Check Fluid Level and Condition
Check Fluid Level and Condition
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 of time at highway speeds, in city traffic, in 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 depending on 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 regular maintenance. If the transmission starts to slip, shift slowly, or show
signs of leaking, the fluid level should be checked.
Fluid Level Check
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 range selector lever in the (P) PARK 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 malfunction and or damage. If an overfill reading is indicated
refer to Transmission Fluid Drain and Refill.
Low Fluid Level
A fluid level that is too low may cause the fluid to become aerated due to the churning action of the rotating internal parts.
A low fluid level could also result in poor transmission engagement, slipping, malfunction and/or damage. This could indicate a leak in one of the
transmission seals or gaskets.
