Kickdown Servo
Direct air pressure into the front servo "apply"
passage. Operation of the servo is indicated by a tight-
ening of the front band. Spring tension on the servo
piston should release the band.
Low und Reverse Servo
Direct air pressure into the rear servo "apply" pas-
sage. Operation of the servo is indicated by a tighten-

Removal and Insfullation
(1)
Remove the screw and retainer securing the
speedometer cable to the extension housing. Careful-
ly work the pinion and sleeve assembly out of the
housing (Fig. 43).
(2) To replace the pinion and/or oil seal, pry the
clip off the pinion and slide the pinion assembly off
the cable. Install a new seal on the cable housing.
If the clutches and servos operate properly, no un-
shift or erratic shift conditions indicate that the mal-
functions exist in the control valve body assembly.
Govern or
Governor operating failures can generally be diag-
nosed by a road test or hydraulic pressure test. Refer
to Page
66.
(3) If transmission fluid is found in the cable hous-
ing, replace the seal inside the pinion bore (Fig.
44).
Pry the old seal out of the pinion bore. Place a new
seal on the end of the cable with the lip toward the
cable housing, then slide the pinion over the seal and
cable. Secure with the spring clip.
(4)
To install, push the pinion and sleeve assembly
into the extension housing
so
the sleeve flange is
tight against the housing, then install the retainer and
screw. Tighten the screw to
150
inch-pounds torque.
