CAUTION:

Using Land Rover approved diagnostic equipment, make sure the transmission temperature is between is 35ºC (95ºF) and 45ºC (113ºF) before starting the fluid level check.

The following steps must be observed before starting the transmission fluid level check.

  • Connect Land Rover approved diagnostic equipment to vehicle

General Equipment: Land Rover diagnostic equipment

  • Start the engine and allow to idle.
  • Switch off the air conditioning (A/C) system and other electrical components.
  • Make sure that the transmission is not in the default mode, if this is the case, stop and correct the cause first and then restart the fluid level check.

CAUTION:

Make sure the hydraulic control system is filled with oil.

  • Apply and hold the brake pedal.
  • Select reverse gear and wait for 10 seconds.

  • Select Park (P) on the TCS.

CAUTION:

Make sure the park position is selected before carrying out the transmission hydraulic system fill process.

NOTE:

Make sure the transmission hydraulic system is completely filled with oil.

  • Raise the engine speed to 2000 rpm and hold for 30 seconds.

    Then return to idle speed.

NOTE:

After completing the preparation, proceed to the actual transmission fluid level check.

  • If the transmission oil temperature is lower than 35ºC (95ºF).

    Allow the transmission to warm up above 35ºC (95ºF) with the engine idling in the P position, then proceed with the transmission fluid level check.

  • If the transmission oil temperature is above 45ºC (113ºF), switch off the engine and allow the transmission to cool down, then restart the fluid level check.

CAUTION:

Only continue with the fluid level check if the transmission temperature is between 35ºC (95ºF) 45ºC (113ºF).

  • Start the engine, if not already idling.
  • Maintain the engine idle speed.

Remove the engine underhield.

Refer to: Engine Undershield (501-02 Front End Body Panels, Removal and Installation).

CAUTION:

Transmission fluid temperature must not exceed 45ºc (113ºF).

NOTE:

With the engine running a small amount of automatic transmission fluid should trickle out of the transmission fluid level plug hole.

Transmission Fluid Level Check (G1660817) General Procedures

  1. If fluid flows out, proceed to step 13.
  2. If fluid does not flow out, proceed to step 12.

Transmission Fluid Level Check (G1660817) General Procedures

  1. If the transmission fluid does not come out of the transmission fluid level plug hole the transmission fluid level is insufficient. If this is the case add the transmission fluid in 100 millilitre units into the transmission fluid level plug hole using a suitable syringe.

General Equipment: Oil syringe

  1. Allow the transmission fluid to drain from the transmission fluid level plug hole until the flow almost stops to a trickle.

Transmission Fluid Level Check (G1660817) General Procedures

Torque: 35 Nm

Switch off the engine.

Remove the container.

Install the engine undershield.
