4. Make band apply pin selection check to determine
possible cause of malfunction (fig. 13T).
Rear Band Apply Pin Selection
a. Attach band apply pin selection Gauge J-21370-
5 and J-21370-6 to transmission case with
attaching screws checking to make certain the
gauge pin does not bind in servo pin hole (fig.
13T).
b. Apply 25 ft. lb. torque and select proper pin to
be used during assembly of transmission.
Selecting proper length pin is equivalent to adjusting
band. The band lug end of each selective apply pin bears
indentification in the form of one, two or three rings.
c. If both steps of J-21370-5 are below the gauge
surface, the long pin, identified by 3 rings,
should be used.
d. If the gauge surface is between the steps, the
medium pin, identified by 2 rings, should be
used.
e. If both steps are above the gauge surface, the
short pin, identified by 1 ring, should be used.
NOTE: If the transmission is in the vehicle,
be careful when the detent solenoid is
removed as it prevents the spacer plate and
gasket and check balls from dropping down.
