DESCRIPTION
The Saginaw 4-speed transmission is used on Firebirds
when a Cspeed is ordered with the 6-cyl. engine. It has
all forward gears synchronized with a constant mesh
reverse idler.
Since the Saginaw Cspeed is very similar to the
Saginaw 3-speed transmission, many operation proce-
dures are the same. In such cases, a note will be made
to refer to the Three Speed Saginaw Manual Tranimis-
sion Section, Section 7B.
For all models, the steering column lock requires that
the transmission be in "Reverse" gear before the
ignition key may be removed. Also, the clutch safety
switch will not permit engine cranking unless the
clutch pedal is depressed far enough to completely
disengage the clutch.
