Checking Automatic Transmission Fluid Level and Condition.

Drain and Overfill Plug Locations

The following is an extract from the Holden Jackaroo Workshop Manual and is applicable for those vehicles without automatic transmission dipsticks.
Checking fluid level and condition (colour and odour) at regular intervals will provide early diagnosis information about the transmission. This information may be used to correct a condition that, if not detected early, could result in major transmission repairs.

IMPORTANT. When new, automatic transmission fluid (ATF) is red in colour. As the vehicle is driven, the transmission fluid will begin to look darker in colour. The colour may eventually appear light brown. A dark brown colour with a burnt odour may indicate excessive fluid deterioration and signal a need for fluid change.

FLUID LEVEL.
When adding or changing ATF use only DEXRON-III. Check owner's manual for maintenance information and servicing interval.

CAUTION: DO NOT OVERFILL.
Overfilling will cause foaming, loss of fluid, abnormal shifting and possible damage to the transmission.

  1. Park the vehicle on level ground and apply the parking brake firmly.
  2. Check the fluid level with the engine running at idle.

    NOTE: Be sure that the ATF is below 30 degrees Centigrade.

  3. Move the selector lever through all gear ranges.
  4. Move the selector lever to "Park".
  5. Let the engine idle for 3 minutes and open the overfill screw (1) in diagram.
  6. Add/release ATF until it flows out over the overfill screw opening.
  7. Let the engine idle until a fluid temperature between 32 and 57 degrees Centigrade is reached , then close the overfill screw (1).

Torque: 38 Nm (3.9 kg-m 28 lb ft)

Note: To prevent fluid leaks, the overfill screw (1) and oil drain screw (2) gaskets must be replaced each time these screws are removed.

Part Nos.
Screw: 8-96015-481-0
Gasket: 8-01638-257-0

CAUTION: Do not open overfill screw with engine stopped.

DO NOT CHECK FLUID LEVEL UNDER THESE CONDITIONS;
Immediately after driving at sustained high speeds,
in heavy traffic during hot weather,
if the vehicle is towing a trailer.
If the vehicle has been operated under these conditions, shut the engine off and allow the vehicle to "cool" for 30 minutes. After cool down period, restart the vehicle and continue from step 2 above.
