(10) Install the throttle lever and shaft on the valve
body (Fig. 77). Insert the detent spring and ball in its
bore in the valve body. Depress the ball and spring
with Tool C-3765 or similar tool and slide the manual
lever over the throttle shaft so that it engages the
manual valve and detent ball. Install the retaining
E-clip on the throttle shaft.
(11) Position the valve body assembly on the hold-
ing stand.

chambers with the large ball in the large chamber
(Fig. 73). Place the front pump check valve and spring
in the valve body.
(13) Position the transfer plate assembly on the
valve body. Install the 14 retaining screws, starting
at the center and working outward, tighten the screws
to 28 inch-pounds torque.
(14) Install the torque converter valve and the r e g
ulator valve (Fig. 75).
(15) Position the torque converter valve spring and
regulator valve spring over the ends of their respec-
tive valves. Place the line pressure adjusting screw
assembly on the end of the regulator valve spring
with long dimension of nut at right angles to the
valve body (Fig. 71).
(16) Install the spring retainer, making sure the
converter valve spring is engaged on the tang and
position squarely in the retainer. Tighten the three
retaining screws to 28 inch-pounds torque (Fig. 71).
NOTE:
Measure and if necessary, align the spring
retainer as described on Page
67.
(17) Install the oil filter and tighten the three re-
taining screws to 28 inch-pounds torque.
After the
valve body has been serviced and completely assem-

lined on Page
67.
However, if pressures were satis-
factory prior to disassembly, use the original settings.
ACCUMULATOR PISTON AND SPRING
Inspection
Inspect the two seal rings for wear and make sure
they turn freely in the piston grooves. It is not neces-
sary to remove the rings unless conditions warrant.
Inspect the piston for nicks, burrs, scores and wear.
Inspect the piston bore in the case for scores or other
damage. Inspect the piston spring for distortion. Re-
place parts as required.

(2) Remove the bearing snap ring from the exten-
sion housing.
(3) Drive the bearing rearward out of the exten-
sion housing with Tool (2-3275 (Fig. 49).
(4) Place a new bearing in opening of the exten-
sion housing. Using Tool C-3204, drive the bearing
into the housing (Fig. 50). Install the bearing retain-
ing snap ring.

housing with a long blunt drift. Be sure not to mar
the oil seal surface in the housing.
(2) Press or drive out bushing with Tool C-3974
(Fig. 78).
(3) Slide a new bushing on the installing end
of
Tool (2-3974. Align the oil hole in bushing with the
