The gearbox clunks in 1st or
reverse gear only when
cold:
- vehicle stationary,
- engine running.

The mechanism is drained during the major service.
The oil level must be checked every 10000 miles (15 000 km) in case there is a slight oil leak.
The final drive is never drained ; it is filled for life.
The strainer is no longer replaced (NT 2261A).
Only the level may change due to a slight leak.
Oil capacity
NOTE :if the automatic transmission is replaced, only check the oil level since the transmission is supplied by
the Parts Department full of oil.

Fault warning light
MESSAGE FROM THE ELECTRONIC FAULT
WARNING LIGHT
Normal operation :
• The warning light is not illuminated during
normal operation whether the vehicle is being
started, engine running or when the vehicle is
stationary.
Presence of a fault :
• Vehicle stopped, engine running, or when
driving, warning light permanently illuminated
• Vehicle moving, warning light illuminates and
extinguishes without action at the ignition key.
• Vehicle moving, warning light illuminates
briefly.Oil temperature < - 20 °C or > + 140 °C
• Vehicle moving or stationary, warning light
flashes at a rate of approximately 1 flash per
second, in this case, reduce the performance
requirement by moderating acceleration.
