Line Pressure Adjustment; Throttle Pressure Adjustment; Front And Rear Servos - Jeep J-10 Series 1982 Technical & Service Manual

Because line and throttle pressure are interdependent
(each affects shift quality and timing), both adjust
ments must be performed properly and in the correct
sequence which is; line pressure adjustment
first—throttle pressure adjustment last.
Line Pressure Adjustment
(1) Measure distance from valve body to inner edge
of adjusting screw using accurate steel scale (fig. 2C-22).

(2) Distance measured should be 1-5/16 inches (33.4
mm).
(3) If adjustment is required, turn adjusting screw
in or out to obtain 1-5/16 inch (33.4 mm) setting.
NOTE: The 1-5/16 inch (33.J, mm) setting is an approx
imate setting. Because of manufacturing tolerances, it
may be necessary to vary from this dimension to obtain
the desired pressure. One complete turn of the adjusting
screw changes line pressure approximately 1-2/3 psi (9
kPa). Turning the adjusting screw counterclockwise in
creases pressure while turning the screw clockwise de
creases pressure.
Throttle Pressure Adjustment
(1) Insert Gauge Tool J-24031 between throttle lever
cam and kickdown valve (fig. 2C-23).
(2) Push gauge tool inward to compress kickdown
valve against spring and to bottom throttle valve in
valve body.
(3) Maintain pressure against kickdown valve
spring and turn throttle lever stop screw until screw
head touches throttle lever tang and throttle lever cam
touches gauge tool.
NOTE: The kickdown valve spring must be fully com
pressed and the kickdown valve completely bottomed in
the valve body to obtain a correct adjustment.

(1) Clean all mating surfaces. Be sure burrs are
removed from transmission case and valve body steel
plate surfaces.
(2) Position accumulator spring on valve body.
(3) Insert park lock rod through opening in rear of
case.
(4) Position knob on end of lock rod against reaction
plug in sprag and exert rearward pressure on rod to
move rod past sprag. Rotate output shaft, if necessary.
(5) Align and install valve body. Install attaching
screws finger-tight only.
(6) Install neutral switch.
(7) Move manual valve (in valve body) to neutral
position. Align valve body as necessary to align neutral
finger of manual lever with neutral switch plunger.
(8) Tighten valve body attaching screws alternately
and evenly to 100 inch-pounds (11 N»m) torque.
(9) Install oil filter. Tighten attaching screws to 35
inch-pounds (4 N»m) torque.
(10) Install manual and throttle valve control levers
and tighten clamp bolts. Check both shafts for binding
after tightening bolts.
(11) Install oil pan and replacement gasket. Tighten
oil pan bolts to 150 inch-pounds (17 N»m) torque.
(12) Lower vehicle.
(13) Fill transmission with Jeep, Dexron, or equiva
lent automatic transmission fluid. Refer to Fluid Level
and Condition for refill procedure.
(14) Adjust gearshift and throttle linkage.
Front and Rear Servos
The front and rear servos may be removed, recondi
tioned and installed with the transmission in the
vehicle.
For removal, inspection and installation procedures,
refer to Out-Of-Vehicle Service and Overhaul section.
