Adding Fluid
CAUTION: The use of any other type of transmission fluid than specified could result in transmission malfunction and/or damage.
If fluid needs to be added, add fluid in 0.25 Liters (1/2 pint) increments through the filler tube. Do not overfill the fluid.
Fluid Condition Check
1. Cheek the fluid level.
2. Observe the color and the odor. The color under normal circumstances should be dark reddish, not brown or black or have a burnt odor.
3. Hold the fluid level indicator over a white facial tissue and allow the fluid to drop onto the facial tissue and examine the stain.
4. If evidence of solid material is found, the transmission fluid pan should be removed for further inspection.
5. If the stain is a foamy pink color, this may indicate coolant in the transmission. The engine cooling system should also be inspected at this time.
6. If fluid contamination or transmission failure is confirmed by the sediment in the bottom of the fluid pan, the transmission must be disassembled
and completely cleaned. This includes the torque converter, coolers, cooler lines and remote filter.
7. Carry out diagnostic checks and adjustments. Refer to Diagnosis By Symptom. See: Powertrain Management/Transmission Control

Draining
CAUTION: Always refer to the instructions supplied with the flush and fill machine.
1. With the vehicle in PARK, 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 tube after the fluid cooler on the cooler return line. This will
help remove any foreign material trapped in the fluid coolers.
Refill
1. Once the fluid exchange has been completed, disconnect the flush and fill machine. Reconnect any disconnected fluid cooler tubes.
2. 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 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).
