid pan bolts and allow the transmission fluid to drain.
3. After the transmission fluid has drained, remove the transmission fluid pan.
4. Do not remove the transmission fluid filter. It is not necessary to change the transmission fluid filter during a normal maintenance transmission fluid change.
5. Clean and inspect the transmission fluid pan, transmission fluid pan gasket and magnet.
6. Thoroughly flush the cooler tubes.
Refill
7. Position the magnet into the transmission fluid pan.
8. NOTE: The transmission fluid pan gasket is reusable. Clean and inspect for damage. If not damaged, the transmission fluid pan gasket should be reused.
Install the transmission fluid pan and gasket.
1) Position the transmission fluid pan with the gasket in place.
2) Install the bolts.
^ Tighten to 14 Nm (10 lb-ft).
9. 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.
^ Add 4.7L (5 qt) of clean transmission fluid to the transmission through the transmission fluid filler tube.
10. Start the engine. Move the selector lever through all the gear ranges, checking for engagements.
11. 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 transmission fluid is needed, add transmission fluid in increments of 0.24L (0.5 pt) until the correct level is achieved (transmission fluid should be in the cross-hatched area of the transmission fluid level indicator).
