In certain cases the ,au.tomatic gearbox is connecte·d
to an 'oil cooler. This is housed in th'e boHom tank of
the engine ,radiator and is connected as shown in Fig.

Ot,he'r, later model, gearboxes can also be fitted
with an oil
cooler.
On ,this occasion the engine radia
-
tor must be changed. The connecting pipe (2, Fig
.

is then removed and the oil cooler eonnected to the
nipples
