Fluid - A/T: Service and Repair
Check Fluid Level and Condition
Check Fluid Level and Condition
CAUTION: The vehicle should not be driven if the fluid level is low or internal failure can result.
NOTE: If the vehicle has been operated for an extended period of time at highway speeds, city traffic, hot weather, or pulling a trailer, the fluid needs
to cool down 30 minutes to obtain an accurate reading.
This vehicle is not equipped with a fluid level indicator. An incorrect level may affect the transmission operation and could result in transmission
damage. To correctly check and add fluid to the transmission, refer to Transmission Fluid Level Check.
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 damage. Refer to Transmission Fluid Level Check to correct a
possible overfill condition.
Low Fluid Level
A low fluid level can result in poor transmission engagement, slipping or damage. This can also indicate a leak in one of the transmission seals or
gaskets.
Adding Fluid
CAUTION: The use of any type of transmission fluid other than specified could result in transmission damage.
If fluid needs to be added, add fluid in 0.25 L (1/2 pint) increments through the fluid level plug in the bottom of the pan. Do not overfill the fluid.
Fluid Condition Check
1. Check the fluid level.
2. Observe the color and the odor of the fluid. Under normal circumstances the color should be dark reddish, not brown or black.
3. Allow the fluid to drip onto a 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 fluid contamination or transmission failure is confirmed by the sediment in the bottom of the transmission fluid pan, the transmission must be
disassembled and completely cleaned.
6. Carry out diagnostic checks and adjustments. Refer to Diagnosis By Symptom. See: Powertrain Management/Transmission Control
Systems/Testing and Inspection/Symptom Related Diagnostic Procedures
