    • Fill the transmission with the correct specification of fluid. Fill oil through the overflow hole until the level inside is high enough that oil flows back out of the same hole.

      Refer to: SPECIFICATIONS 

    • Install the fluid level plug finger tight at this stage.
    • Remove the container from under the transmission to avoid damage.
11. • Lower the vehicle.
    • Start the engine, and allow to idle.

    • Raise the vehicle.
    • Place the container under the transmission to catch the overflow oil.
    • Remove the transmission fluid level plug.
    • Fill oil through the overflow hole until the level inside is high enough that oil starts to flow back out of the same hole.
13. Raise the engine speed to 2000 rpm and hold for 30 seconds. Then return to idle speed.
14. Fill oil through the overflow hole until the level inside is high enough that oil starts to flow back out of the same hole.
15. NOTE: Vehicles without thermostat

    Install the oil filler plug and proceed to Step 17.

    Special Tool(s): 307-452 

    Torque  : 20 Nm 

17. • Carry out a road test to open the thermostat and allow the transmission fluid to fill the transmission cooling system.
    • Proceed to the next step.
18. NOTE: The following steps must be observed before starting the transmission fluid level check.
    • Make sure that the EPB is applied.
    • The vehicle must be on a horizontal ramp.
    • Make sure the TCS is in the P position.
19. CAUTION: Using Land Rover approved diagnostic equipment, make sure the transmission temperature is between is 30°C (85°F) and 50°C (122°F) before starting the fluid level check.
    • Connect Land Rover approved diagnostic equipment to the vehicle.
    • Start the engine and allow to idle.
    • Switch off the air conditioning (A/C) system and other electrical components.
20. • 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.
21. • Apply and hold the brake pedal.
    • Select reverse gear and wait for 10 seconds.
    • Select drive, then manual 1st gear and wait for 10 seconds.
    • Select 2nd gear and wait for 10 seconds.
    • Select P on the TCS.
22. Raise the engine speed to 2000 rpm and hold for 30 seconds. Then return to idle speed.
23. NOTE: After completing the preparation, proceed to the transmission fluid level check.
    • If the transmission oil temperature is lower than 30°C (86°F). Allow the transmission to warm up above 30°C (86°F) with the engine idling in the P position, then proceed with the transmission fluid level check.
    • If the transmission oil temperature is above 50°C (122°F), switch off the engine and allow the transmission to cool down, then restart the fluid level check.
24. CAUTION: Only continue with the fluid level check if the transmission temperature is between 30°C (86°C) 50°C (122°).
    • Start the engine, if not already idling.
    • Maintain the engine idle speed.
25. • Raise the vehicle.

    • Remove the oil filler plug, do not discard.
    • If fluid flows out, proceed to Step  28.
    • If fluid does not flow out, proceed to Step 27.
    • Special Tool(s): 307-452 
27. CAUTION: Use transmission fluid meeting Land Rover specification.

    • To make sure the transmission fill plug is tightened to the correct specification. Using the special tool and torque wrench the following calculation steps must be followed.
    • Step 1. Multiply 35 Nm by the effective length of the torque wrench (1).
    • Step 2. Add the effective length of the special tool (2) to the effective length of the torque wrench (1).
    • Step 3. Divide the total of step 1 by the total of step 2.
    • Step 4. Set the torque wrench to the figure arrived at in step 3.
    • Tighten the transmission fluid fill plug to the torque given by the calculation.
31. CAUTION: Clean the area around the filler plug, wipe away any excess fluid.

    Remove the container.
