justment must be performed properly and in the cor-
rect sequence. The correct sequence is line pressure
adjustment first and throttle pressure adjustment
last.
Line Pressure Adjustment
Measure distance from the valve body to the inner
edge of the adjusting screw with an accurate steel
scale (Fig. 124).
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.
The 33.4 mm (1-5/16 in.) setting is an approxi-
mate setting. Because of manufacturing toler-
ances, it may be necessary to vary from this
dimension to obtain desired pressure.
One complete turn of the adjusting screw changes
line pressure approximately 1-2/3 psi (9 kPa). Turn-
ing the adjusting screw counterclockwise increases
pressure while turning the screw clockwise decreases
pressure.
Throttle Pressure Adjustment
Insert Gauge Tool C-3763 between the throttle le-
ver cam and the kickdown valve stem (Fig. 125).
Push the gauge tool inward to compress the kick-
down valve against the spring and bottom the throt-
tle valve.
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.
The kickdown valve spring must be fully com-
pressed and the kickdown valve completely
bottomed to obtain correct adjustment.
TRANSMISSION ASSEMBLY TIPS
Do not allow dirt, grease, or foreign material to en-
ter the case or transmission components during as-
sembly. Keep the transmission case and componentsclean. Also make sure the tools and workbench area
used for assembly are equally clean.
Shop towels used for wiping off your hands and
service tools must be made oflint freematerials.
Lint will adhere to transmission parts and could in-
terfere with valve operation, or even restrict fluid
passages.
Lubricate the transmission components with Mopar
ATF Plus during reassembly. Use Mopar Door-Ease,
or Ru-Glyde on seals and O-rings to ease installation.
Petroleum jelly can also be used to hold thrust
washers and plates in position during assembly oper-
ations. However,do notuse chassis grease, bearing
grease, white grease, or similar lubricants on any
transmission part. These types of lubricants can
eventually block or restrict fluid passages and valve
operation. Use petroleum jelly only.
Do not force parts into place. Most of the transmis-
sion components are easily installed by hand when
properly aligned. If a part seems extremely difficult
to install, it is either misaligned or incorrectly assem-
bled. Also verify that thrust washers, thrust plates
and seal rings are correctly positioned before assem-
bly. These parts can interfere with proper assembly if
mispositioned or ``left out'' by accident.

(c) Slide low-reverse drum through band (Fig.
132). Then tilt drum slightly and start clutch race
into overrunning clutch rollers.
(d) Rotate drum in clockwise direction and push
drum inward until race is seated in overrunning
clutch.
(e) Install rear band lever (Fig. 133). Be sure le-
ver pivot pin is fully seated in case afterward.
(2) On 30RH transmission, install band compo-
nents and low-reverse drum as follows:
