1. CAUTION: Always refer to the instructions supplied with the flush and fill machine.
CAUTION: Do not use any supplemental transmission fluid additives or cleaning agents. The use of these products could cause internal
transmission components to fail, affecting the operation of the transmission.
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 and for normal or severe duty fluid maintenance.
A new procedure for draining and adding transmission fluid using a suitable transmission flush and fill machine has been added. The different
methods for draining and refilling the transmission fluid are listed below.
Use the method that is applicable to your vehicle.

All vehicles using a suitable flush and fill machine
Draining
1. With the vehicle in NEUTRAL, position it on a hoist.
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 line after the cooler on the cooler return line. This will help
remove any foreign material trapped in the fluid coolers.
Refill
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 lines.
6. Lower the vehicle.
7. 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 in the
cross-hatched area of the fluid level indicator).
