WARNING: Make sure that care is exercised near rotating parts. Failure to follow this

instruction may result in personal injury.

With the engine running, remove the transmission fluid filler plug using the special tool.

•

Remove and discard the sealing washer.

9. NOTE:

Use transmission fluid meeting Jaguar specification.

If the transmission fluid does not come out of the transmission fluid filler plug hole the transmission

fluid level is insufficient. If this is the case add the transmission fluid in 0.5 liter units into the

transmission fluid filler plug hole until fluid comes out.

10. NOTE:

Make sure the transmission fluid temperature does not exceed 50°C (122°F). If the transmission

fluid temperature does exceed 50°C (122°F) stop the transmission fluid level check and allow the

transmission fluid to cool until the temperature is below 30°C (86°F).

Allow the transmission fluid to drain from the transmission fluid filler plug hole until the flow almost

stops.

11. Using the special tool, install the transmission fluid filler plug.

•

special tool and a 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.
