lock DODGE RAM SRT-10 2006 Service Repair Manual

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 enterspawl. Move rod to check engagement.
CAUTION: It is possible for the park rod to displace into a cavity just abovethe 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 overpistonandouterspringtoholditin
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 bodyinplace.
11. Tighten valve body bolts alternately and evenly to 11 Nꞏm (100 in. lbs.)torque.
12. Install new fluid filter on valve body. Tighten filter screws to 4 Nꞏm (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 Nꞏm (125 in. lbs.) torque.
18. Lower vehicle and fill transmission with Mopar
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 adjustingscrew 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.
