miles).
The oil should be at the level of the filler hole. Top up with
the recommended oil if necessary. The oil in the gearbox should be
changed after every 40 000 km (25 000 miles). In the case of a new
or reconditioned gearbox, the oil should be changed after the first
5 000 km (3 000 miles), on which occasion the gearbox should be
flushed thoroughly with gear oil. The old oil should be drained off
i

The oil level should be checked and the oil changed in the gearbox
with overdrive at the same interval described for a gearbox without
overdrive.
The oil level and oil filler hole is the same for both the overdrive and
the gearbox. When topping up, make sure that the oil runs over into
the overdrive.
When draining off the oil, note that there is a separate drain plug
(
marked "Drain") for the overdrive.
Cleaning the oil strainer
When changing the oil, clean the overdrive oil strainer.
Clean the strainer in petrol or white spirit and blow it dry, preferably
with compressed air. Check that the gasket is not damaged and place
it in position with the steel lining facing inwards. Then fit the three
magnetized washers so that they are held together by magnetic force,
and then the strainer and cover.

The oil level in the rear axle should be checked after every 5 000 km
(3 000 miles). The oil should be up to the level of the filler hole. Top

The oil in the rear axle should be changed after the first 5 000 km
(3 000 miles), and should also be flushed thoroughly with the same type
of oil used for topping up. The used oil should be drained off immediately

8 Automatic transmission BW 35
The oil should not be changed but the oil level should be checked every
5 000 km (3 000 miles). A filler tube housing a graduated dipstick is
to be found under the bonnet just in front of the cowl. The oil level
should be checked with the vehicle on level ground and with the
transmission at normal working temperature. With the engine idling
and the selector in position "P", the level should be between the upper
and lower graduation marks on the dipstick. If topping up is necessary,
use only special oil for automatic transmissions, Type A.
Note. The dipstick should be wiped with a nylon cloth, paper or
chamois leather. Wipers leaving residues on the dipstick must not be
used.
