OTHER SERVICE OPERATIONS

Although certain operations, such as oil pan or gasket

replacement, valve body, governor, filler pipe "O" ring,

speedometer drive gear, case extension "0" ring and

rear oil seal, vacuum modulator, and servo cover or

gasket service may be performed from underneath the
vehicle without removing the Powerglide; their service

procedure is covered in the Passenger Overhaul Manual

and is not repeated here. Refer to the- Powerglide Sec-

tion of the Passenger Overhaul Manual for all other

service operations not covered here.

DIAGNOSIS

Proper operation of the Powerglide transmission may

be affected by a number of factors, all of which must be

considered when trouble in the unit is diagnosed.

Proper trouble diagnosis can only be accomplished

when performed in a thorough step by step procedure.

The following procedure has been devised and tested and

is recommended for all trouble diagnosis complaints and

if the service man will follow this checking procedure,

accurate and dependable diagnosis may be accomplished.

This will result in a savings of time, not only to the

service man, but to the customer as well.

WARMING UP TRANSMISSION

Before attempting to check and/or correct any com-

plaints on the Powerglide transmission it is absolutely

essential that the oil level be checked and corrected if

necessary. An oil level which is either too high or too

low can be the cause of a number of abnormal conditions

from excessive noise to slippage in all ranges.

It must be remembered that cold oil will slow up the

action of the hydraulic controls in the transmission. For

this reason a trouble or oil leak diagnosis should not be

attempted until the transmission has been warmed up by

either of the following procedures:

Shop Warm Up

1.
Connect tachometer to engine.

2.
Set parking brake tight and start engine.

3.
Place selector light in
"D"
(drive) range.

4.
Adjust carburetor idle speed adjusting screw to run

engine at approximately 750 rpm and operate in this

manner for two minutes. At the end of two minutes

of operation, the transmission will be sufficiently

warmed up for diagnosis purposes.
NOTE:
At this point, readjust the engine idle

speed to 450-475 rpm in
"D"
range.

Road Warm Up

Drive the car approximately 5 miles with frequent

starts and stops.

NOTE:
At this point, make sure the engine idle

speed is set to 450-475 rpm in
"D"
range.

CHECKING FLUID LEVEL AND CONDITION

After transmission has been warmed up, check the

fluid level with the engine idling, parking brake set and

control lever in "N" (neutral). If the fluid level is low,

add fluid to bring level up to the full mark on gauge rod,

CAUTION: If fluid level is too high, fluid may

be aerated by the planet carrier. Aerated fluid

will cause turbulence in the converter which will

result in lost power, lower stall speed and lower

pressures in control circuits. Lower fluid level

to full mark, then shut off engine to allow air

bubbles to work out of fluid.

When checking oil level, aburned smell and discolora-

tion indicate burned clutches or bands and the transmis-

sion will have to be removed.

MANUAL LINKAGE

Manual linkage adjustment and the associated neutral

safety switch are important from a safety standpoint.

The neutral safety switch should be adjusted so that the

engine will start in the Park and Neutral positions only.

With the selector lever in the Park position, the park-

ing pawl should freely engage and prevent the vehicle

ADJUSTMENTS

STEERING
GEAR

Before any adjustments are made to the steering gear

in an attempt to correct such conditions as shimmy,

loose or hard steering etc., a careful check should be

made of front end alignment, shock absorbers, wheel

balance and tire pressure for possible cause.

Correct adjustment of the steering gear is very im-

portant. Perform adjustments following the sequence

listed below,

1.
Remove pitman arm nut and mark relation of pitman

arm position to sector shaft. Remove pitman arm

with Tool J- 6632 as shown in Figure 2.

2.
Loosen the pitman shaft lash adjuster screw locknut

and turn the adjuster screw a few turns in a counter-

clockwise direction (fig. 3). This removes the load
Fig. 2—Removing Pitman Arm

imposed on the worm bearings by the close meshing

of rack and sector teeth. Turn steering wheel gently

in one direction until stopped by gear, then back away

about one turn.

CAUTION: Do not turn steering wheel hard

against stops when steering relay rod is discon-

nected as damage to ball guides may result.

