turn in each manual lever detent posi-

tion. If the manual valve binds against

the actuating pin in any detent posi-

tion, loosen the valve body attaching

bolts and move the body away from

the center of the case. Move the body

only enough to relieve the binding.

bore of the vacuum diaphragm unit

and install the diaphragm unit. Make

sure the control rod enters the throttle

valve as the vacuum unit is installed.

2.
Torque the diaphragm unit to

specification.

FLUID FILTER

AND OIL PAN

1.
Position the fluid filter on the
rear clip so that the tang enters the

hole in the filter flange. Then, rotate

the filter (clockwise) until the grom-

met is over the pump inlet port of the

valve body regulator and press the fil-

ter down firmly. Install the filter re-

taining clip.

2.
Place a new gasket on the trans-

mission case and install the pan. In-

stall the attaching bolts and lock

washers and torque the bolts to speci-

fication.

If the converter and converter hous-

ing were removed from the transmis-

sion, install these components. Posi-

tion the transmission assembly on the

transmission jack, and refer to Trans-
