this must be done before the valve body may be
removed. Unbolt the control valve assembly and
carefully lift it to free the governor pipes from the
transmission case (fig. 7-26). Do not bend the governor
pipes. Remove the rear servo assembly by taking out the
six screws that attach it to the transmission body (fig.
7-27). Next, remove the pressure switch/detent solenoid
by unclipping the wires and unbolting the device (fig.
7-28). (This varies to application.) Next, lift the control
valve spacer away from the transmission body (fig.
7-29). Notice the position of the six check balls located
in the transmission case (fig. 7-30); remove these with
a magnet and retain them in a safe place for reinstallation
during reassembly. Remove the front servo piston and
servo piston spring from the case (fig. 7-31). If this item
appears to be in satisfactory condition, do not
disassemble it. After removing the bolts that retain the
oil pump, use two slide hammers to remove the oil pump
from the transmission housing (fig. 7-32). Set the pump
aside for later attention. Next, grasp the turbine shaft and
remove the forward clutch assembly from the
transmission case (fig. 7-33). Figure 7-34 shows the
direct clutch being removed from the transmission
housing followed by the removal of the front band (fig.
7-35). Unclip the snap ring retaining the intermediate
