Check the output shaft endplay using a dial indicator,
as shown in Figure 17-44. If the endplay is not within spec-
ifications, the original selective fit thrust washer must be
replaced. Most units have only one selective-fit thrust
washer. Do not try to adjust endplay by changing other
washers.
If not done already, install the servos in the trans-
mission case. Then, install the band apply linkage and
adjust the bands to specifications. In many cases, the
proper band adjustment is obtained by changing the length
of the band apply pin. Proper pin length is usually obtained
using a special tool and a torque wrench, as illustrated in
Figure 17-45. The special tool is installed along with the
existing band apply pin. Then the pin is applied against the
band using the torque wrench. The correct torque must be
applied for the reading to be accurate. If the pin is the
correct length, a white line will appear in the tool’s
window. If the pin is incorrect, a new pin must be obtained.
Other bands are adjusted using a special tool and a
dial indicator. The tool is installed with the servo piston.
Then, the dial indicator is installed and set to zero. Finally,
the piston is pushed downward to tighten the band against
the drum and the dial indicator is read. See Figure 17-46.

Caution: Never install a transmission on a
vehicle if the input and output shafts are
binding. The transmission will be badly
damaged if it is operated with binding shafts.
Note: Some makers specify input and out-
put shaft endplay specifications. Check
both input and output shaft endplay when
specified. Never attempt to compensate for exces-
sive endplay at one shaft by reducing endplay at the
other shaft.
