DESCRIPTION
The
Muncie
4-speed
transmission is used with all
eight
cylinder
engines
when a
4-speed
transmission
is specified. It can be distinguished from the Saginaw
4-speed
in that the reverse lever on the Muncie is
mounted in the
extension
housing where on the Sagi-
naw it is mounted in the side cover.
PERIODIC
SERVICE
TRANSMISSION
No periodic service of the transmission is re-
quired
except
checking for leaks and proper lubricant
level every 60 days.
If
there is
evidence
of leakage, the leak should be
corrected and lubricant added, if
needed.
Refill
capacity is 2 1/2 pints.
Remove filler plug at side of case and add
SAE
90
multi-purpose gear lubricant.
Lubricant
level should
be approximately level with
bottom
of filler plug
hole.
Install
plug.
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.
