Fluid - A/T: Testing and Inspection
Determining Fluid Level and Condition
High Fluid Level
A fluid level that is too high may cause the fluid to become aerated due to the churning action of the rotating internal parts. This will cause erratic control
pressure, foaming, loss of fluid from the vent tube and possible transmission malfunction and/or damage. If an overfill reading is indicated, refer to the
transmission fluid drain and refill procedure.
Low Fluid Level
A low fluid level could result in poor transmission engagement, slipping, malfunction and/or damage. This could 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 could result in transmission malfunction and/or damage.
Before adding fluid be sure that the correct type is being used: refer to the fluid level indicator and/or the owners manual.
If fluid needs to be added, add fluid in 0.25L (1/2 pint) increments through the filler tube. Do not overfill the fluid.
Fluid Condition Check
1. Check the fluid level.
2. Observe the color and the odor. The color under normal circumstances should be dark reddish, not brown or black.
3. Hold the fluid level indicator over a white facial tissue and allow the fluid to drip onto the facial tissue and examine the stain.
4. If evidence of solid material is found, the oil 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 oil pan, the transmission must be disassembled and
completely cleaned. This includes the torque converter and cooler lines.
7. Perform diagnostic checks and adjustments.
