cause erratic control pressure, foaming, loss of fluid from the vent tube and possible transmission failure.
If an overfill reading is indicated, drain and refill the transmission.
Low Fluid Level
A low fluid level can result in poor transmission engagement, slipping or failure. This may also indicate a leak in one of the transmission seals or
gaskets.
Adding Fluid
CAUTION: The use of any other type of transmission fluid than specified can result in transmission failure.
If fluid must be added, add fluid in 0.5 liter (1/2 quart)increments through the fluid fill plug. Do not overfill the fluid. For fluid type, refer to the
specification chart.
Fluid Condition Check
1. Check the fluid level.
2. Remove the fluid fill plug and allow the fluid to drip onto a facial tissue and examine the stain.
3. NOTE: The transmission fluid could be 2 different colors. The factory fill fluid is clear. The replacement fluid is red.
Observe the color and the odor. The color under normal circumstances should be dark reddish or clear, not black or have a burnt odor.
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 and fluid cooler tubes. A new oil-to-air cooler must be installed.
