Fluid Level Check
CAUTION: The vehicle should not be driven if the fluid level indicator shows the fluid below the DO NOT DRIVE mark or internal failure could
result.
NOTE: If the vehicle has been operated for an extended period, at high highway speeds, in city traffic, during hot weather, or while pulling a trailer,
the fluid needs to cool down to obtain an accurate reading.
NOTE: The fluid level reading on the indicator will differ from operating and ambient temperatures. The correct reading should be within the normal
operating temperature range.
Under normal circumstances the fluid level should be checked during normal maintenance. If the transmission starts to slip, shifts slowly, or shows
signs of fluid leaking, the fluid level should be checked.
1. With the transmission in P (PARK), the engine at idle, foot pressed on the brake, move the range selector lever through each gear and allow
engagement of each gear. Place the transmission range selector lever in the P position.
2. Wipe the fluid level indicator cap and remove the indicator.
3. Wipe the indicator with a clean cloth.
4. Install the indicator back in the filler tube until it is fully seated, then remove the indicator. The fluid level should be within the normal operating
temperature range.
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 failure. If an overfill reading is indicated, drain and refill the
transmission.
Low Fluid Level
A low fluid level could result in poor transmission engagement, slipping, or failure. 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 failure.
If fluid needs to be added, add fluid in 0.25L (1/2 pint) increments through the filler tube. Do not overfill the fluid. For fluid type, refer to the
