TRANSMISSION
Description.
The transmission and differential, with final drive
gears
I
are incorporated in a single case.
Transmission provides four forward gears (all
synchromeshed) and reverse.
The fourth gear is
an overdrive.
Helical gears of all forward speeds are syn-
chromeshed.
Synchromesh rings are of the sliding type.
Transmission is controlled manually through a
gearshift lever on floor tunnel, between front seats.
The hypoid final drive set has a gear ratio of
4.625 to 1
(8/37).
Power drive to rear wheels is transmitted by
means of two axle shafts. which are connected to
the differential unit through slip joints and to axle
shafts through flexible joints.
