CAUTION: Use converter holding ToolJ-5384

when lowering transmission or keep rear of

transmission lower than front so as not to lose
converter.

The installation of the transmission is the reverse of

the removal.

TURBO HYDRA-MATIC DIAGNOSIS PROCEDURE

Accurate diagnosis of transmission problems begins

with a thorough understanding of normal transmission

operation. In particular, knowing which units are in-

volved in the various speeds or shifts so that the specific

units or circuits involved in the problem can be isolated

and investigated further. Analytical diagnosis will pro-

tect the technician from come backs and certainly will

improve owner satisfaction.

An important and often overlooked aspect of diagnosis

is finding out specifically what the customer is com-

plaining of. For this purpose a short ride with the cus-

tomer will often prove beneficial. It may be found that

the condition the customer wants corrected is standard

and should not be altered.

The following sequence, based on field experience, pro-

vides the desired information quickly and in most cases

actually corrects the malfunction without requiring the

removal of the transmission. Details of the items listed

in this sequence are covered further in the text.

SEQUENCE FOR TURBO HYDRA-MATIC

DIAGNOSIS PROCEDURE

1.
Check oil level and condition.

2.
Check and correct detent switch.

3.
Check and correct vacuum line and fittings.

4.
Check and correct manual linkage.

OIL LEVEL AND CONDITION CHECK

Always check the oil level before road testing. Oil

must be visible on dip stick prior to operating the ve-

hicle. Erratic shifting, pump noise, or other malfunc-

tions can in some cases be traced to improper oil level.

Oil level should be checked with the selector lever in

the Park (P) position, engine running, and the vehicle on

level pavement.

Fluid level should be to the FULL mark with the trans-

mission at normal operating temperature (170°-190°
F.).

With warm fluid (room temperature), the level should be

at or slightly below the ADD mark.

If oil level was low, refer to Oil Leaks.

The condition of the oil is often an indication of whether

the transmission should be removed from the vehicle, or

to make further tests. When checking oil level, a burned

smell and discoloration indicate burned clutches or bands

and the transmission 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

from rolling. The pointer on the indicator quadrant

should line up properly with the range indicators in all

ranges.
OIL LEAKS

Before attempting to correct an oil leak, the actual

source of the leak must be determined. In many cases,

the source of the leak can be deceiving due to "wind flow"

around the engine and transmission.

The suspected area should be wiped clean of all oil be-

fore inspecting for the source of the leak. Red dye is

used in the transmission oil at the assembly plant and

will indicate if the oil leak is from the transmission.

. The use of a "black light"* to identify the oil at the

source of leak is also helpful. Comparing the oil from

the leak to that on the engine or transmission dip stick

(when viewed by black light) will determine the source

of the leak.

Oil leaks around the engine and transmission are gen-

erally carried toward the rear of the car by the air

stream. For example, a transmission "oil filler tube to

case leak" will sometimes appear as a leak at the rear of

the transmission. In determining the source of an oil

leak it is most helpful to keep the engine running.

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.

4-Checking Wheel PuI!-Corvette

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.
