DESCRIPTION
The Saginaw three speed manual transmission is

with the 400 cu. in. V-8 engine.
Gear ratios for the 6-cylinder engines are 2.85:1
in first, 1.68:1 in second, 1:00:1 in high and 2.95:1
in reverse. The 8-cylinder engine gear ratios are
2.54:1 in first, 1.50:1 in second, 1.00:1 in high and
2.63:1in reverse.
PERIODIC SERVICE
TRANSMISSION
No periodic service of the transmission is re-
quired except checking for leaks and proper lubri-
cation level every 6000 miles.
If there is evidence of leakage, leak should be
corrected and lubrication added as needed. Refill
capacity is 3-1/2 pints.
Use SAE 90 multi-purpose Gear Lubricant. No
special additive to this lubrication is required or
recommended.
SHIFT CONTROL
No periodic service of the shift control is re-
quired. Certain parts are lubricated on assembly
and require further lubrication only when parts be-
come dry and sticky.
