STEP
#4:
The transmission valve body is a very intricate piece of your transmission and
therefore care should be taken to keeping it clean while working on it. Lay old valve
body on a bench or table so that the swinging park arm is laying towards you.
Remove small e-clip that holds the park arm in place (Fig.#4). Install this arm on the
new valve body. The arm should fit the same as it did on the old valve body.
STEP
#5:
Remove the three screws that hold the old filter on the old valve body. Take the
three screws and either the old filter or a new filter (recommend Turbo Action
#17013 Filter) and place onto the new valve body and tighten down with the three
screws.
NOTE:
Be sure the filter you install has only one pick-up hole. If you are
using a deep pan, be sure the pick-up has only one hole.
STEP #6:

STEP
#7:
Before reinstalling valve body into transmission, take note of the plastic half ball or
square shaped neutral switch on the driver’s side of the transmission inside of the
transmission case, Fig. #5. When installing the valve body, make sure this plastic
half ball does not get damaged, Fig. #6. Either remove the neutral switch or merely
slide the valve body carefully over the plastic. The plastic will retract if you put
pressure on it. Also, do not reinstall accumulator spring(s) which were between valve
body and the case, Fig #3.
STEP #8:
Place valve body back into transmission pushing rod into hole that was mentioned in
STEP #3 (Fig. #2). The rod should be angled toward the outside in the rear of
transmission and towards the center of the transmission in the front. Push rod firmly
towards rear while turning drive shaft.
BUT DO NOT FORCE ROD OR VALVE BODY.

With valve body in place, install ten valve body bolts and tighten to 8-10 ft./lbs.
Caution: Be sure valve body sits flat before tightening.

STEP #11:
Reinstall shift linkage (large piece) and tighten bolt. Adjust linkage to be sure that
shifter is selecting all gears properly.
STEP #12:
Remove kickdown (throttle) linkage from carburetor to the small shaft on the
transmission. It is no longer required.

FRONT BAND (Kickdown) ADJUSTMENT (Except double wrap ): Adjust front
band per the following specs - (a) Locate the adjustment on driver ’s side on the out-
side of the transmission, just ahead of the linkage. (b) You will need a 3/4” wrench
and an open end 5/16” wrench. Break the locknut loose (3/4” nut). Now holding the
lock-nut, turn the square lug in the center of the locknut with your 5/16” open end
wrench. Turn wrench clockwise until wrench becomes snug (10 in./lbs.). Make sure
locknut doesn’t move while tightening the square lug. (c) Now carefully turn 5/16”

3/4” wrench to 35 ft./lbs. (very tight). DO NOT allow the square lug to move while
