Dodge Ram Truck 1500-2500-3500. Manual — part 1815

3. Install throttle lever (1) in upper housing. Then

install manual lever (2) over throttle lever and start
manual lever into housing.

4. Align manual lever with detent ball and manual

valve (3). Hold throttle lever upward. Then press
down on manual lever until fully seated. Remove
detent ball retainer tool after lever is seated.

5. Then install manual lever seal, washer and E-clip.

6. Verify that throttle lever is aligned with end of kick-

down valve (4) stem and that manual lever arm is
engaged in manual valve.

7. Lubricate solenoid case connector (1) O-rings and

shaft of manual lever with light coat of petroleum
jelly.

8. Attach solenoid case connector to 3-4 accumulator

with shoulder-type screw. Connector has small
locating tang that fits in dimple at top of accumula-
tor housing (2). Seat tang in dimple before tighten-
ing connector screw.

9. Install solenoid assembly and gasket. Tighten sole-

noid attaching screws to 8 N·m (72 in. lbs.) torque.

10. Verify that solenoid wire harness is properly

routed. Solenoid harness must be clear of manual
lever and park rod and not be pinched between
accumulator housing and cover.

11. Position line pressure adjusting screw in adjusting

screw bracket.

12. Install switch valve spring on tang at end of

adjusting screw bracket.

13. Position adjusting screw bracket on valve body.

Align valve springs and press bracket into place.
Install short, upper bracket screws first and long
bottom screw last. Verify that valve springs and
bracket are properly aligned. Then tighten all
three bracket screws to 4 N·m (35 in. lbs.) torque.

14. Perform Line Pressure and Throttle Pressure

adjustments. (Refer to 21 - TRANSMISSION/
TRANSAXLE/AUTOMATIC/VALVE BODY - ADJUSTMENTS)

GOVERNOR BODY, SENSOR AND SOLENOID

1. Turn valve body assembly over so accumulator side of transfer plate is facing down.

2. Install new O-rings on governor pressure solenoid and sensor.

3. Lubricate solenoid and sensor O-rings with clean transmission fluid.

4. Install governor pressure sensor in governor body.

5. Install governor pressure solenoid in governor body. Push solenoid in until it snaps into place in body.

6. Position governor body gasket on transfer plate.

7. Install retainer plate on governor body and around solenoid. Be sure solenoid connector is positioned in retainer

cutout.

8. Align screw holes in governor body and transfer plate. Then install and tighten governor body screws to 4 N·m

(35 in. lbs.) torque.

9. Connect harness wires to governor pressure solenoid and governor pressure sensor.

10. Install fluid filter and pan.

11. Lower vehicle.

12. Fill transmission with recommended fluid and road test vehicle to verify repair.

INSTALLATION

1. Check condition of O-ring seals (1) on valve body

harness connector (2). Replace seals on connector
body if cut or worn.

2. Check condition of manual lever shaft seal (2) in

transmission case. Replace seal if lip is cut or
worn. Install new seal with 15/16 deep well socket
(1).

3. Check condition of seals on accumulator piston. Install new piston seals, if necessary.

4. Place valve body manual lever in low (1 position) so ball on park lock rod will be easier to install in sprag.

5. Lubricate shaft of manual lever with petroleum jelly. This will ease inserting shaft through seal in case.

6. Lubricate seal rings on valve body harness connector with petroleum jelly.

7. Position valve body in case and work end of park lock rod into and through pawl sprag. Turn propeller shaft to

align sprag and park lock teeth if necessary. The rod will click as it enters pawl. Move rod to check engagement.

CAUTION: It is possible for the park rod to displace into a cavity just above the pawl sprag during instal-
lation. Make sure the rod is actually engaged in the pawl and has not displaced into this cavity.

8. Install accumulator spring and piston into case. Then swing valve body over piston and outer spring to hold it in

place.

9. Align accumulator piston and outer spring, manual lever shaft and electrical connector in case.

10. Then seat valve body in case and install one or two bolts to hold valve body in place.

11. Tighten valve body bolts alternately and evenly to 11 N·m (100 in. lbs.) torque.

12. Install new fluid filter on valve body. Tighten filter screws to 4 N·m (35 in. lbs.) torque.

13. Install throttle and gearshift levers on valve body manual lever shaft.

14. Check and adjust front and rear bands if necessary.

15. Install the transmission range sensor (Refer to 21 - TRANSMISSION/AUTOMATIC/TRANSMISSION RANGE

SENSOR - INSTALLATION).

16. Connect solenoid case connector wires.

17. Install oil pan and new gasket. Tighten pan bolts to 13.6 N·m (125 in. lbs.) torque.

18. Lower vehicle and fill transmission with Mopar

T

ATF +4, Automatic Transmission fluid.

19. Check and adjust gearshift and throttle valve cables, if necessary.

ADJUSTMENTS - VALVE BODY

CONTROL PRESSURE ADJUSTMENTS

There are two control pressure adjustments on the valve body;

Line Pressure

Throttle Pressure

Line and throttle pressures are interdependent because each affects shift quality and timing. As a result, both
adjustments must be performed properly and in the correct sequence. Adjust line pressure first and throttle pressure
last.

LINE PRESSURE ADJUSTMENT

1. Measure distance (2) from the valve body to the

inner edge of the adjusting screw with an accurate
steel scale. Distance should be 33.4 mm (1-5/16
in.). If adjustment is required, turn the adjusting
screw in, or out, to obtain required distance setting.

NOTE: The 33.4 mm (1-5/16 in.) setting is an
approximate

setting.

Manufacturing

tolerances

may make it necessary to vary from this dimen-
sion to obtain desired pressure.

One complete turn of the adjusting screw changes line
pressure approximately 1-2/3 psi (9 kPa).

Turning

the

adjusting

screw

counterclockwise

increases pressure while turning the screw clockwise
decreases pressure.

THROTTLE PRESSURE ADJUSTMENT

1. Insert Gauge Tool C-3763 between the throttle

lever cam and the kickdown valve stem (2).

2. Push the gauge tool inward to compress the kick-

down valve against the spring and bottom the throt-
tle valve.

3. Maintain pressure against kickdown valve spring.

Turn throttle lever stop screw until the screw head
touches throttle lever tang and the throttle lever
cam touches gauge tool.

NOTE: The kickdown valve spring must be fully
compressed and the kickdown valve completely
bottomed to obtain correct adjustment.
