DESCRIPTION
The Saghaw three speed manual transmission is used
as the standard eqwpment transmission on all Tem-
pest and Firebird models except those equipped with
the 400 cu. in. V-8 engine.
Gear ratios for the 6-cylinder engines are 2.85:l in
fmt, 1.68:l in second, 1:00:1 in high and 2.951 in
reverse. The &cylinder engine gear ratios are 2.54:l in
fmt, 1.50: 1 in second, 1.00: 1
in high and 2.63: 1 in
reverse.
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.
