Jeep XJ. Manual — part 406
CAUTION: Do not force valves or plugs into place
during reassembly. If the valve body bores, valves,
and plugs are free of distortion or burrs, the valve
body components should all slide into place easily.
In addition, do not overtighten the transfer plate
and valve body screws during reassembly. Over-
tightening can distort the valve body resulting in
valve sticking, cross leakage and unsatisfactory
operation. Tighten valve body screws to recom-
mended torque only.
(1) Lubricate valve body bores, valves and plugs
with Mopar
t ATF Plus 3, Type 7176, transmission
fluid.
(2) Install regulator valve line pressure plug, pres-
sure plug sleeve, regulator valve throttle pressure
plug, and spring into valve body (Fig. 107). Verify
valve components slide freely.
(3) Install regulator valve end plate on valve body
(Fig. 107).
(4) Install kickdown limit valve and spring in kick-
down limit valve body (Fig. 107). Verify valve compo-
nents slide freely.
(5) Compress spring into kickdown limit valve
body.
(6) Install retainer in grooves at end of kickdown
limit valve body (Fig. 107).
(7) Install throttle pressure plug in kickdown limit
valve body (Fig. 107).
(8) Install 1-2 shift valve and spring into valve
body (Fig. 107).
(9) Install 2-3 shift valve and spring into valve
body (Fig. 107).
(10) Install 1-2 shift control valve and spring into
valve body (Fig. 107).
(11) Verify valve components slide freely.
