Check Fluid Level and Condition

Fluid Level Check

CAUTION: The vehicle should not be driven if the fluid level is low or internal failure could result.

NOTE: If the vehicle has been operated for an extended period of time at highway speeds, in city traffic, in hot weather, or pulling a trailer, the fluid must 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 can 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 can 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. If an overfill reading is indicated, refer to Transmission Fluid Level Check.

Low Fluid Level
A low fluid level can result in poor transmission engagement, slipping or damage. It 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 can result in transmission damage.

If fluid must be added, add fluid in 0.25 L (0.5 pint) increments through the fluid pan level check screw opening. Do not overfill the fluid, refer to Transmission Fluid Level Check.

Fluid Condition Check
1. Observe the color and the odor of the fluid. Under normal circumstances, the color should be dark reddish, not brown or black.
2. Allow the fluid to drip onto a facial tissue and examine the stain.
3. If evidence of solid material is found, the transmission fluid pan should be removed for further inspection.
4. 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.
5. Carry out diagnostic checks and adjustments. For additional information, refer to Diagnosis By Symptom. Diagnosis By Symptom - External Controls
