Fluid - A/T: Testing and Inspection



Transmission oil level

- Ensure that the transmission is at normal operating temperature, e.g. by conducting a 20 mile road test. If starting from cold: check for presence of oil on dipstick at idle in 'P' Park to the 'Cold' fill mark before setting off.

- Check that the vehicle is on level ground.

- Firmly apply the parking and foot brakes and run the engine at idle speed.

- To ensure that the system is primed, slowly move the selector lever through all the gear positions.

- With the engine still running, engage 'P' Park, withdraw the dipstick and wipe with a lint free cloth.

- Replace the dipstick slowly and withdraw it noting the level.

- Top up as required and recheck the level.

Note: The oil level can only be accurately checked when at normal temperature - approximately 20 miles at moderate speeds.
