CLUTCHES AND TRANSMISSIONS 7-46
L I. - LI Range can be selected at any vehicle speed, and
the transmission will shift to second gear and re­
main in second until vehicle speed is reduced to
approximately 40 MPH, depending on axle ratio.
LI Range position prevents the transmission from
shifting out of first gear.
It is very important that any communication concerning
the Turbo Hydra-Matic always contain the transmission
serial number and that all transmission parts returned to
Chevrolet Motor Division always be tagged with the
transmission serial number.
MAINTENANCE AND ADJUSTMENTS
TRANSMISSION FLUID
Transmission fluid level should be checked with trans­
mission warm and selector lever in "P " Park position,
every time engine oil level is checked or as specified in
Section 0 when engine oil is changed.
CAUTION: Since the Turbo Hydra-Matic
transmission is very sensitive to oil level, spe­
cial precautions should be taken when checking
the oil level, to insure against an overfill.
Transmission fluid should be changed as specified in
Section 0.
FLUID LEVEL INDICATOR
The fluid level indicator is located in the filler pipe at
the right rear corner of the engine. To bring the fluid
level from the add mark to the full mark add
1
pint.
Fluid level should be to the full mark with transmis­
sion at normal operating temperature. With cold fluid
the level should be at the add mark or slightly below.
SHIFT CONTROL LINKAGE ADJUSTMENT
Adjust linkage as described below:
COLUMN SHIFT
1. The shift tube and lever assembly must be free in
the mast jacket. See Section 9 for alignment of
steering column assembly if necessary.
2. To check for proper shift linkage adjustment, lift the
transmission selector lever towards the steering
wheel. Allow the selector lever to be positioned in
drive (D) by the transmission detent.
NOTE: Do_ not use the indicator pointer as a
reference to positon the selector lever. When
performing linkage adjustment, pointer is ad­
justed last.
3. Release the selector lever. The lever should be in­
hibited from engaging low range unless the lever is
lifted.
4. Lift the selector lever towards the steering wheel,
and allow the lever to be positioned in neutral (N)
by the transmission detent.
5. Release the selector lever. The lever should now be
inhibited from engaging reverse range unless the
lever is lifted.
6
. A properly adjusted linkage will prevent the selector
from moving beyond both the neutral detent, and the
drive detent unless the lever is lifted to pass over
the mechanical stop in the steering column. See
schematic diagram.
7. In the event that an adjustment is required, place the
selector lever in drive (D) position as determined
by the transmission detent. See Steps 2 and 3.
