and cam with ATF Plus transmission fluid.
REAR BAND, LOW-REVERSE DRUM AND REAR
SUPPORT INSTALLATION
A different rear band and linkage is used in 30RH
and 32RH transmissions.
The 30RH transmission has a single wrap rear
band, one pivot pin and a band link to connect the
lever (Fig. 129). The lever adjusting screw is in direct
contact with the servo piston. A strut is used to con-
nect the lever to the band lug.
