8. Remove the screws that attach the valve body lower housing to the upper housing and transfer plate. (Figure 10). Note the position of the boost valve tube brace for assembly reference.
9. Remove the lower housing and overdrive separator plate from the transfer plate (Figure 10).
10. Remove the transfer plate from the upper housing (Figure 11).
CAUTION: Do NOT turn the upper housing over or check balls will fall out.
11. Turn the transfer plate over so that the upper housing separator plate is facing upward.
12. Remove the brace plate from the upper housing separator plate and transfer plate (Figure 12).
13. Remove the upper housing separator plate from the transfer plate (Figure 13). Note the position of the filter in the separator plate for assembly reference.
14. Cover the rear clutch check ball with your thumb and then turn the transfer plate over just enough to remove the reverse servo check ball from the transfer plate (Figure 14). Discard the removed check ball.
C. Valve Body Assembly:
1. Remove the filter screen from the upper housing separator plate and install it on the supplied upper housing separator plate (Figure 15). Discard the old separator plate.
2. Align and position the provided upper housing separator plate on the transfer plate (Figure 16).
3. Install the brace plate (Figure 16). Tighten the brace plate attaching screws to 35 in-lbs (4 N-m).
4. Install the remaining separator plate attaching screws. Tighten the attaching screws to 35 in-lbs (4 NM).
5. Position the upper housing so that the internal passages and check ball seats are facing upward. Make sure that the seven (7) check balls are properly positioned (Figure 17).
6. Position the assembled transfer plate and upper housing separator plate on the upper housing (Figure 18). Be sure that the filter screen is seated in the proper housing recess.
7. Position the lower housing separator plate on the transfer plate (Figure 19).
8. Install the lower housing on the assembled transfer plate and upper housing (Figure 20).
9. Install the tube brace and start all valve body screws by hand. Then tighten the screws evenly to 35 in-lbs (4 NM). Start at the center and work out to the sides when tightening the screws.
10. Position the valve body assembly so that the lower housing is facing upward (Figure 21).
