Use liberal quantity of petroleum jelly to hold thrust
plate in position on piston.
(5) Install overdrive piston thrust bearing in direct
clutch hub (Fig. 171). Use liberal quantity of petro­
leum jelly to hold thrust bearing in place. Note that
one side of bearing has dark coated surface.
This surface faces overdrive piston. Also be
sure raised shoulder on inside diameter of
bearing faces forward as well.
(6) Apply small amount of petroleum jelly to pilot
hub of intermediate shaft.
(7) Verify alignment of splines in overdrive unit
planetary gear and overrunning clutch. Be sure
Alignment Tool 6227-2 is fully seated (Fig. 172). If

become misaligned, overdrive unit cannot be
fully installed on intermediate shaft. Overdrive
unit will have to be disassembled in order to re­
align splines.
(8) Carefully withdraw alignment tool from over­
drive unit.
(9) Lubricate intermediate shaft splines and bush­
ing surfaces with transmission fluid or petroleum
jelly.
(10) Install overdrive unit. Be sure governor tubes
are aligned with feed holes in piston retainer boss.
Intermediate shaft is snug fit in overdrive planetary
gear and overrunning clutch. If overdrive unit will
not seat fully, rotate overdrive output shaft slightly
to align splines and try again.

OVERDRIVE UNIT AND PISTON
INSTALLATION
(1) Install new seals on overdrive piston. Then lu­
bricate seals with Mopar Door Ease, or Ru-Glyde to
ease installation.
(2) Install overdrive piston in retainer. Align lo­
cating lugs on piston in locating bores in re­
tainer (Fig. 169). Use thin plastic strip or feeler
gauge to help guide piston outer seal into retainer.