3.
All except Corvette and telescopic columns:

a. Disconnect steering column harness at chassis

wiring connector plug.

b.
Remove horn cap or ornament and using an inch

pound torque wrench and socket on steering wheel

nut, measure torque required to keep the wheel

in motion.

c. If torque does not lie within limits given in speci-

fications at rear of manual, adjustment is

necessary.

4.
Corvette and telescopic columns:

a. Use Tool J-5178 to measure.pull at rim of wheel

required to keep wheel in motion (fig. 4).

b.
If pull does not lie within limits given in specifi-

cations in rear of manual, adjustment of worm

bearings is necessary.

NOTE:
If vehicle is equipped with a tilt steer-

ing column, it will be necessary to disconnect

the steering coupling to obtain a torque reading

of the steering column. This torque should then

be subtracted from any reading taken on the

gear.

5. To adjust worm bearings, loosen worm bearing ad-

juster locknut and turn worm bearing adjuster shown

in Figure 3 until there is no perceptible end play in

worm. Check pull at steering wheel, readjusting: if

necessary to obtain proper pull. Tighten locknut and

recheck pull. If the gear feels "lumpy" after adjust-

ment of worm bearings, there is probably damage in

the bearings due to severe impact or to improper

adjustment and the gear must be disassembled for

replacement of damaged parts.

6. After proper adjustment of worm is obtained and all

mounting bolts securely tightened, adjust lash ad-

juster screw. First turn the steering wheel gently

from one stop all the way to the other, carefully

counting the total number of turns. Then turn wheel

back exactly half way, to center position. Turn lash

adjuster screw clockwise to take out all lash in gear

teeth, and tighten locknut. Check pull at steering

wheel taking highest reading as wheel is turned

through center position. See specifications in rear of

manual for proper sector lash adjustment. Readjust

if necessary to obtain proper pull.

NOTE:
If maximum specification is exceeded,

turn las£ adjuster screw counterclockwise, then

come up on adjustment by turning the adjuster in

a clockwise motion.

7. Tighten locknut then recheck pull, as it must lie be-

tween specified readings.

8. Reassemble pitman arm to sector shaft, lining up

marks made during disassembly. Refer to torque

specifications at rear of manual for correct torque

value.

9. Install horn cap or ornament and connect steering

column harness at chassis connector.

NOTE:
Chevy.n models are equipped with a

shim at the frame to steering gear mounting

bolts.
Shims may be removed or installed as

required for proper steering gear alignment.

STEERING WHEEL ALIGNMENT AND

HIGH POINT CENTERING

1.
Set front wheels in straight ahead position. This can

be checked by driving vehicle a short distance on a

flat surface to determine steering wheel position at

which vehicle follows a straight path.

2.
With front wheels set straight ahead, check position

of mark on wormshaft designating steering gear high

point. This mark should be at the top side of the shaft

at 12 o'clock position and lined up with the mark in

the coupling lower clamp.

3.
If gear has been moved off high point when setting

wheels in straight ahead position, loosen adjusting

sleeve clamps on both left and right hand tie rods,

then turn both sleeves an equal number of turns in

the same direction to bring gear back on high point.

CAUTION: Turning the sleeves an unequal
number of turns or in differential directions will

disturb the toe-in setting of the wheels.

4.
Readjust toe-in as outlined in Section 3 (if necessary).

5. With wheels in a straight ahead position and the

steering gear on highpoint, check the steering wheel

alignment by measuring the distance from each hori-

zontal spoke to the horizontal centerline of the

steering wheel (fig. 5). If the horizontal spokes are

over 1-1/8 inches from the horizontal position the

wheel should be removed and centered. (See steering

wheel removal in this section.)

TOE-IN ADJUSTMENT

Adjust the steering linkage for proper toe-in setting as

outlined in Section 3.

CORVETTE STEERING RATIO (Fig. 6)

The Corvette steering ratio may be changed as follows:

CAUTION: Do not use the rearward hole in the

steering arm with power steering equipment or

interference may result.

1.
Remove tie rod ball stud nut at steering arm and

disconnect tie rod from steering arm.

2.
Move tie rod end to forward hole for 17.6:1 ratio

(fast ratio) or rear hole for 20.2:1 ratio (standard

ratio).

3.
Install tie rod stud nut and tighten securely. Repeat

operation on opposite steering arm.
