DESCRIPTION
The Saginaw 4-speed transmission is used on all
Tempests and Firebirds when a 4-speed is ordered
with the 6-cyl. engine. It has all forward gears
synchronized with a constant mesh reverse idler.
Since the Saginaw 4-speed is very similar to the
Saginaw 3-speed transmission, many operation pro-
cedures are the same. In such cases, a note will be
made to refer to the Three Speed Saginaw Manual
Transmission Section, Section 7B.
