Transmission Oil Check / Top Up

Transmission Oil Check / Top Up

The ZF 6 HP26 automatic transmission is ‘filled for life’ at manufacturer and will not normally require any servicing.

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

⚠ Warning ⚠
Observe all transmission oil manufacturers safety instructions when draining and refilling the automatic transmission.

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

• The car is on a horizontal ramp
• 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
• The transmission sump temperature is between 30°C-50°C (86°F-122°F) when opening the filling plug and whilst checking oil level
• Positions Reverse and Drive have been engaged for a minimum of 3 seconds with rear wheels braked before a setting is carried out
• The TCM is not in limp home mode

1. Remove the rear under tray.

⚠ Warning ⚠
While the engine is running ensure that an exhaust extractor system is attached to the exhaust system.

⚠ Warning ⚠
Do not breathe exhaust fumes. Exhaust fumes contain carbon monoxide. Carbon monoxide is a dangerous gas, which is colourless and odourless and can cause unconsciousness and may be fatal.

2. Remove the RH exhaust pipe.
3. Run the engine between 600 and 750 rpm.
4. Place a suitable container to hold any oil that may come from the opening.
5. Remove the fill plug (rear RH side of the transmission) immediately after starting up the engine.

6. Top up oil level with transmission oil (Refer to ‘Specifications’, page 7-1-3), until transmission oil drains out of the bore. Stop topping up.
7. Wait until the out coming transmission oil starts dribbling, but at least 1(one) minute or the oil reached 50°C (122°F).
8. Install the fill plug and make sure that the sump temperature has not exceeded 50°C (122°F).
9. Install the RH exhaust pipe. Install the rear under tray.
10. To ensure that the gearbox and coolant system has been fully charged, complete a test drive. Ensure that the transmission cooling thermostat fully opens (75°C (167°F)).
11. Check the transmission oil level.

Differential Oil Check / Top Up

The Graziano differential is ‘filled for life’ at manufacturer and will not normally require any servicing.

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

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

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

• The car is on a horizontal ramp
• 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
• Ensure the vehicle has run a short distance to ensure that the differential cooling system has been completely filled

1. Remove the rear under tray.
2. Place a suitable container to hold any differential oil that may come from the opening.
3. Remove the fill plug.

With the fill plug removed the differential oil should just ‘dribble’ from the opening in the side of the differential.

4. If required fill the differential with the specified oil until oil ‘dribbles from the hole (Refer to ‘Specifications’, page 7-1-3).
5. Install the rear under tray.
