NOTE:
The valve body assembly must be removed prior to removing the torque converter (with fluid pump)
housing assembly. Failure to ensure this will cause severe damage to both fluid pump seal
assemblies. Also, the load of the valve body pushing on the seals, which in turn push on the pump,
may prevent proper pump installation into the case. Refer to control valve body assembly removal.
