Manual gearbox
Oil change
To change the gearbox oil, both drain plugs
(A) must be removed by unscrewing. They
are to be found at the front and back of the
gearbox.
Automatic gearbox
Checking oil level
The level of the oil should be checked re­
gularly, even between services.
The level can be seen through the transpa­
rent reservoir, that is mounted on the back
end of the gearbox housing. The fluid level
must be between the max. and min. marks
when at normal operating temperature.
To check the level, the vehicle must be
standing level. The selector must be in posi­
tion Ν and the engine running at tick-over.
The difference between the two marks is ca.
0.2 liter (1/2 pint).
Should oil leakage be visible the next work­
shop should be called in to rectify the fault.
Oil change
When changing the oil, ca. 5.5 liters (1.25
Imp. galls.) are required to fill the gearbox
and torque convertor.
The filter must be renewed at every oil
change, and the level must be up to the
mark underneath the min. mark.
To refill, only use the oils recommended in
the table "Filling quantities".
For fluid changing intervals see the mainten­
ance plan.
If too much oil is added, inadvertently, it
must be removed.
