Respect the safety and cleanliness requirements.
Draining.
IMPERATIVE: Draining of the gearbox must be done with the oil hot (60°C minimum), in order to
ensure that the impurities in suspension in the oil are eliminated.
NOTE:Drainage is only partial, as the torque converter cannot be drained totally.
Raise the vehicle.
Remove:
- The oil level plug (2)by means of the Torx spanner.
- The drain plug (1)using a hexagonalspanner.
NOTE :Around 3 litresof oil should flow out.
Filling.
Fit the drain plug (1)(with a new seal).
Tighten the plug (1)to: 5 ± 1 mdaN.
Remove:
- The air filter housing.
- The oil filler plug (3).
Use tool [1].
