Maintenance

Oil Check and Top-up

The transaxle is filled for life and would only require checking and topping-up in the event of a oil leak or strip down of the transaxle cooling system.

In the event of a oil leak from the transaxle cooling system, the leak must be repaired and then the transaxle oil may be replenished as follows:

⚠ Warning ⚠
Observe all transaxle oil manufacturers safety instructions when draining and refilling the manual transaxle.

Before doing any work to the transaxle oil level setting make sure that:

  • The car is on a horizontal ramp
  • The engine is not running
  • The rear wheels are standing still for a minimum of 2 minutes before starting the oil level check and during the process, e.g. by applying the hand brake
  1. Place a suitable container to hold any transaxle oil that may come from the opening.
  2. Remove the fill plug.
    With the fill plug removed transaxle oil should just ‘dribble’ from the opening.
  3. If required fill the transaxle with the specified oil until oil ‘dribbles from the hole (Refer to ‘Specifications’, page 7-3-2).

Drain / Fill

  1. Place a suitable container to hold the transaxle oil.
  2. Remove the drain plug. Allow the oil to drain.
  3. Disconnect the oil cooling pipes and allow the oil in the cooling system to drain in to the container.
  4. Complete with a new sealing washer, install the drain plug. Torque plug to 49 Nm.
  5. Connect the oil cooling system pipes.
  6. Fill the transaxle with the correct oil.
  7. Run the vehicle a short distance to ensure that the transaxle cooling system has been completely filled. Check / Top-up.
