(8) Examine bolt holes in overrunning clutch cam.
Note that one hole is not threaded (Fig. 146). This
hole must align with blank area in clutch cam bolt
circle.
NOTE: The bolt holes in cam are slightly counter-
sunk on one side. This side of cam faces rearward
(toward rear support).
(9) Lubricate overrunning clutch rollers, springs
and cam with Mopar ATF Plus 3, type 7176, trans-
mission fluid.
(10) Position overrunning clutch on a clean, flat
work surface with countersunk holes downward.
(11) Place rear of low-reverse drum over overrun-
ning clutch and align clutch rollers to hub of drum.
(12) While slightly pivoting low-reverse drum,
push hub of drum into overrunning clutch. Verify
that countersunk holes are facing outward. Cam
should be able to rotate in the drum clockwise
only.
(13) Insert a suitable awl through the rear support
mounting hole closest to the pan sealing face. The
awl should be next to the wide space area at the
back of transmission case.
(14) Insert low-reverse drum and overrunning
clutch into front of transmission case and into rear
band.

the non-threaded hole in the overrunning clutch cam.
Verify that non-threaded hole is aligned with wide
space area on transmission case.

between cam and case.
(17) Install overrunning clutch cam bolts. Clutch
cam bolts are shorter than rear support bolts.
