subsequent transmission failure. Refer

to Linkage Adjustments in Part 7-2,

7-3 or 7-4 for detailed manual linkage

adjustment procedures.

CONTROL PRESSURE

CHECK

When the vacuum diaphragm unit is

operating properly and the downshift

linkage is adjusted properly, all the

transmission shifts (automatic and

kickdown) should occur within the

road speed limits specified in Part 7-5.

If the shifts do not occur within

limits or the transmission slips during

shift point, the following procedure is

suggested to determine engine, trans-

mission, linkage, vacuum diaphragm

unit or valve body problems.

1.
Using the automatic transmis-

sion tester (Fig. 4), attach the tachom-

eter to the engine and the vacuum

gauge to the transmission vacuum line

at the vacuum unit (Fig. 5).

2.
Attach the pressure gauge to the

control pressure outlet at the trans-

mission (Figs. '., and 7).

3.
Firmly apply the parking brake

and start the engine.

On a vehicle equipped with a vacu-

um brake release, apply the service

brakes. The parking brake can not be

used because the brake automatically

releases when the transmission selec-

tor lever is moved to a drive position.

4.
Adjust the engine idle speed lo

the specified rpm. If the engine idle

speed cannot be brought within limits

by adjustment at the carburetor idle

adjustment screw, check the throttle

and downshift linkage for a binding

condition. If the linkage is satisfacto-

ry, check for vacuum leaks in the

transmission diaphragm unit (Fig. 8

or 9) and its connecting tubes and

hoses.
Check all other vacuum oper-

ated units (such as the power brake)

for vacuum leaks.

The transmission consists essentially

of a torque converter, planetary gear

train, two multiple disc clutches, a
one-way clutch and a hydraulic con-

trol system (Fig. 3).

The only adjustments on the trans-
mission proper are the intermediate

and low-reverse bands.
