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 Item Description
1 Fluid level at room temperature 10°-
35°C (50°-95°F) 2 Fluid level at operating temperature 66°-
77°C (150°-170°F) 3 Do not drive mark Klj . 2 ba
